FEATURES
1. Broad lineup
Lineup includes reduced-wiring connec-
tor type, die casting type with commonly-
used screw terminals, and a plastic case
type that puts a priority on economy.
2. Superior environmental resistance
The die-cast type has high sealing char-
acteristics that satisfy the IEC IP67.
3. Standardized connector type
We standardized the reduced-wiring and
easy-installation connector type. This
increases worker efficiency when wiring,
maintaining, and replacing.
4. Lineup includes bifucated (twin
contact) type as well as standard load
type.
The lineup includes a standard load type
(5 A, 250 VAC) and a bifucated type (0.1
A, 30 VDC). The bifucated type uses
gold-clad twin contacts, which makes it
ideal for electronic circuit control.
5. Economical plastic case type
A plastic case IP64 economy type is
included as well as the die-cast type. It is
perfect for applications in which econo-
my is the priority.
6. UL/CSA certified.
7. TÜV accredited products also avail-
able.

WIRING (For screw terminal)
1) M3 small binding screw is used as a
terminal screw.
2) When wiring, don’t connect the lead
wire to the terminal directly. Fasten the
crimped terminals securely applying a
tightening torque of 0.20 to 0.29 N·m {2
to 3 kg·cm}. Avoid using solder when
wiring.
3) Refer to the following diagram for
power supply wiring.
4) Take note the terminal arrangement is
different between plunger type and lever
type. (The arrangement of N.C. and N.O.
is reversed.)
5) Mount the terminal case securely after
ensuring that the rubber seals are
attached at the proper positions. Do a
visual check to make sure that the retain-
er is properly inserted on the protrusion
of the case. When installing the terminal
case of the plastic case type, push the
terminal case until it clicks into place,
and make sure there is no play after-
wards.
CONNECTOR TYPE
1) The cord outlet direction is inter-
changeable. Refer to “HOW TO
CHANGE THE CORD OUTLET DIREC-
TION FOR CONNECTOR TYPE”.
2) Do not remove the connector over 50
times.
3) Wiring diagram as shown below.
4) When the angle type of connector
cord is used, the cord outlet direction is
as follows.
Cord outlet direction (Right side)
Cord outlet direction (Left side)

HOW TO CHANGE THE CORD OUTLET DIRECTION FOR CONNECTOR TYPE
The cord outlet direction is interchange-
able both right and left sides. The direc-
tion of connector cord is set to the right
when it is shipped. When it is used left
side direction, follow the next procedure.
Cord outlet direction (Right side)
Cord outlet direction (Left side)
Push down the fitting metal while pulling
it horizontal direction.
Confirm the fitting metal is on tightly.
If it is loosen, it might be cause of the
trouble.
Press up the terminal cover.
Do not put the lead wire between termi-
nal cover and body.
Put the seal rubber at the right place.
Turn the terminal cover at an angle of
180 degree. Follow the step 3.
Do not pull the terminal cover.
Do not rotate the terminal cover many
times.
Do not loosen the terminal screw.
Be careful, because not doing so could
cause wire cutoff and contact failure.
INDICATOR LIGHTING CIRCUIT
(Connector type only)
1) See the circuit diagram.
2) The LED only takes 24 DC V, but
please use a connector designed for AC.
3) Since the LED lamp is connected to
the N.O. side (contact No. 4), please
connect the load to contact No. 4. The
load side should be on the “+” power
supply side. Be careful, because the
LED will break if the connection is
reversed.
4) The LED is turned on when the switch
is at a free position. The LED is turned
off when the switch operates.
5) Applicable power source is 24 V DC.
Use it with care on leakage current. The
leakage current is approx. 1.5 mA at 24
V DC.

CAUTIONS
Die casting case
1) Do not expose HL limit switch to hot
water (over 60°C 140°F) and in a water
vapor environment.
2) Avoid the place where organic sol-
vents, strong acid, strong alkali liquid
and vapor may attach to the products
directly. Prevent using the HL limit switch
in place where inflammable or corrosive
gas will be generated.
3) Do not change the operating position
by bending the actuator.
4) Use within an ambient temperature of
–10 to 80°C. (However, do not allow it to
freeze.)
Plastic case
1) Do not use in water or oil. Do not
place the switch where it is always
exposed to water or dust splash.
2) Do not expose HL limit switch to hot
water (over 60°C 140°F) and in a water
vapor environment.
3) Avoid the place where organic sol-
vents, strong acid, strong alkali liquid
and vapor may attach to the products
directly. Prevent using the HL limit switch
is place where inflammable or corrosive
gas will be generated.
4) Do not change the operating position
by bending the actuator.
5) Use within an ambient temperature of
–10 to 80°C. (However, do not allow it to
freeze.)
5) If OT is too big, the life of limit switch
will be shortened by switching friction.
Use it with enough margin of OT. 70% of
OT standard value will be good.
6) Attach the terminal cover securely to
the body with the metal stop latch to the
projection of the body.
7) Confirmation test in the actual applica-
tion is highly recommended.
8) Do not use the switch in a silicon
atmosphere. Care should be taken
where organic silicon rubber, adhesive,
seling material, oil, grease or lead wire
generates silicon.
9) When used outdoors (in places where
there is exposure to direct sunlight or
rain such as in multistory car parks) or in
environments where ozone is generated,
the influence of these environments may
cause deterioration of the rubber materi-
al. Please consult us if you intend to use
a switch in environments such as these.
10) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
6) If OT is too big, the life of limit switch
will be shortened switching friction. Use it
with enough margin of OT. 70% of OT
standard value will be good for use.
7) Attach the terminal cover securely to
the body to the extent you can identify
the clicking or locking sound.
8) A confirmation test in the actual appli-
cation is highly recommended.
9) Do not use the switch in a silicon
atmosphere. Case should be taken
where organic silicon rubber, adhesive,
sealing material, oil, grease or lead wire
generates silicon.
10) When used outdoors (in places
where there is exposure to direct sunlight
or rain such as in multistory car parks) or
in environments where ozone is generat-
ed, the influence of these environments
may cause deterioration of the rubber
material. Please consult us if you intend
to use a switch in environments such as
these.
11) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
HL (AZH)
Common for all types
1. There are limits to what type of environment can be tolerated.
This limit switch is designed under the premise that it will be used in a standard industrial device. Accordingly, there are limits as to
what can be tolerated if used outdoors or where water and oil, etc., may get on the device. The following table indicates how much
water and oil can be withstood (classification of protective structure).
2. The internal mechanism will break if the actuator is moved beyond its Total-travel (T.T.). Always use within the T.T.

Type Classification
Push plunger type Small Medium Large Excellent Excellent High-level accuracy gives firm detection for position
fixing, etc., by using perpendicular movement.
Roller plunger type
(includes cross
roller plunger) Small Medium Large Excellent Excellent Operating range can be widened by mounting
accessory actuators like cams, dogs, cylinders, etc.
High-level detection for position fixing.
Roller arm type Small to
large Large Medium Good to
excellent Excellent
The stroke in the direction of revolution is large at
between 45° and 90° and the lever angle can be set
at will to within 360° for easy use. Wide angle type
(large O.T.) available. Can be used for wide-range
position fixing.
Adjustable roller
arm type Small to
large Large Medium Good to
excellent Good Lever length can be altered to allow rough operation
detection using the roller lever characteristics.
Adjustable rod type Large Large Medium Good Good
Wide range of operations, and convenient for
uneven mountings. Lightest operation among the
revolving operation type of limit switches. Rod length
is adjustable, and bending is also easy.
Fork Large Medium Medium Good Excellent
If operated up to 55° position, revolves automatically
to retain 90° position. Two dog operation enables
recovery operation through single dog, or for any-
thing that has caused the roller position to slip.
Spring wire and
flexible rod Medium Large Small Possible Possible
Excluding the thread direction, direction can be
adjusted up to 360°. Operating power is the lowest
of the limit switches, and is effective in detecting
when direction and conditions are uneven. In order
to absorb the movements after operation in the actu-
ator part, work slippage tolerances are also large.
Hinge lever type Large Medium Small Possible Possible Using a low speed, low torque cam, the lever can
assume various shapes suited to the operation. The
lever is very sturdy.
Roller lever type Large Medium Small Possible Possible Suited to high speed cams through the attachment
of a hinge roller lever.
One way roller lever
type Medium Medium Medium Possible Possible
Operation is possible with both hinge lever type and
one way operation, but the roller will break if operat-
ed in the opposite direction, rendering the unit inop-
erable. Can be used to prevent opposite direction
movement.
Roller lever type Medium Medium Medium Possible Possible The roller position can be changed.

CAUTIONS FOR USE
Pay attention to the following points
when designing the dog for limit switch
operation.
1. Make the dog faceplate as smooth
as possible.
2. Adjust both the dog angle and the
set arm angle as below, depending on
the operating speed.
3. The depth (h) of the dog effects the
lifespan of the limit switch. Therefore,
set the depth to a maximum of 80% of
the Total Travel (T.T.)
4. The relationship between the speed
of the dog (V = m/s) and the tip angle
(α) is as follows:
1) V&0.2m/s
3) 0.5m/s !V&2m/s
Because the arm jiggle is as a mini-
mum at a comparative speed such as
V&0.5m/s, setting both the dog angle
so that it travels perpendicularly and
the arm angle to 45° is optimum.
If overriding the dog, set the arm per-
pendicularly, so that α=45°. If the dog
angle is reduced, the tolerable speed
is increased.
5) Roller plunger type
DESIGN OF OPERATING DOG AND OPERATING SPEED
When V&0.2m/s, set the arm to per-
pendicular and set the arm rise angle
to between 45° and 90°. If the dog rise
angle is reduced, the maximum tolera-
ble speed is increased.
As a rule, α= 45° is optimum.
2) V&0.5m/s
The maximum tolerable speed can be
extended by further reducing the dog
rise angle from 45° when 0.5m/s !
V&2m/s. It is necessary to set the arm
so that the dog’s cutting surfaces are
always parallel (
θ
o = 90°– α)

Even if overriding the dog, set the for-
wards and rearwards motion exactly
the same, and avoid any settings that
make the actuator accelerate rapidly
from the dog.
5. Operation speed
1) When the operation (acting and
reverting) speed is exceedingly slow,
switching of the contacts will become
unstable and this could cause prob-
lems such as failure to make contact
and welding. As a guide, the speed
should be at least 1mm/s.
2) When the operation (acting and
reverting) speed is exceedingly fast,
be careful because the violent motion
could cause breakage and with
increased frequency, contact switching
will not be able to keep up. As a guide,
the switching frequency should be
within 20 times per minute.

1. The ON/OFF circuit for the guidance
load may suffer contact damage due to
surges or inrushes when the power is
turned either ON or OFF.
Consequently, insertion of a protective
circuit as per the following diagram is
recommended, in order to protect the
contacts.
2. Do not connect either irregular poles
or power sources to a switch contact.
Power connection examples (irregular
pole connection)
3. Avoid circuits where power may find
a way between the contact points (as
this may cause welding.)

4. Using electronic switch circuits (low
power, low current)
1) Bouncing and chattering are gener-
ated due to collision between the con-
tacts when the limit switch is switching
between them, and this sometimes
causes such problems as white noises
and error pulses in both the electronic
circuit and the reverberation equip-
ment.
2) If the generation of bouncing and
chattering becomes a problem, it is
necessary to consider installing a CR
circuit or other absorption circuit given
the circuit design.
3) This is particularly necessary when
high contact reliability is needed, and
is unsuitable for silver contact switch-
es. Switches with gold contacts pos-
sess excellent performance.

CAUTIONS FOR USE
CAUTIONS FOR USE

1) Do not attempt to physically alter
any part of the switch itself, such as
the actuator, or switch attachment
vent, as this may cause alterations to
both characteristics and performance,
and damage the insulation.
2) Do not pour any lubricants such as
oil or grease onto the moving parts of
the actuator, as there is a possibility
that this will cause a malfunction due
to seepage into the inside, and impair
the motion. Silicon-based grease in
particular affects the contact points
badly.
3) If the switches are not to be used for
an extended period of time, their con-
tact reliability may be reduced due to
oxidation of the contact points.
Because accidents may result from the
impaired conductivity, always imple-
ment a check beforehand.
4) Prolonged continuous use of the
switch hastens deterioration of the
parts (especially the seal rubber) and
may cause a malfunction in the
release. For this reason, always imple-
ment a check beforehand.
5) Usage in the vicinity of either the
switch operating position (O.P.) or the
release position (R.P.) results in unsta-
ble contacts. If using the NC contact
point, set the actuator to return to the
free position (F.P.) Also, is using the
NO contact point, hold the ratings val-
ues down to 70 to 100% for the over-
travel (O.T.)
6) If the actuator is forced beyond its
total travel (T.T.), the internal mecha-
nism may be damaged. Always use
within the T.T.
7) Do not apply unreasonable force to
the actuator, as this may result in dam-
age and impaired movement.
8) The switch, if dropped, may break
due to excessive vibration and impact.
Therefore, please use extra caution
when transporting and installing.
9) Condensation inside the switch may
occur if there are rapid ambient tem-
perature changes when the switch is in
a high temperature and humidity.
Since this occurs easily during marine
transport, be extra cautious of what the
environment will be when shipping.
Condensation is the phenomenon in
which water vapor condenses into
switch-adhering water droplets when
the temperature rapidly drops in a
high-temperature, high-humidity
atmosphere or when the switch is
quickly moved from a low temperature
location to a place of high temperature
and high humidity. It is the cause of
insulation deterioration and of rust.
10) Be careful of freezing in tempera-
tures below 0°C. Freezing is the phe-
nomenon in which moisture adhering
to the switch from condensation or
when in unusually high-humidity envi-
ronments freezes onto the switch
when the temperature drops below the
freezing point. Please extra caution
because freezing can lock moving
parts, cause operational delays, or
interfere with conductivity when there
is ice between the contacts.
11) In low-temperature, low-humidity
conditions, plastic becomes brittle and
the rubber and grease harden, which
may lead to malfunction.
12) Long term storage (including dur-
ing transport) in high temperature or
high humidity environments or where
the atmosphere contains organic or
sulfide gas, will cause sulfide or oxide
membrane to form on the contact sur-
faces. This in turn will cause unstable
or failed contacting that may lead to
functional malfunction. Please verify
the atmosphere when storing and
transporting.
13) Packaging should be designed to
reduce as much as possible the poten-
tial influence of humidity, organic gas,
and sulfide gas, etc.
14) Please avoid sudden changes in
temperature. This is a cause of switch
deformation and encourages the seal
structure to breathe, which may lead to
seal failure and operational malfunc-
tion.
15) If installing a thermoplastic resin
case, the use of a spring washer tight-
ened directly against the case will
cause the case to collapse and
become damaged. Therefore, please
add a flat washer before tightening.
Also, be careful not to install if the
case is being twisted.
16) For the purpose of improving quali-
ty, materials and internal structure may
be changed without notice.
17) When used outdoors (in places
where there is exposure to direct sun-
light or rain such as in multistory car
parks) or in ambient temperature envi-
ronments where ozone is generated,
the influence of these environments
may cause deterioration of the rubber
material. Please consult us if you
intend to use a switch in such environ-
ments.

FOREIGN STANDARDS OVERVIEW
1. International Standards
IEC standard
International Electrotechnical Commission
By promoting international cooperation toward all
problems and related issues regarding
standardization in the electrical and electronic
technology fields, the IEC, a non-governmental
organization, was started in October, 1908, for the
purpose of realizing mutual understanding on an
international level. To this end, the IEC standard
was enacted for the purpose of promoting
international standardization.
2. North America
UL (Underwiters Laboratories Inc.)
This is a non-profit testing organization formed in
1894 by a coalition of U.S. fire insurance firms,
which tests and approves industrial products
(finished products). When electrical products are
marketed in the U.S., UL approval is mandated in
many states, by state law and city ordinances. In
order to obtain UL approval, the principal parts
contained in industrial products must also be UL-
approved parts.
UL approval is divided into two general types. One
is called “listing” (Fig. 1), and applies to industrial
products (finished products). Under this type of
approval, products must be approved
unconditionally. The other type is called
“recognition” (Fig. 2), and is a conditional approval
which applies to parts and materials.
CSA (Canadian Standards Association)
This was established in 1919 as a non-profit, non-
governmental organization aimed at promoting
standards. It sets standards for industrial products,
parts, and materials, and has the authority to judge
electrical products to determine whether they
conform to those standards. The CSA is the ultimate
authority in the eyes of both the government and the
people in terms of credibility and respect. Almost all
states and provinces in Canada require CSA
approval by law, in order to sell electrical products.
As a result, electrical products exported from Japan
to Canada are not approved under Canadian laws
unless they have received CSA approval and
display the CSA mark. Approval is called
“certification”, and products and parts which have
been approved are called “certified equipment”, and
display the mark shown in Fig. 3. The mark shown
in Fig. 4 is called the “Component Acceptance”
mark, and indicates conditional approval which is
applicable to parts. The C-UL mark shown in Fig. 5
(finished products) and Fig. 6 (parts) indicates that
the product has been tested and approved in UL
laboratories, based on UL and CSA standards,
through mutual approval activities.
3. Europe
EN standard
European Standards/Norme Europeennee
(France)/Europaishe Norm (Germany)
Abbreviation for European Standards. A unified
standard enacted by CEN/CENELEC (European
Standards Committee/European Electrical
Standards Committee). EU and EFTA member
nations employ the content of the EN standards into
their own national standards and are obligated to
abolish those national standards that do not agree
with the EN standards.
(1) Germany
VDE (Verband Deutscher Elektrotechniker)
The VDE laboratory was established mainly by the
German Electric Technology Alliance, which was
formed in 1893. It carries out safety experiments
and passes approval for electrical devices and
parts. Although VDE certification is not enforced
under German law, punishment is severe should
electrical shock or fire occur; therefore, it is, in fact,
like an enforcement.
TÜV (Technischer Überwachungs-Verein)
TÜV is a civilian, non-profit, independent
organization that has its roots in the German Boiler
Surveillance Association, which was started in 1875
for the purpose of preventing boiler accidents. A
major characteristic of TÜV is that it exists as a
combination of 14 independent organizations (TÜV
Rheinland, TÜV Bayern, etc.) throughout Germany.
TÜV carries out inspection on a wide variety of
industrial devices and equipment, and has been
entrusted to handle electrical products, as well, by
the government. TÜV inspection and certification is
based mainly on the VDE standard.
TÜV certification can be obtained from any of the 14
TÜVs throughout Germany and has the same
effectiveness as obtaining VDE certification.

when ordering.
What are EN standards?
An abbreviation of Norme Europeenne
(in French), and called European
Standards in English. Approval is by vote
among the CEN/CENELEC member
countries, and is a unified standards lim-
ited to EU member countries, but the
contents conform to the international
ISO/IEC standards.
If the relevant EN standard does not
exist, it is necessary to obtain approval
based on the relevant IEC standard or, if
the relevant IEC standard does not exist,
the relevant standard from each country,
such as VDE, BS, SEMKO, and so forth.
CE markings and EC
directives
The world’s largest single market, the
European Community (EC) was born on
1 January 1993 (changing its name to
EU in November 1993. It is now always
expressed as EU, apart from EC direc-
tives.) EU member country products
have always had their quality and safety
guaranteed according to the individual
standards of each member country.
However, the standards of each country
being different prevented the free flow of
goods within the EU. For this reason, in
order to eliminate non-tariff barriers due
to these standards, and to maximize the
merits of EU unification, the EC direc-
tives were issued concomitant to the
birth of the EU.
The EN standards were established as
universal EU standards in order to facili-
tate EU directives. These standards
were merged with the international IEC
standards and henceforth reflect the
standards in all countries. Also, the CE
markings show that products conform to
EC directives, and guarantee the free
flow of products within the EC.
Appropriate EC directives
for control equipment
products
The main EC directives that are to do
with machinery and electrical equipment
are the machinery directive, the EMC
directive, the low voltage directive, and
the telecom directive. Although these
directives have already been issued, the
date of their enactment is different for
each one. The machinery directive was 1
January 1995. The EMC directive was 1
January 1996, and the low voltage direc-
tive was enacted from 1 January 1997.
The telecom directive was established by
the separate CTR (Common Technology
references.)
