A compact and accurate vertical limit switch. Type with a lamp which makes main-
tenance convenient; either a neon AC powered lamp or an LED DC powered lamp.
FEATURES
1. Compact design approximately 1/3
of the AZ5 limit switches
2. Au-clad contacts that can even use
low level circuit and little chattering
and bouncing
The built-in switch has Au-clad contacts
with excellent contact reliability and uses
a crossbar contact method, and more-
over, has a dual cutoff circuit (1 Form A
1 Form B contact) with little chattering
and bouncing due to computer-operated
analysis.
3. Easy wiring with full-open terminals
When the cover is removed, the termi-
nals are open as far as the flank, so the
necessity to insert your fingers into a
case to complete the wiring has been
removed. Moreover, the wiring space is
large despite the compact size, and the
terminals are spread in a tiered array, so
that wiring work can be completed very
easily.
The cable can either be screwed in
directly, or can use U-shaped and circu-
lar pressure terminals.
4. Mounting are possible to both front
and back
5. Type with a lamp that can be used
with a wide range of voltages
• With neon lamp
Compatible with: 100 and 200V AC ;
Even at 100V AC, sufficient luminosity is
achieved through the diamond-cut lens.
Also with a long lifespan of more than 20
thousand hours.
• With LED lamp
Covers 6 to 48V DC and comes in three
types, 6V DC , 12V DC , 24 to 48V DC
Uses two highly luminescent LEDs and
in addition, sufficient luminosity is
achieved through the diamond-cut lens.
6. Lamp connection can be either
spring type or lead wire type
• Spring type (wiring unnecessary)
(With neon or LED lamp type)
Wiring is unnecessary because the lamp
is directly connected to the terminals. By
simply changing the direction of the lamp
holder attachment, it is possible to dis-
play both lights during inoperability and
during operation (however, if both N.O.
and N.C. loads are connected, only the
inoperability lamp can be displayed.)
Construction permits lamp attach-
ment method to be changed.
• Lead wiring type <Current leakage: 0>
(LED lamp type only)
Because the wiring can be made parallel
to the load, current leakage from the
lamp can be reduced to 0. Even with a
slight leak, the electronic circuit incurring
the leak can be used safely.
7. Dust-proof, waterproof, oil resistant
construction
The main unit and the cover are sealed
with rubber packing, and the cord runner
is doubly sealed by the cord vent. The
actuator is sealed by both a rubber cap
and an O ring in all models. Also, the
lens and cover are formed simultaneous-
ly with the lamp type, and moreover, a
nameplate is affixed to the upper sur-
face, thereby improving the already
excellent waterproof capabilities.
(Note: Applications directly involving the
cord entrance and the locations which
are always wet and oily, or submersion
in water or oil, cannot be used.)
TYPICAL APPLICATIONS
Ideal for general plant facilities such as
engineering machinery, conveyer
machinery, and assembly lines
LED lamp type is also compatible with
low-voltage DC control circuits such as in
PCs and computers.

LAMP LIGHTING CIRCUIT
1. Spring type
1) When connecting load to N.O. side:
When the switch is at free position, the
lamp is lit, and when the switch operates,
the lamp turns off. (Use the lamp holder
in the same condition as when it was at
the time of shipment.)
2) When connecting load to N.C. side:
When connecting switch is at free posi-
tion, the lamp turns off, and when the
switch operates, the lamp is lit.
(Use the lamp holder, changing it direc-
tion by 180°.)
3) When connecting loads to both N.O.
and N.C. sides: Same as in 1).
(Use the lamp holder in the same condi-
tion as when it was at the time of ship-
ment. In this case, it is impossible to use
it, changing its direction by 180°.)
(With LED)
1) When giving indication on N.O. side
and N.C. side, operation is same as that
in the case of the spring type. However,
when load is connected to both N.O. side
and N.C. side, indication can be given on
both N.C. side and N.O. side.
2) When the indication circuit is connect-
ed with load in parallel:
Load performs the same operation as
the indication circuit does.
(When load operates, the lamp is lit, and
when load is turned off, the lamp goes
out.)
• More loads than for one circuit cannot
be controlled.
• There is no leakage current.

1. Over travel (O.T.)
1) When overtravel is too large, life is
shortened due to possible damage to the
mechanism. Please use in the following
appropriate range.
2. Ambient conditions
1) Because these switches are not of
immersion protected construction, their
use in water or oil should be avoided.
Also, locations where water or oil can
normally impinge upon the switch or
where there is an excessive accumula-
tion of dust should be avoided.
2) The use of these switches under the
following conditions should be avoided. If
the following conditions should become
necessary, we recommend consulting us
first.
• Use where there will be direct contact
with organic solvents, strong acids or
alkalis, or direct exposure to their vapors.
• Use where inflammable or corrosive
gases exist.
3) Use within an ambient temperature of
–20 to +60°C –4 to +140°F. (However,
do not allow it to freeze.)
4) In order to maintain the reliability at a
high level under practical conditions of
use, the actual operating conditions
should be checked for the benefit of the
quality of the product.
5) 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.
6) 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.
7) When wiring, do not connect the lead
wires directly to the terminals, but use
the crimp terminals and tighten them to a
torque of 0.39 to 0.59 N·m {4 to 6
kg·cm}.
8) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
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) Do not store in places where organic
gas might be generated or in places of
high dust content or high humidity.
3. Installation
1) Tighten the three cover installation
screws equally. Tightening torque is 0.2
to 0.29 N·m (2 to 3 kg·cm).
2) Avoid having extra cord length pushed
into the cord vent. Any extra length when
wiring should be allowed to rest in its
natural position.

WIRING (unit: mm inch)
1. Insulation distance greater than
6.4 mm
Reinforced plastic with superior electrical
insulation characteristics is used in the
wiring and charging sections. Despite its
compactness, to maintain stable insula-
tion performance, the insulation distance
for each part is greater than 6.4 mm
without using an insulation sheet.
(Complies with UL, CSA, and VDE.)

3. Loose stop terminals used.

4. Lamp holder
1) As shown in the photograph, wrench a
minus-driver in the gap between the
cover and the part of the indicator holder
indicated by the arrow in the direction of
insertion, and raise the lamp a little.
2) After removing the indicator holder,
insert it in the reverse direction, and
push it in until a snap is heard.
3) After changing the direction of the
indicator holder, put the cover on it in
such a way that the spring touches the
top of the terminal screw.
(Unless the spring rests completely on
the terminal screw, distortion of the
spring, failure in lighting of the lamp or
short circuit may result.)
5. Spring type
1) When loads are connected to both
N.O. and N.C. only the indicatin at non-
operation time can be used.
2) Take special care not to damage or
deform the contact spring during change
of indicator holder direction or during
connection work.
3) In the case of VL limit switch with
neon lamp, if the lamp is connected in
series in a 100V circuit, the lamp ceases
to be lighted.
However, for a 200V circuit, up to 2
lamps can be connected in series.
6. Lead type
1) When loads are connected to both
N.O. and N.C. indication can be given on
both N.O. and N.C. sides, but it is impos-
sible to connect the indication circuit to
the load in series and parallel.
