FEATURES
1. Long life
High efficiency coil spring switching
mechanism for long life: More than 107
mechanical operations.
2. Great mechanical strength while
being compact and lightweight
The attachment pitch is 25.4mm
(1.000inch), same as for the Z basic
model microswitch. Also, the outer cover
cap uses a strong plastic with excellent
mechanical characteristics. An M4 bolt
can be used for the attachment.
3. The overtravel (O.T.) is large with
great shock absorption
4. The switch itself is constructed to
be dust-proof and oil resistant
The switch itself is closed flush with the
diaphragm and the compressed rubber
ring, so that the terminal mold type
(epoxy-sealed terminal type) is perfectly
flush with the terminal parts.
TYPICAL APPLICATIONS
Used in sequence control of food pro-
cessing machines, automatic packaging
machines, conveyers, and processors.
Ideal for light industry machinery when
installation pace is limited and a protec-
tive construction is sought.

Terminal Mold Type (Epoxy-Sealed Terminal Type)
The waterproof type (IP64) has its terminals sealed with epoxy resin.
1. Type of product
All the standard type have this epoxy-sealed
terminal types.
2. Appearance
The dimensions are the same as
those of the standard type.
The cord outlet is located either at
the N.C. or COM side.
The cord is 1 m 3.281ft. long.
1. Ambient conditions
1) When the switch is to be used in
places where oil or is abundant, bore a
drain hole in the bottom of the terminal
cover.
2) Avoid places where highly acid or
alkaline fluids are used or high tempera-
tures prevail.
3) This model uses silver terminals.
Therefore, if used at relatively low fre-
quencies for long periods of time, or if
used with very small loads, the oxidiza-
tion that forms on the contact surfaces
will not wear away and eventually cause
improper contact. For such applications,
use limit switches with gold/metal con-
tacts (e.g. VL limit switches) or ones
meant for small loads (e.g. HL limit
switches).
4) This switch is not designed for under-
water use. Do not use the unit under-
water.
5) To improve reliability during actual
use, it is recommended that the opera-
tion be checked under installation condi-
tions.
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) 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.
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.
2.Mounting and wiring
1) Remove the terminal cover with a v
driver. Insert the lead wire through the
knock-out of the terminal cover.
(The terminal cover of the epoxy-sealed
terminal type is filled with resin. It cannot
be removed.)
2) Connect the lead wire to the terminal.
When connecting the terminals with the
fasten lug, those with the insulation
sleeve are recommended.
Tightening torque: 1.18 to 1.47 N·m {12
to 15 kg·cm}
3) The terminal cover can be mounted in
both directions.
• In this case, fasten the terminal cover in
the opposite direction.
• Side mounting
To mount onto a side, use M4 screws
with washers and secure it firmly. The
tightening torque should be 1.18 to 1.47
N·m (12 to 15 kg·cm).
• Panel mounting
(panel mount plunger type)
When installing the panel mounting type
onto a panel, the tightening torque for
the hex. nut should be 7.84 N·m (80
kg·cm).
• For terminal mold types (epoxy-sealed
terminal types), there are two types by
the cord outlet direction; N.C. side and
COM side.
3. Flexible rod
1) Put the detective object to the tip of
plastic part.
2) Avoid pushing the tip of actuating
spring in the direction of axis. In the
places of oil or water splashes and much
dust area, use the limit switch with keep-
ing the actuating spring in the vertical
direction.
