WIRING
1. Insulation distance greater than
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.)
2. Includes ground terminal
3. Loose stop terminals used.
Applicable wire
CAUTIONS
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
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.
