CAUTIONS
1) 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).
2) This switch is not designed for under-
water use. Do not use the unit under-
water.
3) Do not use the switch where it may
come in direct contact with organic sol-
vents, strong acids, strong alkaline liq-
uids or stream, or in atmospheres con-
taining flammable or corrosive gases.
4) To improve reliability during actual
use, it is recommended that the opera-
tion be checked under installation condi-
tions.
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) To protect against entry of foreign
matter from the outside, we recommend
sealing as much as possible using con-
duit connectors.
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.
