CAUTIONS
1. Ambient conditions
1) 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 con tact
with organic solvents, strong acids or
alkalis, or direct exposure to their vapors.
Use where inflammable or corrosive
gases exist.
Because these switches are not of
water resistant or immersion-proof con-
struction, their use in water or oil should
be avoided. Also, locations where water
or oil can normally impringe upon the
switch or where there is an excessive
accumulation of dust should be avoided.
2) To improve reliability during actual
use, it is recommended that the opera-
tion be checked under installation condi-
tions.
3) 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.
4) 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.
5) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
6) 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.
2. Mounting and wiring
1) Although SL limit switches have large
over-travel (O.T.), excessive O.T. will
occur wear and change in its characteris-
tics. Specifically, where there is a need
for long life, it is recommended that the
proper O.T. as given below should be
used. Specifically, where there is a need
for long life, it is recommended that the
proper O.T. as given below should be
used.
Within 1 to 3mm .039 to .118inch
2) When the operating object is in the
free condition, force should not be
applied directly to the actuator.
3) Use their own accessories when
mounting and wiring SL limit switches so
as to maintain their own characteristics.
When the SL rubber cover type is used,
there should absolutely be no tension
applied to the cord. If there is the fear
that tension may be applied, the L socket
or socket with cord attached should be
used. The maximum permissible tension
with the above socket use is
98N{10kgF}.
4) The tightening torque when installing
this limit switch should be 1.18 to 1.47
Nm (12 to 15 kgcm).
