LIMIT SWITCHES
SL (AZ3) Micro
Limit Switches
6. Long life
By combining the excellent reliability and
solvent proofing of the FS-T microswitch
with the L shape spring, we have
achieved a unit with both long life and
high reliability (electrical life: 10
5
mechanical life: 10
7
7. Built-in safety features and excel-
lent environment proofing
The case uses 66 nylon glass fiber the
doubly protect the switch. Also, the body
and cap have been ultrasonically weld-
ed, creating a flush construction except
for the terminals. Moreover, by adding a
dedicated socket, the construction is
drip-proof, dust-proof, and dirt-proof, cre-
ating a flush construction for the unit as a
whole including the terminals.
Rubber cover type: Equivalent to IP60
Socket with cord type: Equivalent to IP64
Quickly upgraded to limit switches with lamps by mounting an LED lamp socket.
2. A lamp can be easily added for
operations checks
An exposed terminal type model com-
bined with a socket with cord for the
built-in LED lamp (sold separately) easily
become a limit switch with lamp.
Convenient for maintenance checks
such as operations checks.

FEATURES
1. Subminiature limit switch
Managed to miniaturize the comparative
bulk with high density mountings in the
equipment’s detector to approximately
1/3 of our own ML limit switches, or
approximately 1/1.6 of the Z model
microswitch.
Approx. 1/3
r
ML
SL
3. Operates with a light force
Comes in two types: O.F. is a maximum
of 1.18N {120gf} (light force model) and
light force commensurate to the
microswitch.
4. Terminal uses both solder and tab
(#110)
5. Achieves stroke tolerance
(O.T./T.T.) of 0.67
Plenty of scope for position fixing with
long life.
Because of the optimum design of the
built-in limit switch and the original L-
model spring for use in O.T. absorption,
the total travel range has been enlarged,
and both position fixing and the unit’s
lifespan have been improved a level.
Stroke range: 3 times more than the ML limit
TYPICAL APPLICATIONS
Dust proofing and oil resistance require-
ment.

CONNECTION METHOD FOR RUBBER COVER
1) Remove the rubber cover from the
limit switch.
3) Connect lead wire to the receptacle
terminals (#110) with insulating sleeve
provided and insert it into the terminal of
limt switch. (The lead wire can directly be
soldered to the terminals without using
receptacle terminals)
4) Push the rubber cover securely over
the terminals.
2) After stripping the sheath from the
appropriate cord (refer to table on the
right) and removing the covering of the
lead wires, insert the cord into the rubber
cover.

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
N·m (12 to 15 kg·cm).
