CAUTIONS
Die casting case
1) Do not expose HL limit switch to hot
water (over 60°C 140°F) and in a water
vapor environment.
2) Avoid the place where organic sol-
vents, strong acid, strong alkali liquid
and vapor may attach to the products
directly. Prevent using the HL limit switch
in place where inflammable or corrosive
gas will be generated.
3) Do not change the operating position
by bending the actuator.
4) Use within an ambient temperature of
–10 to 80°C. (However, do not allow it to
freeze.)
Plastic case
1) Do not use in water or oil. Do not
place the switch where it is always
exposed to water or dust splash.
2) Do not expose HL limit switch to hot
water (over 60°C 140°F) and in a water
vapor environment.
3) Avoid the place where organic sol-
vents, strong acid, strong alkali liquid
and vapor may attach to the products
directly. Prevent using the HL limit switch
is place where inflammable or corrosive
gas will be generated.
4) Do not change the operating position
by bending the actuator.
5) Use within an ambient temperature of
–10 to 80°C. (However, do not allow it to
freeze.)
5) If OT is too big, the life of limit switch
will be shortened by switching friction.
Use it with enough margin of OT. 70% of
OT standard value will be good.
6) Attach the terminal cover securely to
the body with the metal stop latch to the
projection of the body.
7) Confirmation test in the actual applica-
tion is highly recommended.
8) Do not use the switch in a silicon
atmosphere. Care should be taken
where organic silicon rubber, adhesive,
seling material, oil, grease or lead wire
generates silicon.
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) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
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) Attach the terminal cover securely to
the body to the extent you can identify
the clicking or locking sound.
8) A confirmation test in the actual appli-
cation is highly recommended.
9) 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.
10) 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 generat-
ed, the influence of these environments
may cause deterioration of the rubber
material. Please consult us if you intend
to use a switch in environments such as
these.
11) Avoid use in excessively dusty envi-
ronments where actuator operation
would be hindered.
HL (AZH)
Common for all types
1. There are limits to what type of environment can be tolerated.
This limit switch is designed under the premise that it will be used in a standard industrial device. Accordingly, there are limits as to
what can be tolerated if used outdoors or where water and oil, etc., may get on the device. The following table indicates how much
water and oil can be withstood (classification of protective structure).
2. The internal mechanism will break if the actuator is moved beyond its Total-travel (T.T.). Always use within the T.T.
Protective classification
Testing method
Limits on use
Plastic case (AZH1*)
Die casting case (AZH2*)
IP64
No harmful effect when sprayed with water for 10 minutes from
all angles.
Cannot be used outdoors or in a place where water and oil, etc.,
will continually contact the device.
IP67
Water does not enter product after immersion in water 1m deep
for 30 minutes.
Cannot be used outdoors where it can be rained on directly and
cannot be used submersed in water or in oil, etc.
Note: Although, initially, the protective classification complies under the testing above, due consideration must be taken because great differences may result depending
on factors such as duration of operation, installation method, and environment.
