HL (AZH) Micro Limit Switch (Discontinued Products)

Cautions For Use

Common for all types

  • 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).

  Plastic case (AZH1*) Die casting case (AZH2*)
Protective
classification
IP64 IP67
Testing method No harmful effect when sprayed with water for 10 minutes from all
angles.
Water does not enter product after immersion in water 1 m 3.281 ft
deep for 30 minutes.
Limits on use Cannot be used outdoors or in a place where water and oil, etc., will
continually contact the device.
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.
  • The internal mechanism will break if the actuator is moved beyond its Total-travel (T.T.). Always use within the T.T.

Die casting case

  • Do not expose HL limit switch to hot water (over 60℃ +140℉) and in a water vapor environment.
  • Avoid the place where organic solvents, 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.
  • Do not change the operating position by bending the actuator.
  • Use within an ambient temperature of –10 to 80℃. +14 to +176℉ (However, do not allow it to freeze.)
  • If O.T. is too big, the life of limit switch will be shortened by switching friction.
    Use it with enough margin of O.T. 70 % of O.T. standard value will be good.
  • Attach the terminal cover securely to the body with the metal stop latch to the projection of the body.
  • Confirmation test in the actual application is highly recommended.
  • 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.
  • This is designed to use inside. 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 cause deterioration of the rubber material and damage for the products.
  • Avoid use in excessively dusty environments where actuator operation would be hindered.

Plastic case

  • Do not use in water or oil.
    Do not place the switch where it is always exposed to water or dust splash.
  • Do not expose HL limit switch to hot water (over 60℃ +140℉) and in a water vapor environment.
  • Avoid the place where organic solvents, 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.
  • Do not change the operating position by bending the actuator.
  • Use within an ambient temperature of –10 to 80℃. +14 to +176℉ (However, do not allow it to freeze.)
  • If O.T. is too big, the life of limit switch will be shortened switching friction. Use it with enough margin of O.T. 70 % of O.T. standard value will be good for use.
  • Attach the terminal cover securely to the body to the extent you can identify the clicking or locking sound.
  • A confirmation test in the actual application is highly recommended.
  • 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.
  • This is designed to use inside. 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 cause deterioration of the rubber material and damage for the products.
  • Avoid use in excessively dusty environments where actuator operation would be hindered.
