Safety Limit Switches (Die-Cast)

Our HLM Safety Limit Switches are designed in a robust, die-cast body and have been designed to be mounted for position sensing of moving applications e.g., guard doors, conveyors, machine beds, elevators.

Options include Roller Plunger, Short Roller Lever, Pin Plunger, Lever Arm – adjustable, Roller Lever – adjustable, Spring Lever and Telescopic Roller Lever – adjustable. All models are available with either slow or snap acting contacts.

Operation of the switches is achieved by a sliding actuation of the moving object to cause deflection of the switch plungers or levers.

For safety applications it is important that the moving object does not pass completely over the switch actuators to either cause damage to the actuator or allow it to return to its original position.
