    To keep your environments free of contaminants, the magnet is encapsulated so it won't release particles when it meets the strike plate. Magnetic force holds doors closed.
    Note: Maximum pull-strength rating given is based on installation with the furnished strike plate; pull strength may be different based on the application.
    Pivoting Strike Plate—On latches with a pivoting strike plate, the strike plate moves for better contact with the magnetic latch.

    Stainless Steel Housing

    Prevent accidental bumps or vibration from triggering these safety switches unnecessarily—a strong magnet maintains the RFID signal between the actuator and switch until it's intentionally opened. Also known as interlock switches, they automatically cut power when you open an access door, interrupting the signal, then restore power when the door is closed, and the switch and actuator meet. They're designed to mount on a frame and a door, gate, or window. Use them in many ways—from turning off a machine-operated saw when you open the protective window to powering down robotic arms when someone enters the partitioned area. The LED indicator shows that your switch is on and whether it’s actuated.
    Unique RFID Code—Switches with a unique RFID code are only compatible with their own actuator, so they’re difficult to tamper with.
    IP69K Enclosure Rating—IP69K rated switches protect against high-pressure, high-temperature washdowns.
    Number of Safety Outputs—The number of safety outputs, also known as output signal switching devices (OSSDs), tells you how many machines you can control. Each output has a pair of signals that shut down a single machine—if one signal fails, the other takes over as a failsafe.
