Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Solenoid Key Release, Pushbutton (M-TS-SR-PB)

The M-TS-SR-PB safety door interlock features a solenoid-controlled key that can only be removed once an unlock signal is present. Turning and removing the key releases the actuator and allows access to the hazardous area. The released key (also known as a personnel key) is taken by the operator to reduce the likelihood of an inadvertent start-up occurring. Only when the key is returned can the gate be locked and reset.
