Machine interlock switch


The Proton is an advanced solenoid interlock switch designed for use on machines for which hazardous conditions persist even after the machine has been switched off. Its heavy-duty solenoid can withstand up to 3000N hold force and energize under a lateral load. The unique mounting holes allow for easy installation on three sides, making it ideal for both hinged and sliding door applications. Its fail-safe design includes a uniquely coded RFID signal (4 billion codes), so only when the actuator plunger and RFID signal are matched will the Proton operate. Up to 30 switches can be connected at the same time.
