Interlock switch targets machine safety

New device designed for use on machines where hazardous conditions persist

Norstat now offers an advanced solenoid interlock switch that has been designed for use on machines where hazardous conditions persist, even after the machine has been switched off.

“The robust design and heavy-duty solenoid of the Proton from Mechan Controls can withstand up to 3000N hold force and energise under a lateral load. The internal specifications meet the requirements for CAT4, SIL3 and will maintain PL-e, even when connected in series,” advises Norstat.

The mounting holes allow for easy installation on three sides, “making it ideal for both hinged and sliding door applications”.

Fail-safe design

The spring-loaded actuator means the Proton excels at misalignment tolerances, it is further stated. “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.”

Each switch includes two OSSD inputs and two OSSD outputs that are designed for series connection. Up to a maximum of 30 switches can be connected at the same time. The Proton includes six LEDs, three on each side, that display the same data and provide visual diagnostics for all states of the device.
