IDEM Kobra Explosion Proof Safety Interlock Switches

The Kobra Explosion Proof series from IDEM are tongue operated safety interlock switches that fit to the leading edge of sliding, hinged or lift off machine guards. These safety switches have positively operated switching contacts and a strong tamper resistant key mechanism designed to provide robust position interlock detection for moving guards.
Depending upon the risk assessment for the application, the Kobra Explosion Proof switches can be used independently to provide positively operated contacts to EN60947-5-1 or can be used in combination with any dual channel safety monitoring relays to provide up to Category 4 PLe ISO13849-1 or SIL3 EN62061.
These safety interlock switches have a rugged stainless steel 316 body and have been designed for use in the Food Processing, Pharmaceutical, Packaging and Petro-Chemical industries where explosive environments may be present.
Two versions are available, the K-SS-Ex and KM-SS-Ex, which offer a choice of explosion proof contact blocks and various actuators to aid installation and maintain durability.
