Product Details

IDEM Kobra INCH Safety Interlock Switches

The Kobra INCH 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 INCH 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. Two versions are available, the INCH-1 and INCH-3, which offer a choice of contact blocks and various actuators to aid installation and maintain durability.
