IDEM Safety KM-203011 Safety Interlock Switch

Description:

The IDEM KM-203011 Safety Interlock Switch is a tongue-operated safety switch designed to monitor the position of sliding, hinged, or lift-off machine guards in industrial safety systems. It features a robust die-cast aluminum housing with a 90° adjustable head and 2 normally closed (NC) safety contacts plus 2 normally open (NO) auxiliary contacts. The switch provides positive-opening safety contacts and anti-tamper protection, making it suitable for medium- to heavy-duty machine guarding applications.

Applications:

The IDEM KM-203011 Safety Interlock Switch is used on machine guards for CNC equipment, packaging machinery, robotic cells, conveyors, presses, and automated production equipment. It ensures hazardous machinery cannot operate unless the guard is securely closed and immediately interrupts the safety circuit when the actuator key is withdrawn.
