The GS series safety interlock switch has a compact and robust design and forgiving and stable alignment. It can be integrated into any safety system. A redesigned actuator allows for easier door closure and the ability to maintain door closure over time even when doors or gates sag or machine vibration occurs. This feature eliminates unnecessary machine stoppages. Large LED status indicators change colors depending on door status, allowing personnel to check from a distance whether the door is open or closed. A small footprint enables direct and flexible mounting, increasing location options.
