Non Contact Interlock Switches

Non-contact interlock switches provide reliable guard door monitoring without mechanical engagement—enabling flexible machine design while maintaining stringent safety integrity. Utilizing inductive or magnetic sensing technology, these devices detect actuator presence through physical barriers, allowing for misalignment tolerance, vibration resistance, and sealed construction impervious to contamination. Ideal for high-pressure washdown environments, dusty production lines, and applications requiring frequent access where mechanical wear or debris accumulation would compromise traditional tongue-operated interlocks. Engineered to SIL 3 / PLe performance levels, they deliver consistent safety function with minimal maintenance demands and extended operational life.
