Banner Engineering 67692 SI-LM40MKHFF Safety Interlock Switch Kit

Banner Engineering 67692 SI-LM40MKHFF Safety Interlock Switch Kit is a 40 mm, metal-housed safety interlock designed to guard machine access points. This kit includes an interlock body and inline actuator (SI-QM-SMFA) that is right-angle, flexible, and in-line, with mounting options in Front, Back, Left, or Right positions. The switch provides three poles with two normally closed contacts and one normally open contact, enabling monitored safety circuits for reliable door interlock. The SI-LM40MKHFF kit employs positive-opening safety contacts in accordance with IEC 60947-5-1 to ensure a fail-safe opening of the circuit when the actuator is actuated. The metal housing includes a protective earth terminal on models with metal housings, and the compact enclosure measures roughly 113 x 40 x 42 mm. The 40 mm inline actuator flexes in multiple directions to accommodate misalignment and simplify installation in tight guarding envelopes, making it well-suited for guarding gates on conveyors, presses, and other industrial equipment where a safe stop is required upon door opening. This particular part, 67692, is a specific configuration of Banner's SI-LM40MKH series, optimized for a flexible inline actuation and front/back/side mounting.
