Banner Engineering SI-LS42DMJ Safety Interlock Switch

The SI-LS42DMJ is Banner Engineering's locking-style safety interlock switch with a solenoid locking mechanism, designed for guarding access doors on safety-critical machinery. It operates from 24 V AC/DC (solenoid voltage) and offers a contact configuration of 3 NC plus 1 NC, enabling wiring flexibility in safety circuits. Encased in a thermoplastic housing measuring 170 × 43 × 45 mm with an IP67 rating, the device uses a Power Lock locking mechanism to secure the guard and prevent accidental door opening while the system is energized. This interlock is part of Banner's SI-LS42 series of safety interlock switches, providing a robust solution for machine safety interlocks in industrial environments.
