The SIEMENS 3SE5112-0LF01 is a position switch in a metal enclosure with a 40 mm form factor, built to EN 50041 mounting dimensions for reliable machine integration. Designed for direct device connection via a single M20 x 1.5 entry, it provides one normally open and two normally closed quick-action contacts for clear, repeatable switching. The angular roller lever with a 22 mm plastic roller delivers precise actuation and smooth operation on moving parts. This compact, panel-mount switch is suited for conveyor stops, safety interlocks, or position sensing where a sturdy enclosure and defined connection standard are required.
