The SIEMENS 3SE5112-0BD02 is a 40 mm position switch in a metal enclosure designed for reliable mechanical position sensing in industrial control systems. It provides one normally open and one normally closed slow-action contact, allowing straightforward changeover logic and safe circuit control. The device connects via a single M20 x 1.5 gland and features a 13 mm stainless steel roller plunger that withstands repeated actuation while minimizing wear. Built to the EN 50041 footprint, this switch fits standard mounting arrangements and is suitable for conveyor, door, or machine-guard applications where precise, repeatable position feedback is required.
