The Siemens 3SE3200-3D is a position switch — the 3SE3 series workhorse for end-of-travel, cam-track, and presence detection on conveyor sections, transfer lines, and machine guarding gates where a mechanical roller-plunger interface is acceptable. The head uses a plunger actuator with a roller, so it tracks cam profiles or sliding door edges without the stem binding. That 10 A figure is the thermal current; for inductive motor-control loads derate per the standard contactor coil inrush — the switch holds the unit on the grid provided you keep the make/break within the AC-15 utilisation category the 3SE3 family is designed for.
Enclosure and wiring
IP67 rating means the switch body and the plunger seal survive washdown spray and airborne dust — fine for food-processing zones, outdoor conveyor gantries, or the wet side of a parts washer. The single cable entry is M20 x 1.5, the standard metric thread for a 10–14 mm cable gland. Dimensions are 30 x 30 x 81 mm, a compact 30 mm square body that fits the same drilled-hole pattern as most European limit switches; you can swap it into an existing 22.5 mm or 30 mm mounting footprint without re-drilling the bracket.
