Siemens 3SE5232-0HU21 is a hinged limit switch with a hollow shaft, part of the SIRIUS 3SE5 family. Encased in a 31 mm plastic enclosure (EN 50047), it carries 1 normally open and 1 normally closed snap-action contact inside a single unit and uses an M20 x 1.5 device connection for wiring. The actuator provides a 10° operating angle, suitable for sensing guard- or door-position on compact machine frames. This hollow-shaft variant is designed for position sensing in automation installations, offering a 31 mm mounting footprint and reliable feedback in standard control circuits.
