Siemens 3SE22836GA43 Safety Relay 24V DC Coil

Siemens 3SE22836GA43 is a hinge‑mounted safety switch from the Sirius 3SE2 family, designed to guard doors and access points on industrial equipment and interrupt the safety circuit if a guard is opened. It offers three normally closed (NC) auxiliary contacts in a 3NC configuration, enabling multiple safety circuits within a single device. The unit is housed in a molded-plastic enclosure with an aluminum hinge and a 4° actuating angle, which supports reliable actuation and compact integration on standard guarding setups. Two cable entries are provided at M20 x 1.5 for wiring flexibility, and the hardware is suitable for mounting on 40 mm profile guarding systems. Electrical ratings include a control circuit at 24 V DC with Ie DC‑13 up to 1 A; switching loads can be handled up to 125 VAC or 24 V DC, with a maximum AC switching capacity around 4.2 A at 230 VAC. This hinge switch is intended for use with safety controllers or safety PLCs to implement guarded‑start and interlock applications in equipment such as presses, conveyors, and robotic work cells, delivering a compact, reliable interlock solution for safety circuits.
