Euchner 126763 CET4-AP-CRA-AH-50X-SI-C2438 24 V DC 11 W (90 deg) 126763

Product Description

Euchner 126763 is a transponder-coded safety switch (CET4-AP series) with integrated guard locking and evaluation electronics. The device provides a 24 V DC solenoid (11 W) for power-to-lock operation, two redundant semiconductor safety outputs with internal monitoring, and a door position monitoring output. It connects via two M12 5-pin plug connectors and is rated for Category 4 / PL e and SIL 3 safety applications in industrial environments.

• Transponder-coded (Unicode/Multicode) actuator recognition; actuator sold separately and only taught-in actuators are detected
• Guard locking by open-circuit current principle with 24 V DC solenoid (11 W, 100% duty cycle) and locking force up to 6500 N
• Two redundant p-switching semiconductor safety outputs (short-circuit-proof), door monitoring output OUT D, LED status and diagnostics, IP67

Product Highlights

Transponder-coded guard-locking safety switch, 24 V DC 11 W solenoid, 2 x M12 5-pin connectors, Category 4 / PL e, IP67
