Euchner 121579 CET3-AP-CRA-CH-50X-SA Safety Switch 11 W (90°)

Product Description

Euchner 121579 is a CET3-AP series transponder-coded safety switch with guard locking that uses RFID and a closed-circuit current principle (power to unlock). The device provides two redundant semiconductor safety outputs with internal monitoring, monitoring outputs for guard locking and door position, and an M12 8-pin plug connector. It meets Category 4 / PL e and SIL 3 safety requirements and is rated IP67 for harsh environments.

• Two redundant semiconductor safety outputs with internal monitoring; monitoring outputs for guard locking (OUT) and door position (OUT D).
• Guard locking via closed-circuit current principle (power to unlock), solenoid power 11 W, locking force up to 6500 N; head/approach adjustable in 90° steps.
• Operating electronics 24 V DC (-15%/+15%), solenoid 24 V DC (-15%/+10%), M12 8-pin connector, IP67, die-cast aluminum housing with stainless steel ramp.

Product Highlights

Transponder-coded RFID safety interlock with guard locking, Category 4 / PL e compliance, SIL 3, M12 8-pin connector, IP67.
