This innovative safety switch with lock function is suitable for process protection thanks to its locking force. Furthermore, a safety level of category 4 PL e (EN ISO 13849-1) can be fulfilled with just one safety switch with lock function and is retained even when connected in series. Reaction time and risk time remain unchanged when connected in series as well. Extensive diagnosis functions enhance system availability and simplify installation and maintenance. Thanks to the electromagnetic operating principle, the safety switches with lock function work in a fully contactless fashion and are thus wear-resistant and easy to clean. Performance Level (EN ISO 13849-1): Cat. 4 PL e. Coding: Standard. Connection: M12 × 1. 8-pin. Temperature Range: -25...55 °C. Locking Force F, guaranteed: 500 N
