Transponder-coded safety switch CET with guard locking

Product catalog summary
Overview: The CET transponder-coded safety switch combines mechanical guard locking with electronic coded actuators, designed for securing safety doors in machines and installations. It is robust, versatile, and suitable for harsh environments, offering a high locking force of 6,500 N.
Specifications: The CET features a robust metal housing, high locking force, and is suitable for large and heavy doors. It offers a high degree of protection (IP67) and is designed for easy installation with minimal wiring effort.
Functionality: The CET is mounted on the fixed part of the safety guard, with the actuator on the moving part. It uses a spring-loaded plunger and transponder to detect closed and locked positions, releasing the safety circuit when locked. It supports Unicode and Multicode coding for different security needs.
Compliance and Safety: The CET meets EN ISO 13849 and EN 14119 standards, achieving Performance Level e (PL e) and Category 4 with a single switch. It provides effective protection against tampering and allows for mechanical key release and emergency unlocking.
Guard Locking Types: The CET offers mechanical guard locking (spring force) and electrical guard locking (solenoid force), with options for door monitoring output and simple bus connection via AS-Interface.
Accessories and Integration: A comprehensive range of accessories is available, including mounting plates, unlocking aids, and various bolt systems. The CET system families offer different connection and wiring concepts tailored to customer requirements.
Advantages: The CET provides a combination of mechanical and transponder technology, high locking force, robust construction, and suitability for heavy doors and harsh environments. It ensures process and personnel protection, even in overtravelling machine movements.

Transponder-coded safety switch CET with guard locking-3

n Types of guard locking Two different types of guard locking are used with the CET. n echanical guard locking: guard locking by spring force. Release by applying voltage to the guard locking soleM noid (closed-circuit current principle). n lectrical guard locking: guard locking by solenoid force. Activation of guard locking by applying voltage to the E guard locking solenoid (open-circuit current principle). n Door monitoring output (available for variants with integrated evaluation electronics) This allows the position of the safety door (open/closed) to be recognized. n Simple bus connection...
