CTP-AP Safety Switch


CTP Safety Switches are used to monitor the position of movable machine guarding by means of Inductive Coding. The safety switch CTP with guard locking is based on the proven transponder principle. The CTP is a narrow profile thermoplastic housing with integrated evaluation module making it a complete package. These switches feature an inductive read head with built-in evaluation and a digitally coded actuator.
