The TR4 Direct transponder safety switch is used for applications where a high level of manipulation protection is required.
TR4 Direct has monitored semiconductor outputs (OSSD) and can therefore be connected directly to a safety controller. The safety switch is only released if a valid actuator is located within the response range of the TR4 Direct. Two actuation principles are available: For universally coded variants, any universally coded actuator can be located in the response range. For uniquely coded variants, only the uniquely coded actuator that has been taught in with the matching code stored may be located within the response range. Up to 30 safety switches, all with LED status indicators, can be connected in series without any problems, making electrical installation and service both straightforward and convenient.
