RFID safety switch for door monitoring with manipulation protection
The TR4 Direct RFID 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, thereby making electrical installation and service both straightforward and convenient.

TR4 Direct AT A GLANCE
Benefits
-High level of manipulation protection due to individually coded actuator (depending on the type)
-High level of machine availability due to large door offset tolerances and periphery indicator
-High level of reliability due to resistance to shock and vibration
