2702972, Phoenix Contact PSR-CT-C-SEN-1-8 RFID Safety Non Contact Switch, PBT, 24 V dc, Выключатель

Proximity safety circuit, unicode sensor with RFID coding, model 4, automatic or manual start, integrated diagnostics, 24 V DC supply, M12 connector.
The PSR-CT safety circuit consists of a combination of a PSR-CT-...-SEN-1-8 sensor with varying coding types and a coded PSR-CT-C-ACT actuator. It provides maximum tamper protection and the highest level of safety. The PSR-CT safety circuit is available with the following types of coding:
Fixcode: For the sensor to detect the actuator, the actuator must first be associated with the sensor via a learning process. The learning process can only be completed once. The sensor and actuator are then permanently assigned to each other by their coding. Safety circuits with fixcode evaluation achieve a high coding level.
Unicode: For the sensor to detect the actuator, the actuator must first be assigned to the sensor via a learning process. The learning process for a new actuator can be repeated any number of times. The sensor only detects the last learned actuator. Safety circuits with unicode evaluation achieve a high coding level.
Multicode: The sensor detects every actuator of the approved type. No specific actuator code can be assigned. Safety circuits with multicode evaluation achieve a low coding level.
