Please find the complete data in the user's documentation. Our General Terms of Use for Downloads are valid (http://phoenixcontact.com/download) Proximity safety circuit up to Cat. 4, PL e (EN ISO 13849), SIL 3 (IEC 61508), fixcode sensor with RFID coding, model 4 (EN ISO 14119), automatic or manual start, integrated diagnostics, 24 V DC supply, IP69K, M12 connector The figure shows a product version of the article ## Product Description 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 in accordance with EN ISO 14119. 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. ## Your advantages Integrated reset function on the switch - 4 actuation settings, 3 travel directions - Tamper protection via RFID transponder technology - Rapid diagnostics, thanks to comprehensive status information - Consistent M12 connection technology for convenient installation - Safe series connection in accordance with EN ISO 14119 - Flexible use, thanks to compact design - Safe, cost-effective complete solution Key Commercial Data Packing unit 1 pc ~~a GO~~ GTIN ~~po~~ GTIN 4055626447032 ~~a _ (4°055626°447032~~ Weight per Piece (excluding packing) 41.300 g ~~GO~~ 02/27/2020 Page 1 / 9 https://www.phoenixcontact.com/gb/products/2702976 ## Safety switch sensor - PSR-CT-F-SEN-1-8 - 2702976 |Custom tariff number<br>85365019<br>Country of origin<br>Germany<br>~~<<~~| |---| |Technical data| |Dimensions| |Width<br>26.5 mm<br>Height<br>40 mm<br>Depth<br>18 mm<br>~~——~~| |Ambient conditions| |Ambient temperature (operation)<br>-25 °C ... 55 °C<br>Ambient temperature (storage/transport)<br>-40 °C ... 70 °C<br>~~——————~~| |Power supply| |Supply voltage|24 V DC ±15 % (PELV, controlled, residual ripple < 5% )| |---|---| |Current consumption|max. 40 mA| |Protection|min. 0.25 A (to be performed externally)| ||max. 8 A (to be performed externally)| ## Alarm outputs |Designation|DGN| |---|---| |Output description|p-wired| |Number of outputs|1| |Short-circuit-proof|yes| |Output voltage|min.
