Comitronic-BTI FURTIF 7SSR24V Non contact coded safety switches - Stand alone operation


  • Coded ACOTOM®
  • CuNi housing M30x1.5
  • LED status display of the correct code recognition
  • Cylindrical design


The 7SSR24V is a coded electronic autonomous sensor using our process ACOTOM allowing to detects the opening of the mobile protectors on dangerous machines. This switch is uncheatable. Housing in two elements in nickel and copper alloy, the transmitter and the receiver which supplies two NO contact lines free of potential and isolated from the decoding system which guarantees more safety, and an auxiliary NC PNP contact.
