Comitronic-BTI OPTO2S Polyamide Non contact coded safety switches - Position control for doors / casings on hazardous machinery


  • Coded ACOTOM®
  • Easily replaces mechanical safety switches
  • High switching capacity
  • LED status display of the correct code recognition


The OPTO2S FURTIF is an electromechanical sensor of category 1, non contact, coded and autonomous, using our process ACOTOM2 . It allows the detection of the opening of guard-doors on dangerous machines. Composed of two elements in polycarbonate, one named the "transmitter", the other named "the receiver", it provides two NO contacts lines free of voltage protected by a 250mA fast fuse. It reaches safety category 4 when it is connected to a safety relay.
