S12-2 Emitter/Receiver Pair

S12-2-Emmitter-Reciever-Pair_03

Overview

An economical emitter and receiver pair, the S12-2 features a wide beam pattern in a small compact housing unit.

  • Small 12 mm (0.47 inch) diameter tubular opposed mode sensor pair
  • Fully threaded barrel allows easy mounting to bracket or panel with included M12 nuts
  • Easy-to-see status LED indicators for Power ON, Output Overload, Signal Received, and Marginal Signal
  • Wide beam pattern makes sensor alignment easy at long ranges
  • Emitter beam inhibit to verify normal sensor operation before motion
  • Robust epoxy encapsulated electronics for reliable use in industrial environments
