SB12 Series


Small, easy-to-mount opposed mode sensor pairs that are cost effective for large volume applications.

  • Easy-to-mount; no brackets required — choice of threaded models with retaining nut or unique snap-in models
  • Small, 12.7 mm diameter opposed mode sensor pair
  • Cost effective for large volume applications
  • Narrow effective beam allows for multiple sensors in close proximity
  • LED status indicators for Power ON, Output Overload, Signal Received and Marginal Signal
  • Light Operate (LO) or Dark Operate (DO), depending on model
