Product Overview

The OPB973N51 is a non-contact Photologic® slotted Optical Switch with open apertures, PCB leads and open-collector inverter logic and output driver. Building from a standard housing with a 0.125-inch (3.18mm) wide slot, the user can specify output logic state, output driver circuit, aperture width, aperture surface and mounting tab locations. The device body is an opaque plastic which minimizes sensitivity to both visible and near-infrared external light sources which may impact operation. Aperture width choices provide different optical resolution for motion sensing.
  • Maximum protection against external light sources
  • Direct TTL, LSTTL, CMOS interface
