Product Overview

The OPB880 series Phototransistor Sensor that provides the flexibility of a custom device from a standard product line. Building from a standard housing with a wide slot, user can choose aperture width, opaque or IR transmissive housing shell material, PCBoard lead spacing or wires and mounting tab configuration. Housings are made from an opaque grade of injection-molded plastic to minimize sensitivity to both visible and near-infrared light. Discrete shells exposed on the parallel faces inside each device's throat are made from either IR transmissive plastic (for applications where dust protection is needed) or from opaque plastic with aperture openings (for applications that require maximum protection against ambient light). The series have 26 AWG, UL approved wires connected directly to the device for remote sensing applications.
  • 0.125" (3.175mm) Slot width
  • Choice of aperture (0.05 or 0.01" width)
  • Choice of opaque or IR transmissive shell material
  • Choice of mounting configurations
  • Choice of lead spacing or wires
