OPB660N - Slotted Optical Switch

General Description

Each OPB660 slotted optical switch consists of an infrared emitting diode and a NPN silicon phototransistor, combined with an enhanced low current roll-off that improves contrast ratio and provides immunity to background irradiance.

Key Features

  • Non-contact switching.
  • Printed circuit board mounting.
  • Enhanced signal to noise ratio.
  • Gap 0.125” (3.18mm) wide and 0.345” (8.76mm) deep slot.
  • Emitter Aperture 0.05” X 0.06” (1.27mm X 1.52mm),.
  • Sensor Aperture 0.01” X 0.06” (0.25mm X 1.52mm).

Slotted Optical Switch OPB660N, OPB660T Features:  Non-contact switching  Printed circuit board mounting  Enhanced signal to noise ratio  Gap 0.125” (3.18mm) wide and 0.345” (8.76mm) deep slot  Emitter Aperture 0.05” X 0.06” (1.27mm X 1.52mm),  Sensor Aperture 0.01” X 0.06” (0.25mm X 1.52mm) Description: Each OPB660 slotted optical switch consists of an infrared emitting diode and a NPN silicon phototransistor, combined with an enhanced low current roll-off that improves contrast ratio and provides immunity to background irradiance. Housings are made from an opaque grade of injection-molded plastic to minimize sensitivity to both visible and near-infrared light.
