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.

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)

Applications:
• Non-contact transmissive object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End of travel sensor
• Door sensor
