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.

Housings are made from an opaque grade of injection-molded plastic to minimize sensitivity to both visible and near-infrared light.

Applications:  Non-contact transmissive object sensor  Assembly line automation  Machine automation  Machine safety Part  End of travel sensor Number  Door sensor OPB660N OPB660T LED Peak Wavelength 890 nm Slot Width / Aperture Lead Length / Sensor Depth Emitter/Sensor Spacing Rbe Transistor 0.125" / 0.345” 0.05" / 0.01" 0.100" / 0.320" (MIN) 23 14 Pin # 1 2 LED Anode Cathode Pin # Transistor 3 Collector 4 Emitter [ MILLIMETERS] DIMENSIONS ARE IN: INCHES General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
