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.
Custom electrical, wire, cabling and PCBoard mounted designs are available. Contact your local representative or
OPTEK for more information.
