OPB200

OPB200 is a slotted optical switch. It contains an infrared LED (890nm) and a phototransistor paired in a plastic housing. The housing is an opaque grade of injection-molded plastic, which minimizes the assembly’s sensitivity to visible and near infrared radiation. Each device has approximately 0.060” [1.52mm] diameter lenses providing the versatility necessary for general switching applications. The output phototransistor ON state conducts current (IC(ON)) when no object is in the slot. The output switches to the OFF state when a device interrupts the light beam from the emitter (LED) to the phototransistor. The phototransistor can acknowledge light between 400nm and 1100nm with optimum response in the 880nm range. It is used in applications such as non-contact interruptive object sensing, assembly line automation, machine automation, equipment security, machine safety.
