OPB842W51Z

OPB842W51Z is a slotted optical switch. It provides the design engineer with the flexibility of a custom device from a standard product line. Housings are made from an opaque grade of injection-moulded plastic that minimizes the assembly’s sensitivity to visible and near-infrared ambient radiation. Switching of the phototransistor occurs whenever an opaque object passes through the slot and interrupts the beam. Applications include non-contact interruptive object sensing, assembly line automation, machine automation, equipment security, and machine safety.
