Description:

The OPB818 slotted switch consists of an infrared emitting diode and an NPN silicon phototransistor mounted in a

low-cost black plastic housing on opposite sides of a 0.200” (5.080 mm) wide slot. Switching of the phototransistor

occurs whenever an opaque object passes through the slot.

The OPB818Z is designed for direct soldering into PCBoards or for mounting in standard dual-in-line sockets and

has an 0.25” (6.35 mm) deep and 0.20” (5.08 mm) wide slot. The apertures are 0.06” (1.52 mm) in diameter on

both the sensor side (“S”) as well as on the emitter side (“E”).

Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for

more information.
