Each slotted optical switch in this series consists of an infrared emitting diode (LED) and a NPN silicon phototransistor

mounted on opposite sides of a 0.90” (22.9 mm) wide slot in an opaque black plastic package.

The OPB315L has 0.25” minimum leads, while the OPB315WZ has a minimum of 24” (610 mm) 26 AWG wires.

Phototransistor switching takes place whenever an opaque object passes through the slot.
