- 850 nm wavelength 

- Choice of  leads or wires 

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.
