Slotted Optical Switch
OPB315 Series
Features:
• Lateral package
• Opaque black plastic
• 850 nm wavelength
• Choice of leads or wires
Description:
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 pla ce whenever an opaque object passe s through the slot.
