TT Electronics - Optek Technology OPB315WZ Optical Slotted Sensor

The slotted optical switch in this series combines an infrared LED and a NPN silicon phototransistor mounted opposite each other within a black plastic package featuring a 0.90-inch wide slot. Available in two versions—OPB315L with 0.25-inch leads and OPB315WZ with 24-inch wires—this sensor detects opaque objects passing through its slot. Suitable for non-contact sensing, assembly automation, machine safety, and security applications, it operates reliably across temperature ranges from -40°C to +80°C, providing consistent phototransistor switching response for industrial automation and equipment safety.
