反射式光电管RP220

OPB732, OPB732W

OPB732 Features: • PC Board Mounting (OPB732) • 24”, 26 AWG Wired with Mounting Tabs (OPB732W) • Non-Contact Infrared Switch • 1” or More Reflective Distance Product Photo Here OPB732W Description:

OPB732 uses an Infrared LED and Phototransistor in a reflective switch configuration. The assembly has either PCBoard through hole pins or 24” [609.6 mm], 26 AWG wires on each terminal and uses an opaque housing to reduce the sensor’s ambient light sensitivity. The emitter and sensor are protected by a clear window, which creates a device that can operate in a dusty environment.

The phototransistor can be configured as a Common Collector or Common Emitter device. When an object is in the reflective path of the device, light from the LED will be reflected back to the housing irradiating the surface (base) of the phototransistor. When Infrared light strikes the phototransistor, the transistor becomes forward biased and is considered to be in the “ON” state, providing an IC(ON) current proportional to the light striking the phototransistor. When the Infrared light from the LED is not reflected to the phototransistor, the phototransistor turns “OFF,” minimizing the IC(ON) current and thus allowing the electrical state to be switched.

Applications:

• Non-Contact Reflective Object

Sensor

• Assembly Line Automation
