Description:
The OPB609consists of an 940 nm, Light Emitting Diode (LED) and an NPN silicon Phototransistor, which are
mounted “side-by-side” on parallel axes in a black opaque plastic housing. This unfocused reflective object
sensor is ideal for detection of diffuse materials suchas paper, labels, or anything with a matte finish.

FEATUREs:
• OP609 emitter (940 nm IR-LED)
• Unfocused for sensing diffuse surface
• Low-cost plastic housing
• High-speed phototransistor output

APPLICATIONs:
• Non-contact reflective object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End-of-travel sensor
• Door sensor
• Edge detection
• Paper jam detection
• Mark detection
