Description:
The OPB609 consists 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 such as paper, labels, or anything with a matte finish.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK

To avoid stress cracking, we suggest using ND
Industries’ Vibra-Tite for thread-locking.
Machine safety
Vibra-Tite evaporates fast without causing
structural failure in OPTEK’s molded plastics.
