Features:

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

for more information.

To avoid stress cracking, we suggest using ND

Industries’ Vibra-Tite for thread-locking.
