Reflective Object Sensor
OPB609 Series
Features:
•
•
•
•
OP609 emitter (940 nm IR-LED)
Unfocused for sensing diffuse surface
Low-cost plastic housing
High-speed phototransistor output
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.
Applications:

Non-contact reflective object sensor
Assembly line automation
CONTAINS POLYSULFONE
Machine automation
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.
