Reflective Object Sensor
OPB706A, OPB706B, OPB706C
OPB707A, OPB707B, OPB707C
Features:
• Choice of Phototransistor (OPB706) or
Photodarlington (OPB707) output
Product Photo Here
• Unfocused for sensing diffuse surface
• Low cost plastic housing
• Designed for use with PCBoards or connectors
Description:
The OPB706 consists of an infrared Light Emitting Diode (LED) and an NPN silicon Phototransistor mounted
“side-by-side” on parallel axes in a black plastic housing. The OPB707 consists of an infrared LED and an NPN
silicon Photodarlington mounted “side-by-side” on parallel axes in a black plastic housing.
On both OPB706 and OPB707, the LED and Phototransistor / Photodarlington are molded using dark infrared
transmissive plastic to reduce ambient light noise. The Phototransistor / Photodarlington responds to light from
the emitter when a reflective object passes within its field of view of the device.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK
for more information.

Notes:
(1) Crosstalk (ICX) is the collector current measured with the indicated current in the input diode and with no reflecting surface.
(2) The distance from the assembly face to the reflective surface is “d”.
(3) Measured using Eastman Kodak neutral white test card with 90% diffuse reflectance as a reflecting surface. Reference:
Eastman Kodak, Catalog #E 152 7795.
(4) Lower curve is a calculated worst case condition rather than the conventional -2 Ω limit.
(5) All parameters tested using pulse techniques.
