Description
The OPB755T reflective assembly features a phototransistor output designed to decrease low-level light gain while not affecting the high-level light gain.
Available without mounting tabs as OPB755N.
Available with PC Board mountable leads as OPB750 series.
Logic output sensors available in the OPB760/OPB770 series.

100 mW(1) Notes: (1) Derate Linearly 1.
82 mW/o C above 25o C.
(2) All parameters tested using pulse technique.
(3) Methanol or isopropanol are recommended as cleaning agents.
Plastic housing is soluble in
chlorinated hydrocarbons and ketones.
(4) Photocurrent is measured using an Eastman Kodak Neutral White test card having a 90%
diffuse reflectance as a reflecting surface.
