The OPB750N reflective assembly
features a phototransistor output
designed to decrease low-level light gain
while not affecting the high-level light
gain. Available with two mounting tabs as
OPB750T.
Available with 12", 26 AWG wire leads as
OPB755 series. Photologic
output
sensors available in OPB760/OPB770
series.

(3) All parameters tested using pulse technique.
(4) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in
chlorinated hydrocarbons and ketones.
(5) Photocurrent is measured using an Eastman Kodak Neutral White test card having a 90%
diffuse reflectance as a reflecting surface. Reference: Eastman Kodak, Catalog #1257795.
