Reflective Object Sensor
Type OPB750T
Features
• High contrast ratio, 1000 to 1
minimum
• Printed circuit board mount
• Low cost plastic housing
Description
The OPB750T 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
OPB750N.
Available with 12", 26 AWG wire leads as
OPB750/OPB755 series. Photologic®
output sensors available in
OPB760/OPB770 series.

Notes:
(1) Derate Linearly 1.67 mW/o C above 25o C.
(2) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering.
(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.
(6) IC(OFF) is the photocurrent measured with current to the input diode and a 5% reflecting
surface.
