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.

Notes:
(1) Derate Linearly 1.82 mW/^o C above 25^o 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. Reference: Eastman Kodak, Catalog #1257795.
(5) IC(OFF) is the photocurrent measured with current to the input diode and a 5% reflecting
surface.
For RoHS compliant devices add "Z" to the end of the part number: OPB755TZ
