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 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. Reference: Eastman Kodak, Catalog #1257795.

(5) IC(OFF) is the photocurrent measured with current to the input diode and a 5% reflecting

surface.
