Reflective Object Sensor

Optek Technology 

Product Bulletin OPB750N

June 1996

Reflective Object Sensor

Type OPB750N

Features

• High contrast ratio 1000 to 1 minimum

• Printed circuit board mount

• Low cost plastic housing

Description

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.

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.
