Description:
OPB711 consists of an infrared emitting diode and an NPN silicon phototransistor, mounted “side-by-side” on
parallel axes in a black opaque plastic housing. The OPB712 consists of an infrared emitting diode and an NPN
silicon photodarlington, mounted “side-by-side” on parallel axes in a black plastic housing.
OPB711’s, emitting diode and phototransistor are encapsulated in a filtering epoxy to reduce ambient light noise.
Its phototransistor responds to radiation from the emitter only when a reflective object passes within its field of
view.
OPB712’s emitting diode and photodarlington are encapsulated in a filtering epoxy to reduce ambient light noise.
Its photodarlington responds to radiation from the emitter only when a reflective object passes within its field of
view.
Applications:
 Non-contact reflective object sensor
 Assembly line automation
 Machine automation
 Machine safety
 End of travel sensor
 Door sensor

Notes:
(1) On OPB711, D is the distance from the assembly measurement surface to the reflective surface. On OPB712, D is the distance from
the assembly face to the reflective surface.
(2) Measured using Eastman Kodak neutral white test card with 90% diffuse reflectance as a reflecting surface. Reference: Eastman
Kodak, Catalog #E 152 7795.
(3) Crosstalk (Icx) is the collector current measured with the indicated current in the input diode and with no reflective surface.
(4) All parameters were tested using pulse techniques.
