OPB730 TT Electronics

F-Package Choice of phototransistor or photodarlington output Unfocused for sensing diuff se surface Mounted on standard TO-72 header Available in clear encapsulating epoxy (OPB710, OPB730) Filtered to reduce the eeff ct of visible or fluorescent light (OPB710F, OPB730F) OPB710 and OPB710F consist of a gallium arsenide infrared emitting diode and an NPN silicon phototransistor. OPB730 and OPB730F consist of a gallium arsenide infrared emitting diode and an NPN silicon photodarlington. On each sensor, the emitting diode and detector are mounted side -by-side on parallel axes in a standard TO-72 header. A black plastic sleeve is attached and filled with encapsulating epoxy to cover the emitter and detector. The OPB710F and OPB730F (F versions) have a filtering material added to the epoxy to reduce the eeff ct of ambient light. The package contains an internal barrier which prevents diode emissions from reaching the sensor directly. Custom electrical, wire and cabling and connectors are available.

(4) Measured using Eastman Kodak neutral white test card having 90% diffuse reefl ctance located .250 inch (6.35 mm) from the face of the OPB710/ OPB730. Reference: Eastman Kodak, Catalog E 152 7795. (5) Crosstalk (ICX) is the collector current measured with the indicated current on the input diode and with no reefl cngti surfa ce. Ambient light is ex- cluded with a black box.
