OPB755TAZ
OPB755TZ
Description:
Each sensor in the OPB750 and OPB755 series has a reflective assembly that features a Light
Emitting Diode (LED) and phototransistor output designed to decrease low-level light, while not
affecting the high-level light gain.
The OPB750N and OPB750T devices have are designed for PCBoard mounting with 0.40” (10 mm)
length leads. OPB755NZ, OPB755TZ and OPB755TAZ assemblies are designed for remote
mounting. The OPB755NZ and OPB755TZ have 12” (305 mm) UL rated wire, 26 AWG wire leads
that terminate into an AMP # 3-640442-5 connector. The OPB755TAZ has 24” (610 mm) UL rated
wire, 26 AWG leads. The OPB750T, OPB755TZ and OPB755TAZ have two mounting tabs while
the OPB750N and OPB755NZ have no mounting tabs.
Photologic® output versions are available with the OPB760 and OPB770 series.
Custom electrical, wire and cabling and connectors are available. Contact your local representative
or OPTEK for more information.

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/° C above 25° C.
(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 90% diffuse reflectance as a reflecting
surface. Reference: Eastman Kodak, Catalog #E 152 7795.
