(10 mm) length leads. opb755nz, opb755tz and opb755taz assemblies are designed for remote mounting. the opb755nz and opb755tz have 12? (305 mm) ul rate d 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. features: ? high contrast ratio (1,000 :1 minimum) ? low cost plastic housing ? pcboard mount (opb750n, OPB750T) ? 12?
