the opb960/ 970/ 980/ 990 series of non - contact photologic ? sloted optcal switches provides fexibility in meetng applicaton specifc requirements for the design engineer. building from a standard housing with a 0.125 (3.18mm) wide slot, the user can specify output logic state, output driver circuit, aperture width, aperture surface and mountng tab locatons. furthermore, an opton of wire or pcb leads allows electrical interface fexibility. the device body is an opaque plastc which minimizes sensitvity to both visible and near - infrared external light sources which may impact operaton. aperture width choices provide diferent optcal resoluton for moton sensing. a covered aperture provides dust protecton, while an open aperture provides maximum protecton against external light sources. electrical operaton is over a wide supply voltage range. led emissions are near - infrared (850 940nm). detector digital output logic choices of bufer or inverter with totem - pole or open - collector driver circuit simplify interface for various electrical requirements. custom electrical, wire and cabling services are available. contact your local representatve or optek for more informaton. compliant to eu rohs directve 2002/95/ec ? choice of logic and output driver circuits ? choice of aperture size, covered or open ? wire or pcb leads ? choice of mountng features ? direct ttl, lsttl, cmos interface rohs ? speed and directon indicaton ? rotary encoders ? mechanical switch replacement ? mechanical limit indicaton ? printers - top of form, end of travel, home positon. ? sliding door automotve and lif gate applicatons optek assembly photologic ? sensor family slot aperture surface and lead options: 6 covered (apertures not visible), pcb leads 7 open (apertures visible), pcb leads 8 covered (apertures not visible), wires 9 open (apertures visible), wires logic and output driver types: 0 buffer totem - pole 1 buffer open - collector 2 inverter totem - pole 3 inverter open - collector z = wires only, none for pcb leads aperture width guide options: 55, 51, 11 ( see aperture width guide ) mounting tab location: l emitter n none p sensor t both (two mounting tabs) opb 9xx x xx x logic type input led output log- ic state buffer off low = 0 inverter off high = 1 part number guide
