(12.0 mm) hole. a 12 mm nut is included for each housing. both components is designed to electrically mate with a molex (03-06-2023) connector. the opb856 pair are designed to operate with separation distances between the led and phototransistor up to 12? (30.48 cm). for custom electrical, wire and cabling and connectors are available. contact your local representative or optek for more information. product photo here ordering information OPB856Z 935 nm optical pair part number led peak wavelength sensor connector type transistor use molex 03-06-2023 applications: ? non-contact interruptive object sensing ? assembly line automation ? machine automation ? equipment security ? machine safety rohs housing led - white sensor - black white housing black housing plug molex 03-06-2023 molex 03-06-2023 pin # led pin # phototransistor pin for plug male molex 02-06-6122 female molex 02-06-7104 1 anode 1 emitter 2 cathode 2 collector 1 2 1 2 led phototransistor
