(1.27 mm) lead spacing ? data transfer through plastic fiber optic cable ? isolation voltage 15 kv (opi1280-032), longer versions higher rohs description: each opi1280 consists of a visible red led and a phototransisto r sensor, which are housed in separate opaque molded plastic housings and coupled by plastic fiber optic cable. th e heavy-duty opaque housing shields the optical signal from dust, making this series of devices idea l for dust contaminated environments. the opi1280 series are designed for applications that requir e high voltage isolation between input and output or signal communication over short distances. depending on the length of the fiber optic cable, the emitter does not have to be opticall y in-line with the sensor. the isolation vo ltage is greater than 10 k volts per inch (isolation distance between components) for all versions of the opi1280 . custom electrical, wire and cabling and connectors are availa ble. contact your local repr esentative or optek for more information. applications: ? requiring high voltage isolation between input and output ? electrical isolation in dirty environments ? industrial equipment ? medical equipment 1 4 2 3 pin # led pin # transistor 3 cathode 1 collector 4 anode 2 emitter ordering information part number led peak wavelength lead length OPI1280-018 645 nm opi1280-026 opi1280-032 0.45?
