(1.27 mm) lead spacing ? data transfer through plastic fiber optic cable ? isolation voltage 15 kv (opi1290-032), longer versions higher rohs description: each opi1290 consists of a visible red led and a photologic ? totem-pole output sensor, which are housed in separate opaque molded plastic housings and coupled by plastic fiber optic cable. the heavy-duty opaque housing shields the optical signal from dust, making this series of devices ideal for dust contaminated environments. the opi1290 series are designed for applications that require hi gh 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 opi1290 . custom electrical, wire and cabling and connectors are availa ble. contact your local repr esentative or optek for more information. pin # led 1 anode 2 cathode 3 v cc 4 output 5 ground device length anode cathode v cc output ground ordering information part number led peak wavelength lead length OPI1290-018 645 nm opi1290-026 opi1290-032 0.45?
