OPI1280-018

Fiber Optic Isolator—Phototransistor Sensor OPI1280 Series Features:  Opaque plas c housings   High noise immunity   IR LED with Phototransistor Output    0.100” (2.54 mm) lead spacing   Data Transfer through plas c fiber op c cable   Isola on voltage 15 KV (OPI1280‐032), Longer versions higher Description: Each OPI1280 consists of a IR LED and a Phototransistor sensor, which are housed in separate opaque molded plas c housings and coupled by plas c fiber op c cable. The heavy‐duty opaque housing shields the op cal signal from dust, making this series of devices ideal for dust contaminated environments. The OPI1280 series are designed for applica ons that require high voltage isola on between input and output or signal communica on over short distances. Depending on the length of the fiber op c cable, the emi er does not have to be op cally in‐line with the sensor. The isola on voltage is greater than 10 K volts per inch (Isola on distance between components) for all versions of the OPI1280.   Custom electrical, wire and cabling and connectors are available. Contact your local representa ve or OPTEK for more informa on. Applications: Ordering Information  Requiring High Voltage isola on between input and output  Electrical isola on in dirty environments  Industrial equipment  Medical equipment 3 4 RoHS 1 2 Part Number OPI1280‐018 Lead Spacing ±.08” [2] 0.88” [22.4 mm] Device Length ±.08” [2] 1.22” [31 mm] OPI1280‐026 1.20” [30.5 mm] 1.53” [38.9 mm] 1.18” [30 mm] OPI1280‐032 1.42” [36.1 mm] 1.76” [44.7 mm] 1.40” [35.6 mm] OPI1280‐066 2.78” [70.6 mm] 3.11” [79 mm] 2.76” [70 mm] PIN # FUNCTION 1 Anode 2 Cathode 3 Collector 4 Emitter LED Peak Wavelength Lead Length 890 nm 0.43” [11 mm] Tolerances are ± .010” [.25] unless otherwise stated dimensions are in inches [millimeters] General Note TT Electronics reserves the right to make changes in product specifica on without no ce or liability.
