| Fiber Optic Isolator--Phototransistor Sensor OPI1280 Series Features: * * * * * * Opaque plastic housings High noise immunity Visible Red LED with Phototranisitor Output 0.05" (1.27 mm) lead spacing Data Transfer through plastic fiber optic cable Isolation voltage 15 KV (OPI1280-032), Longer versions higher Description: Each OPI1280 consists of a visible Red LED and a Phototransistor 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 OPI1280 series are designed for applications that require 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 optically in-line with the sensor. The isolation voltage 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 available. Contact your local representative or OPTEK for more information. Ordering Information Applications: * Requiring High Voltage isolation between input and output * Electrical isolation in dirty environments * Industrial equipment * Medical equipment Part Number OPI1280-018 OPI1280-026 OPI1280-032 OPI1280-040 OPI1280-066 OPI1280-080 Isolation Distance 0.71" [18 mm] 1.02" [26 mm] 1.26" [32 mm] 1.57" [40 mm] 2.60" [66 mm] 3.15" [80 mm] Device Length 1.26" [32.0 mm] 1.57" [40.0 mm] 1.80" [45.8 mm] 2.12" [53.8 mm] 3.15" [80.0 mm] 3.69" [93.8 mm] LED Peak Wavelength Lead Length 645 nm 0.45" [11.4 mm] 1 3 2 4 Device Length - [9.0] -.355 Pin # 1 2 LED Anode Cathode Pin # 3 4 Transistor Emitter Collector RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
