Description:

Each OPI1290 consists of a IR 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 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 OPI1290.

Features:

• Opaque plastic housings

• High noise immunity

• IR LED with Phototransistor Output

• 0.05” (1.27 mm) lead spacing

• Data Transfer through plastic fiber optic cable

• Isolation voltage 15 KV (OPI1290-032), Longer versions higher

Applications:

• Requiring High Voltage isolation between input and output

• Electrical isolation in dirty environments

• Industrial equipment

• Medical equipment

• Office equipment
