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.

Notes:
1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum 20 grams force
may be applied to the leads when soldering.
2. Derate linearly 1.33 mW/° C above 25° C.
3. Isolation voltage testing is required.
4. Storage and Operating temperature values are based on the plastic optical interface temperature ratings. Please reference UL1577
and UL file AVLVZ.E89328
