Fiber Optic IsolatorPhototransistor Sensor
OPI1280 Series
Features:
Opaque plastic housings
High noise immunity
IR LED with Phototransistor Output
0.100” (2.54 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 IR 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.
Applications:
Requiring High Voltage isolation
between input and output
Electrical isolation in dirty
environments
Industrial equipment
Medical equipment

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
