Fiber Optic Isolator—Photologic

OPI1290 Series

Applications:

and output

Features:

RoHS

Description:

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.

Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more

information.
