Description:
Each
OPI1290
consists of a visible Red 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.
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

Notes:
(1) Derate linearly 2.5 mW/° C above 25° C for all devices in the OPL550, OPL551, OPL560, OPL561, OPL562 and OPL563 series.
(2) Irradiance measurements are made with
λi
= 935 nm.
(3) Storage and Operating temperature values are based on the plastic optical interface temperature ratings. Please reference
