OPI1280 Datasheet, PDF (1/2 Pages) OPTEK Technologies – Fiber Optic Isolator-Phototransistor Sensor

Fiber Optic Isolator—Phototransistor Sensor
OPI1280 Series
Features:
• Opaque plastic housings
• High noise immunity
• Visible Red LED with Phototranisitor Output
• 0.05” (1.27 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 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.
Applications:
• Requiring High Voltage isolation between input
and output
• Electrical isolation in dirty environments
• Industrial equipment
• Medical equipment
