OPTEK Technology has developed a family of optical isolators designated the OPI1270, OPI1280 and OPI1290 Series. Consisting of a visible red LED with phototransistor or Photologic sensor, they transfer data through a plastic flexible cable. These isolators were designed for applications that require high voltage isolation between input and output, as well as signal communication over short distances. With high noise immunity and a heavy duty opaque housing to shield the optical signal from dust, they are suitable for industrial, medical and office equipment. Able to mount each end of the isolator at different locations in the system, the design maintains exceptional data transmission characteristics while being available in a variety of custom lengths.
