Sensing and Control Axial Fiber Optic Isolator OPI270 Series Features: Opaque plas c housings High noise immunity Visible Red LED with Phototransistor Output 0.05” (1.27 mm) lead spacing Data Transfer through plas c fiber op c cable Isola on voltage 15 KV (OPI1270‐032), Longer versions higher Descrip on: Each OPI1270 consists of a visible Red LED and a Phototransistor sensor, which are housed in separate opaque molded plas c housings and coupled by plas c fiber op c cable. The heavy‐duty opaque housing shields the op cal signal from dust, making this series of devices ideal for dust contaminated environments. The OPI1270 series are designed for applica ons that require high voltage isola on between input and output or signal communica on over short distances. Depending on the length of the fiber op c cable, the emi er does not have to be op cally in‐line with the sensor. The isola on voltage is greater than 10 K volts per inch (Isola on distance between components) for all versions of the OPI1270. OPB1270‐032, OPI1270‐040 and OPI1270‐080 conforms to UL 1577 (File # E58730). Custom electrical, wire and cabling and connectors are available.
