Profile: Bedford Opto Technology Ltd. is a manufacturer of opto couplers. We are certified with ISO 9001:2000 certification. We specialize in the design, development, and manufacture of opto couplers or opto isolators, and high voltage couplers. OPI5000 is our surface mount certifiable coupler that overcomes the problems associated with coplanearity when converting leaded components to SM. Our OPI 2000 high speed optically coupled isolator consists of a high speed infrared emitter coupled to a silicon photo I.C. The unit is designed for applications requiring high voltage isolation between input & output. We also specialize in designing and manufacturing custom IR products. We avail a standard range of switches and packaged IR components. For the manufacture of precision sensor emitter pairs, we use miniature Pill pack sensors and emitters. These sensors offer high operating temperatures and low optical sqew. The Pill Packs are placed in clean drilled holes in FR4 PCBs, and contact made from each side of the PCB.
