Technical content

Each OPR2101 device is a six-element photodiode that is designed to meet the needs of motor encoder applications. Designed specifically for industrial encoder applications, the miniature-sized OPR2101 features a high temperature SMD chip carrier, a temperature range and a low leakage current that can withstand extreme operating conditions. The device has an opaque chip carrier that encloses six individual chips, which are mounted on isolated cathode contacts to allow external connection in any desired configuration. The opaque polyimide package shields the photodiodes from stray light and can withstand multiple exposures to the most demanding soldering conditions, while the gold -plated wraparound solder pads provide exceptional storage and wetting characteristics. See Application Bulletin 237 for handling instructions.  Motor encoder applications  Industrial encoder applications  Six-PIN photodiode array  High-temperature chip carrier  Closely matched responsivity between elements  Easily mountable in any configuration  Suitable for harsh industrial operating conditions
