OPTEK Technology has developed a wide gap optical sensor that includes an emitter-sensor pair. Designated the OPB856Z Series, the product consists of an LED and a phototransistor designed to operate efficiently over distances up to 12 in industrial environments. Additional applications for the wide gap optical sensor include non-contact interruptive object sensing, equipment security and machine safety. The wide gap optical sensor components are mounted in threaded color-coded housings; the LED (white housing) and phototransistor (black housing) are designed for easy panel mount through a 12 mm (0.473?) hole, with a corresponding nut included for each housing. The emitter uses an LED with a 935 nm peak wavelength, matched to a silicon phototransistor (sensor). Electrical performance of the output phototransistor is characterized at collector-emitter voltages of 30V, emitter-collector voltage of 5V, and power dissipation of 100 mW. OPTEK will also produce devices outside these specifications to meet customer requirements. The OPB856Z Series sensors are RoHS-compliant, as well as compatible with reflow and wavesolder temperature of 260C seen by the device. Rated operating temperature is -40C to +85C.OPTEK Technology 972-323-2200 www.OPTEKinc.com Click on this URL for more: www.rbi-infolink.com/infolinksearch/aspx/resultsframe.aspx?pub=EC&isn=6E37072&lead_source=DIGITAL
