OPTEK Develops Reflective Object Sensor For Detection Of Diffuse Material

Carrollton, TX TT electronics OPTEK Technology, a leading manufacturer and supplier of optoelectronic components, has developed a cost-effective reflective object sensor with three different lead options. Designated the OPB609 Series, the sensor consists of an infrared LED and NPN silicon phototransistor mounted side-by-side on parallel axes.
According to Alan Bennett, vice president of sales and marketing for OPTEK Technology, the OPB609 Series object sensors were developed specifically for the detection of diffuse materials. "The device is housed in a black opaque package, features a high speed phototransistor output and is unfocused, allowing it to properly sense diffuse surfaces," said Bennett. "By using a plastic housing, we are able to provide our customers with a cost-effective device ideally suited for the detection of paper, labels or any material with a matte finish."
Typical applications for the reflective object sensor include assembly line and machine automation, machine safety, end-of-travel sensing and door sensing, as well as edge, paper jam and mark detection.
The OPB609 Series reflective sensor is available with axial, gull wing or right angle lead configurations. The epoxy package spectrally matched to IR emitter l = 940nm, cutting wavelength under l = 840nm. The phototransistor features a collector-emitter voltage of 30V and emitter-collector voltage of 5V. Collector DC current is 50mA, with a power dissipation rating of 75mW.
The 940nm infrared LED has a maximum forward voltage of 1.7V and a reverse DC voltage of 5V. Forward DC current is 50mA, with a maximum reverse current of 10µA and peak forward current of 1A. Power dissipation rating is 75mW. Operating temperature range for the object sensor is -25°C to +85°C.
OPTEK will also produce devices to meet specific customer requirements. Custom electrical specifications, wire and cabling, and connectors are also available.
