Carrollton, Tex. TT electronics OPTEK Technology has developed a reflective object sensor for detection of diffuse materials. The OPB609 series devices with three different lead options consists of an infrared LED and NPN silicon phototransistor mounted side-by-side on parallel axes. Typical applications 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 940-nm infrared LED offers a maximum forward voltage of 1.7 V and a reverse DC voltage of 5 V. Forward DC current is 50 mA, with a maximum reverse current of 10 uA and peak forward current of 1 A. Power dissipation rating is 75 mW. The operating temperature range for the object sensor is -25°C to +85°C.
The phototransistor features a collector-emitter voltage of 30 V and an emitter-collector voltage of 5 V. Collector DC current is 50 mA, with a power dissipation rating of 75 mW. Custom devices are available including custom electrical specifications, wire and cable and connectors.
Pricing: Ranges from $0.28 to $0.42 each in quantities of 1,000.
Availability: Production quantity lead time, if stock is not available, is eight to ten weeks.
