The Vishay VCNT2020 is a compact reflective optical sensor designed for applications requiring object detection and position sensing. It features a phototransistor detector and operates with an infrared wavelength of 940 nm. The sensor is integrated into a miniature SMD package, measuring 2.5 x 2 x 0.8 mm, making it suitable for space-constrained designs.
Key electrical characteristics include a maximum forward current of 100 mA and a collector-emitter breakdown voltage of 20 V. The sensor has an operating range of 0.2 mm to 2.5 mm for detecting reflected infrared light. It also includes a built-in daylight blocking filter to improve signal-to-noise ratio.
Applications for the VCNT2020 include position sensing, optical switches, optical encoders for disc and tape drives, and object detection in devices like printers and copy machines. The sensor is mounted via surface mount technology.
