Vishay Launches 940 nm Reflective Optical Sensor with 0.2 to 5 mm Detection Range in SMD Package

Vishay Intertechnology Introduces New 940 nm Reflective Optical Sensor With Detection Range From 0.2 mm to 5 mm in Miniature 3.4 mm by 2.7 mm by 1.5 mm SMD Package MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new reflective optical sensor with transistor output in a miniature SMD package. Measuring just 3.4 mm by 2.7 mm by 1.5 mm, the TCNT2000 offers a detection range from 0.2 mm to 5 mm for consumer, industrial, and computer applications. By utilizing Vishay's high-efficiency 940 nm emitter chip, the TCNT2000 provides a typical CTR of 4 %, outperforming competing devices by a factor of 2. With its high CTR, the device provides designers with the option of increasing the detection range, or driving the device at lower drive currents to reduce power consumption without incurring performance losses. The TCNT2000 features a compact construction with its emitting light source and silicon phototransistor detector arranged in the same plane. The sensor's analog output signal is triggered by detection of reflected infrared light from objects 0.2 mm to 5 mm away (within > 20 % of peak collector current). The TCNT2000 offers a built-in daylight blocking filter, which greatly suppresses disturbing ambient light to increase the signal-to-noise ratio, while keeping the maximum spectral sensitivity at the operating wavelength of 940 nm. The TCNT2000 is designed for optical encoding and switching in industrial metering systems, computer disk drives, and consumer devices such as DVD players. In addition, it serves as an accurate position sensor for shaft encoders and is suitable for office equipment such as copy machines, printers, and fax machines. The TCNT2000 offers a typical output current under test of 0.8 mA. The sensor operates over a temperature range of - 40 °C to + 85 °C and is lead (Pb)-free reflow solderable according to J-STD-020 profile. The device is RoHS-compliant. Samples and production quantities of the TCNT2000 are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery only is $0.32 per piece in 5,000-piece quantities.
