Vishay Intertechnology Inc. has unveiled the TEKS6400 CMOS photodetector that consumes 455A and operates at a voltage range of 2.5V to 5.5V, making the device suitable for battery-powered devices.

Positioned as an alternative for the company's TEKS5400 device, the TEKS6400 is designed to serve as a steering angle encoder for ESP in automotive systems and as an optical shaft encoder, as well as transmissive or reflective sensor in end products such as printers, copiers and mobile phones.

The 5-by-5-by-2.65mm device is part of the company's Photo Schmitt Trigger product line and features a spherical side-view lens with a 1300 angle of half-sensitivity. The device's high photosensitivity provides high EMI suppression and an integrated daylight filter that is spectrum-matched to IR emitters with a wavelength of 950 nm.

It has a irradiance is 405W/cm2 and produces an output current of 20mA, while dissipating 50mW. The TTL- and CMOS-compatible photo detector features logic outputwith open collector output and a low output signal, if IR light is "on"and a digital interface to the logic IC.

The TEKS6400 is available in an FSZ standard fan-fold packing and is rated for operation at a temperature range of -400C to 850C.
