TCST1103 Description

Short technical summary and product information.

The Vishay Dale TCST1103 is a transmissive optical sensor designed for applications like optical switches, photo interrupters, counters, and encoders. It integrates an infrared emitter and a phototransistor, positioned face-to-face on optical axes within a leaded package that effectively blocks visible light.

 

Key electrical characteristics include a typical output current of 4 mA for the TCST1103, an emitter wavelength of 950 nm, and a maximum forward current of 60 mA. The sensor operates within an ambient temperature range of -55 to +85 °C and has a maximum total power dissipation of 250 mW at 25 °C.

 

Mechanically, the sensor has dimensions of 11.9 x 6.3 x 10.8 mm with a gap width of 3.1 mm and an aperture width of 1 mm. It is supplied in a leaded package and is compliant with RoHS Directive 2002/95/EC and WEEE 2002/96/EC, with lead-free soldering released.

 

This component is suitable for various industrial and consumer electronics applications requiring precise optical sensing. Its design incorporates a daylight blocking filter for improved performance in ambient light conditions.
