TCSS1100/ TCSS2100 is an optical sensor produced by Vishay Semiconductors. It has a compact structure with the light source and detector facing each other on the same optical axis. The operating wavelength is 950nm and the detector consists of a photologic IC with Schmitt trigger and open collector output.
The Vishay TCSS1100 and TCSS2100 are transmissive optical sensors that integrate an infrared emitter and detector on the same optical axis. The device operates at a wavelength of 950 nm and provides a TTL‑compatible output with built‑in voltage regulation.
