TCUT1200 is a miniature transmissive optical sensor with phototransistor outputs, released for lead (Pb)-free solder process.
The TCUT1200 is a sub‑miniature dual‑channel transmissive optical sensor packaged for surface‑mount use. It features an infrared emitter (950 nm) and two phototransistor detectors positioned face‑to‑face, with a 2 mm gap and 0.3 mm aperture. Typical output current is 0.5 mA and the device meets RoHS lead‑free requirements.
Electrical characteristics include a collector‑emitter voltage rating of 70 V, forward current of 25 mA, and power dissipation of 75 mW. The sensor operates from –40 °C to +85 °C ambient temperature and is suitable for applications such as accurate position sensing, motion‑direction detection, and computer mouse/trackball interfaces.
