00 — Overview

What the TCUT1350 does

The TCUT1350X01 is a subminiature dual-channel transmissive optical sensor featuring an infrared emitter and two phototransistor detectors in a surface mount package. It operates with a 3 mm gap, 0.3 mm aperture, and 950 nm emitter wavelength, delivering 1.6 mA typical output current. The device supports a 3-30 V single supply, handles 25 mA forward current, and functions across -40 °C to +125 °C. AEC-Q101 qualified for automotive use, it serves as an accurate position sensor for encoders or a detector for motion, speed, and direction in industrial applications.
