The GT1 series Hall effect gear sensors have digital sinking output (open collector), better signal-to-noise ratio than electromagnetic induction sensors, excellent low-speed performance, output amplitude is independent of speed. It has a high response speed of -100KHz or more, anti-electromagnetic interference, reverse voltage and surge voltage protection, a wide continuous working temperature range (-40 ~ +150), and can reach 160 ℃ for a short time.
The GT1 series gear sensor uses a Hall‑effect integrated circuit with a biased magnet to detect the motion of ferromagnetic targets. It operates from 4.5 V to 24 VDC and provides a digital current‑sinking output with built‑in reverse‑voltage and surge protection.
Typical applications include crankshaft and camshaft speed/position detection, transmission speed monitoring, tachometers, ABS control in automotive systems, as well as chain‑wheel speed detection, conveyor monitoring, and high‑speed proximity switching in industrial equipment.
