The GT1 series of Hall effect gear sensors is a digital current sink output (open collector) sensor that can be used to detect ferromagnetic metal targets. It has good signal-to-noise ratio and excellent low-speed performance, the output amplitude is not affected by the speed, the maximum working temperature can reach 150℃, and it has reverse voltage and surge voltage protection. It is suitable for automotive and industrial applications.
The GT1 series Hall‑effect gear sensor detects ferromagnetic targets with a digital current‑sinking output. It operates from 4.5 V to 24 VDC and includes built‑in reverse‑voltage and surge protection, making it suitable for harsh environments.
Typical applications include crankshaft and camshaft speed/position detection in vehicles, as well as chain‑wheel speed monitoring and distance measurement in industrial machinery. The manual also lists target‑size guidelines and installation dimensions. This manual is written in Chinese.
