Composed of Hall elements, a magnet, and signal processing circuitry, it converts magnetic variations caused by rotation of a ferromagnetic detection gear into electrical signals for logic output.
Capable of detection from 0 Hz, with jitter suppression technology enabling precise rotation measurement.
A line driver output type is available for stable operation even with long wiring distances.
Equipped with a reverse-connection protection circuit to prevent failures caused by wiring mistakes.
Accurate detection from start to stop of movement.
Stable detection even in high-temperature environments.
Contact us for models with extended temperature ranges.
- Line driver output
- Semi-open collector output
(open collector + pull-up）
- Differential (balanced) CMOS logic output
Can detect ferromagnetic gears of module m0.5 or larger, and ferromagnetic objects with uneven surfaces (1-2 teeth, holes, etc.).
