HCL201 Hall gear sensorDetailed product description：

Introduction
HCL201 is a new type of Hall gear sensor used to detect speed, angle, rotational speed, etc. It adopts a unique signal processing method to achieve a working clearance of over 3mm between the sensor and the gear, accurate duty cycle signal output, and a working frequency as low as 0Hz. It is widely used in the speed/position detection of automotive camshafts and crankshafts; Automobile and industrial speedometers; Chain conveyor belt speed and distance detection; Treadmills, etc.

Characteristics
1. Detect black metal.
2. Truly zero speed work.
3. The work gap is large, reaching over 3mm.
4. Accurate duty cycle signal output, wide operating voltage range.
5. Adopting integrated packaging, high reliability.
6. The shell is made of integral copper shell, which is resistant to electromagnetic interference
