Rotational speed sensor

Features
- High-precision Hall chips
- Fast response
Advantages
- Hall scheme, non-contact, high life, high stability.
- Single Hall: No specific installation direction, high adaptability, suitable for target wheels with fewer teeth/hole counts, typically used for camshafts.
- Dual Hall: Differential signal output, strong adaptability, suitable for target wheels with more teeth/hole counts, commonly used for crankshafts.
- Triple Hall: Differential signal output, generates different pulse widths based on the rotation direction of the target wheel; the ECU determines the rotation direction by analyzing the pulse width, typically applied in transmission gears.
