Active ABS
Wheel-Speed Sensors
Overview
These are wheel-speed sensors with semiconductor sensing elements to respond to the advances in ABS. The sensors provide stable output throughout, from low to high speed. Another product type that can sense reverse rotation is also available upon request.
Features
- １．Use of Hall IC to ensure stable output signals even at low vehicle speed
- ２．Compact, lightweight sensors with few parts
- ３．A type which can sense reverse rotation can also be manufactured
