Active ABS Wheel-Speed Sensors

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

1Use of Hall IC to ensure stable output signals even at low vehicle speed
2Compact, lightweight sensors with few parts
3A type which can sense reverse rotation can also be manufactured
