Active ABS Wheel-Speed Sensors/ABS Cables

[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.
[ABS Cables]
ABS cables are used as sensor leads of ABS systems, which have now become standard in vehicles to meet the growing demand for safety. The product has very high flexing resistance and mechanical strength to be able to withstand the hostile, complex environment in a running vehicle: flexing by steering, vibration during driving, and possible damage caused by debris. The product is available in several grades of flexibility.
