These sensors operate without an external power source and consist of a permanent magnet, a coil of wire and a toothed tone ring (also known as a reluctor ring) attached to the wheel or axle. As the toothed ring spins, it disrupts the magnetic field, generating an alternating current (AC) voltage. The frequency of this voltage corresponds to the speed of the wheel.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Active Wheel Speed Sensors (Hall Effect Sensors)<\/strong><\/h3>\n\n\n\n<p>Active sensors utilise the Hall Effect principle, which requires a power supply to operate. These sensors consist of a Hall element, an amplifier and a signal processor. A magnetised encoder ring with alternating north and south poles is mounted near the sensor.<\/p>\n\n\n\n<p>As the wheel rotates, the sensor reads magnetic changes and produces a digital square wave signal. The signal is constant even at low or zero speed, allowing the system to detect when a wheel stops rotating.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Magneto-Resistive Sensors (MR Sensors or Wiegand Sensors)<\/strong><\/h3>\n\n\n\n<p>Magneto-resistive sensors are a more advanced type of <a href=\"https:\/\/www.dubizzle.com\/blog\/cars\/types-sensors-cars\/\" target=\"_blank\" rel=\"noreferrer noopener\">car sensor<\/a>. They use the magneto-resistive effect, where the electrical resistance of certain materials changes when exposed to a magnetic field. These sensors offer precise readings and can detect both wheel speed and direction of rotation. MR sensors contain an MR element and a signal-processing chip. They work with a specially designed encoder ring that has varying magnetic properties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Comparison Table<\/strong><\/h3>\n\n\n\n<p>Here\u2019s how these wheel speed sensors types compare:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><tbody><tr><td><strong>Features<\/strong><\/td><td><strong>Passive Sensor<\/strong><\/td><td><strong>Active (Hall Effect) Sensor<\/strong><\/td><td><strong>Magneto-Resistive Sensors<\/strong><\/td><\/tr><tr><td>Power Supply<\/td><td>Not required<\/td><td>Required<\/td><td>Required<\/td><\/tr><tr><td>Signal Type<\/td><td>Analog (AC)<\/td><td>Digital<\/td><td>Digital<\/td><\/tr><tr><td>Low-Speed Performance<\/td><td>Weak<\/td><td>Strong<\/td><td>Excellent<\/td><\/tr><tr><td>Direction Detection<\/td><td>No<\/td><td>Sometimes<\/td><td>Yes<\/td><\/tr><tr><td>Weather Resistance<\/td><td>Good<\/td><td>Excellent<\/td><td>Excellent<\/td><\/tr><tr><td>Typical Applications<\/td><td>Older ABS systems<\/td><td>Modern ABS and ESC<\/td><td>Luxury and EV systems<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-importance-of-wheel-speed-sensors\"><strong>Importance of Wheel Speed Sensors<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"640\" src=\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-1024x640.jpg\" alt=\"Mechanical wheel speed sensor types \" class=\"wp-image-16459\" srcset=\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-1024x640.jpg 1024w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-300x188.jpg 300w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-768x480.jpg 768w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-640x400.jpg 640w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-421x263.jpg 421w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-558x349.jpg 558w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-363x227.jpg 363w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-250x156.jpg 250w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-368x230.jpg 368w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-774x484.jpg 774w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-672x420.jpg 672w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-437x273.jpg 437w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-301x188.jpg 301w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-240x150.jpg 240w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-771x482.jpg 771w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-669x418.jpg 669w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17114907\/Types-of-Wheel-Speed-Sensors-C-17-08-435x272.jpg 435w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Active and Passive sensors are two types of wheel speed sensors <\/figcaption><\/figure>\n\n\n\n<p>Wheel speed sensors are a crucial component of modern braking and traction systems, enabling your car to respond quickly and accurately to changing road conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Essential for ABS Function<\/strong><\/h3>\n\n\n\n<p>The ABS relies completely on wheel speed sensors to function. These sensors continuously monitor the speed of each wheel. If the system detects that one wheel is slowing down too fast, signalling a possible lock-up, it reduces brake pressure on that wheel. This helps maintain traction and control during sudden braking, especially on slippery roads. Without reliable speed data from each wheel, the ABS would not be able to react in time, making the vehicle more prone to skidding.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Improves Traction and Stability<\/strong><\/h3>\n\n\n\n<p>Wheel speed sensors also provide critical information to traction control and <a href=\"https:\/\/www.dubizzle.com\/blog\/cars\/electronic-stability-control-system\/\" target=\"_blank\" rel=\"noreferrer noopener\">electronic stability control<\/a> (ESC) systems. These systems use sensor data to identify if a wheel is spinning too quickly, especially during acceleration. If a slip is detected, the system can reduce engine power or apply brake force to specific wheels.&nbsp;<\/p>\n\n\n\n<p>This helps the driver maintain control during cornering, sudden acceleration or when driving on loose surfaces, such as sand. Modern vehicles often combine wheel speed data with inputs from steering and yaw sensors for more precise stability control.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Supports Advanced Driver Assistance Systems (ADAS)<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"640\" src=\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-1024x640.jpg\" alt=\"ABS sensor types in a car\" class=\"wp-image-16466\" srcset=\"https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-1024x640.jpg 1024w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-300x188.jpg 300w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-768x480.jpg 768w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-640x400.jpg 640w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-421x263.jpg 421w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-558x349.jpg 558w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-363x227.jpg 363w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-250x156.jpg 250w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-368x230.jpg 368w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-774x484.jpg 774w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-672x420.jpg 672w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-437x273.jpg 437w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-301x188.jpg 301w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-240x150.jpg 240w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-771x482.jpg 771w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-669x418.jpg 669w, https:\/\/d2hucwwplm5rxi.cloudfront.net\/wp-content\/uploads\/2021\/08\/17115600\/Types-of-Wheel-Speed-Sensors-D-17-08-435x272.jpg 435w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>Keep the sensors clean to protect them from getting damaged <\/figcaption><\/figure>\n\n\n\n<p>In many modern cars, wheel speed sensors play a crucial role in <a href=\"https:\/\/www.dubizzle.com\/blog\/cars\/advanced-driver-assistance-system-adas\/\" target=\"_blank\" rel=\"noreferrer noopener\">advanced driver assistance systems<\/a>. These include <a href=\"https:\/\/www.dubizzle.com\/blog\/cars\/adaptive-cruise-control\/\" target=\"_blank\" rel=\"noreferrer noopener\">adaptive cruise control<\/a>, hill start assist and emergency braking systems. By knowing exactly how each wheel behaves in real time, the vehicle\u2019s computer can make quick and safe decisions without driver input.&nbsp;<\/p>\n\n\n\n<p>For example, in emergency braking, the system can determine the optimal amount of brake force to apply without losing traction. This data also helps the car understand its environment better, improving the performance of lane-keeping and collision avoidance systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Alerts Drivers of Potential Issues<\/strong><\/h3>\n\n\n\n<p>Another important function of wheel speed sensors is fault detection.
