Anti-lock braking system or ABS for short, is a safety system used on aircraft and on vehicles, such as cars, motorcycles, trucks and buses. When a sudden brake is applied, particularly when the vehicle is already turning, the ABS operates by preventing the wheels from locking up during braking. The on-board electronics need to apply differential hydraulic pressure to each brake to prevent the car from fishtailing and skidding. This is achieved by measuring the speed of all the wheels individually by using reed sensors that mounted near the wheels and magnets on the wheels themselves. This way, the individual rotational speed of each wheel is fed back to the computer, as braking takes place, and if certain wheels are spinning faster or slower, more or less hydraulic oil pressure is fed into those corresponding brake discs. This almost ensures smooth braking of the vehicles, under trying situations. Suitable products: MS-228 threaded sensors, and MS-216-L cylindrical sensors.
