Magnetic wheel sensor. Specific model for rally cars. With LED indicator for checking it
Detects the passing of a magnet at a distance of 10mm.
(Millimetres very important in mechanical installations)

2 magnets included in the price. Easy to install.

They permit a reasonable tolerance, which makes them more reliable and means that they can be installed on more cars.

They are long-lasting and very reliable, even under extreme rally behaviour.

They are installed on the non-drive wheels.

Some well-placed sensors won’t make you a winner, but if they are badly installed mechanically a fiasco is guaranteed.

Requires mechanical skills to install it. There are workshops used to work with this kind of equipment.

Each model of car has its own peculiarities. Ask colleagues and mechanics.
