A speed sensor measures the rotational speed of the wheelset and provides the wheel speed signals required by the braking system. In wheel slide protection systems, these signals are used to detect rapid changes or differences in wheel speed. The braking force can then be adjusted to help prevent the wheels from locking and sliding on the rails.
Noris speed sensors of the FAH52 product family are designed for demanding wheelset applications. Their robust stainless-steel design and various cable protection options provide reliable operation under harsh environmental conditions. Depending on the variant, the sensors offer protection classes IP66, IP68 and IP69.
