Question on wheel speed sensors

Good quality Quadrature encoders are expensive. Another option is to use a latching hall effect switch and a diametrical magnet. They are very cheap and give 2 transitions per revolution. They are very tolerant of misalignment. They do not give direction.

Expensive is relative. The US Digital E4P is relatively inexpensive, and with appropriate attention to detail it works perfectly.
