You can expect to pay between 0.2 to 245 for each Wheel Encoder. I'm also not sure how well that would work with Hall sensors since they detect a spectrum (analog) signal as opposed to the 1/0 of an optical encoder. The yellow strips are probably adhesives. The magnetic heads are small enough that they can be placed next to each other, with careful spacing, to create a quadrature encoder to increase resolution and gain direction information. Could these be used with servo motors, with the magnetic disc screwed on between the wheels and the servo axle (perhaps with longer screws)?
