This magnetic sensor is designed specifically for non-contact encoder applications. Transmitting the angular information tracked off a multi-pole ring magnet, it generates digital, squarewave, offset signals that can be fed into an electronic circuit to determine the direction, angle, and speed of rotation. Because it contains no moving parts, it reportedly is not subject to wear. Replacing the pole wheel with a magnetic ribbon will allow the unit to be used as a measuring system.
