The GEL 2471, 1- or 2- channel speed sensor is used with electrically conductive measuring scales with an up to 4 mm air gap.
It is a maintenance and wear-free operation due to non-contact measurement of rotation with, Strong reinforced walls in the sensor tube with a diameter of 20 mm provide increased protection against the impact of stones, grit and foreign objects.
If you are trying to build to a weight limit, the gel 2471 is perfect due to its construction with light-weight target wheels made of aluminium.
