All the electronic sensors work on a non-contacting basis using magnets this includes Hall and magnetoresistive sensors. The exceptions are the gear-wheel sensors which use a ferrous gear-wheel. The advantage of magnetoresistive sensors is that the same sensor, a standard small model, can be used for different operational distances. The operational distances which can be achieved depend only on the strength of the magnet used. All the models can also be delivered with non-wearing Hall sensors. Besides the various standard models, we also manufacture customised housings to your requirements.
