On the road with the explosive ordnance clearance service

Magnetic multiturn sensors that use the GMR effect (giant magnetoresistance) operate without contact, provide absolute position values, do not require a reference run and do not need a power supply or buffer battery to detect the rotations.

In many mobile and industrial applications, they are therefore a practical alternative to multi-turn potentiometers or optical encoders. The versatile sensors are now also used in robotics, for example in robots for military or police units, which are used for bomb threats, for example.
