Metal ring

MAGNOPOL offers you magnetic scales to implement in magnetic measurement systems, usually in the form of pole rings (also called encoder wheels, magnet wheels or encoders). The magnetic coding stimulates touch-free field sensing sensor systems with hall or MR sensors. The sensors create a proportional electrical signal in the magnetic field or field direction. In the automotive industry, elastomer-based magnetic pole rings are state-of-the-art. They are used in combustion engines, transmissions or on axles in extreme operating conditions. The magnetic measuring scales from MAGNOPOL have also established themselves in many industrial uses. That is how magnetic pole rings are successfully used in machine tools, robots, lift drives, solar applications, in wind energy and in aerospace. In doing so, MAGNOPOL offers an inexpensive solution, even for smaller quantities – with all competencies necessary for this from a single source: Elastomer technology Magnet technology Measurement technology Technical advising Information worth knowing on magnetic pole rings Pole rings for magnetic measuring systems must safely and constantly represent their function as a measuring scale of measured values over their lifetime and under all operating conditions. There are special requirements stemming from this: High mechanical precision Safe and permanent connection between the magnet and metal stiffening elements Resistance to all operating conditions over its lifetime Homogeneous distribution of the ferrites and highly precise magnetisation for the best signal accuracy
