Wholesale Big Thin wall NdFeB Magnet - Sensor Magnet

China Magnets Source Material Limited provides rare earth magnets (Samarium–Cobalt & Neodymium), hard ferrite and AlNiCo permanent magnet, molded magnets for sensor applications. Custom Permanent Magnets for Sensor Applications Permanent magnets are applied in many electromagnetic transducers, electric machines and measurement instruments. Nowadays the new generation sensors, especially position sensors, are fitted with permanent magnets. In position sensors, they generally use permanent magnet for monitoring rotor position and rotary speed. In reed switches, they generally use permanent magnet for actuation. Sensor Magnet Manufacturer China Magnets Source Material Limited provides rare earth magnets (Samarium–Cobalt & Neodymium), hard ferrite and AlNiCo permanent magnet, molded magnets for sensor applications. They all come in different sizes and shapes. Meanwhile, they have different magnetic strengths. multi-poles ferrite injection molding magnet for sensor Different types of sensors and different working environments require different permanent magnets. Because of magnet’s properties, it should be fully considered shock, vibration, strong external magnetic fields as well as high temperatures in the design of sensor magnet. All these factors will influence the magnetic force and the long term stability in different ways. The sintered neodymium magnet is the strongest magnet. The rare earth smco magnets combine high magnetic force and high working temperature. Alnico magnets are the most stable magnet and can work up to 550°C. Ferrite magnets are the cheapest magnet and their coercivity is higher than alnico magnets. Molded magnets are best for multi-poles requirement and they are customized in variety material, shapes and sizes.
