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. Sensor Magnet Magnets have been used in sensing applications for decades and while the technology has changed little in that time, the huge range of magnet materials and magnetising options have meant that magnetic sensing has kept up with moving technology. Infineon is the global leading semiconductor manufacturer offering all magnetic position sensor technologies with in-house production. Our portfolio comprises Hall sensors, AMR (Anisotropic Magneto Resistive), GMR (Giant Magneto Resistive) or the new TMR (Tunnel Magneto Resistive) sensors. Magnetic Sensors Hall-effect or anisotropic magnetoresistive (AMR) sensor ICs in digital or linear outputs for angle, position & speed sensing; value-added packages. You know us as a leader. In 1968, we revolutionized the industry with the first solid-state keyboard combining Hall-effect sensing and associated electronics in a single circuit.
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 – HSMAG developped magnetic solutions for the sensor / encoder market for many years. The company’s legacy of engineering expertise and customer awareness has created the most reliable and robust magnetic solutions for sensor / encoder technology.
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.
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.
