Introduction to Multipole Sintered Ferrite Magnets for Hall Sensor Applications

12th June 2026

Magnets are indispensable core components of Hall sensor detection systems.
✅ Multipole sintered ferrite magnets advantages:• Low production cost• Stable magnetic performance• Excellent high-temperature resistanceWidely used for motor speed testing, position & angle detection, home appliance control.
📐 Regular shapes: Round / Ring / Hollow CylinderAvailable magnet poles: 4P / 6P / 8P / 12P / 16P & custom poles.When rotating, alternating magnetic fields are sensed by Hall sensors to read speed, position and angle data.
💡 Why choose multipole design for Hall sensing?▪ 2P magnet → 1 signal cycle per full turn▪ 8P magnet → 4 signal cycles per full turn▪ 16P magnet → 8 signal cycles per full turnMore pulses = higher detection precision under same rotating speed.
🛠 Full Customization Available:Shape | Size | Pole quantity | Magnetization | Surface magnetic fluxAll tailor-made to fit your Hall sensor & product design.
🚩 Application Fields:BLDC motor speed detection | Washing machine drives | Automotive cooling fans | Power tools | Smart home appliancesCost-efficient ferrite option for all Hall sensing projects.
