Magnetic Hall effect sensors

Low power, highly reliable, cost-optimized solutions for magnetic position sensing

Position measurement

Measure precise absolute position of linear and angular movements within a system to carry out corresponding functions using linear Hall sensors

Proximity detection

Detect the presence or absence of a magnetic field for simple on/off or open/close applications using Hall effect switches

Rotational sensing

Obtain speed and direction for rotary encoding and rotor position for motor commutation using Hall effect latches or linear Hall sensors

Why Hall effect sensors for magnetic position sensing?

Our magnetic Hall effect sensors are known for robust durability and dependable operation for any position sensing application. Whether simply detecting the closing of a lid or performing complex motor commutation and precise position measurement, Hall effect sensors will reliably and accurately sense the position in your system.

Key industrial applications

  • E-meters - Hall effect sensors offer solutions for magnetic tamper and case tamper detection
