Honeywell offers the HMC1501 and HMC1512 Magnetic Displacement Sensors. These sensors feature one or two Wheatstone bridge elements to convert magnetic field direction across the silicon die into a voltage output.
The HMC sensors provide better performance than traditional Hall Effect devices for increased accuracy, resolution and field intensity variation. Additional benefits include high sensitivity so that low-cost conventional magnets like AlNiCo and ceramic can be used, as well as insensitivity to shock and vibrations.
Applications include position sensing, rotary speed and angle detection and non-contact precision location measurement systems.
