Position Sensors
Overview
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.
