HMC1501 / 1512 Magnetic Displacement Sensors

The Honeywell HMC1501 and HMC1512 are miniature surface mount sensors for linear, angular, or rotary displacement designed for magnetic saturating feld sensing. The HMC1501 contains a single saturated-mode Wheatstone bridge sense element that
creates an output voltage with respect to the direction of the magnetic flux passing over the sensor surface. The HMC1512 contains dual saturated-mode Wheatstone bridge elements colocated to provide an extended range of angular displacements.
Both sensor types are cost effective and space-effcient solutions for high-volume OEM designs. Applications for the HMC15xx sensors include Position Sensing, Rotary speed and angle detection, and non-contact precision location measurement systems.
The HMC15xx sensors utilize Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over hall-effect based magnetic sensors. They are able to resolve better than tenths of a degree or tenths of millimeters, withstand large variations in magnetto-sensor gaps, and exhibit insensitivity to shocks and vibrations.
