The Honeywell HMC1501 and HMC1512 are miniature surface mount sensors for linear, angular, or rotary displacement designed for magnetic saturating field 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-efficient 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 magnet to-sensor gaps, and exhibit insensitivity to shocks and vibrations. Honeywell's Magnetic Sensors are among the most precise and reliable position sensors in the industry. Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic sensor solutions. These are highly reliable, top-performance products that are delivered when promised. Honeywell's magnetic sensor provide real solutions you can count on.

Magnetic Mounting Considerations
The HMC1501 has an internal sensor die placed toward the forward edge, between pins 1 and 8, to make linear translation applications more convenient. The figure below indicates this location.
The HMC1512 has two sensor bridges optimized for rotary translation applications. Thus the die is centered in all three dimensions within the SOIC-8 package. The figure below indicates location.
Basic Device Operation
The Honeywell HMC15xx magnetoresistive sensors are Wheatstone bridges to measure magnetic field direction. The bridge elements change their resistance when a magnetic field is applied across the silicon die with the thin films of magneto-resistive ferrous material forming the resistive elements. The magnetoresistance is a function of cos2θ , where θ is the angle
between the applied magnetic field (M) and the current flow direction in the thin film.
When the applied magnetic field becomes moderate (50 Oerstad or larger), the magnetization of the thin films align in the same direction as the applied field; and becomes the saturation mode. In
this mode, is the angle between the direction of the applied field and the bridge current flow, and the magnetoresistive sensor is only sensitive to the direction of the applied field (not amplitude).
The sensor is in the form of a Wheatstone bridge (see figures below). The resistance (R) of all four bridge legs is the same. The bridge power supply Vb or Vbridge, causes current to flow through the bridge elements as indicated in the figures.
Both the HMC1501 and HMC1512 are designed to be used in saturation mode, with applied fields of 80 Oerstads or greater, required to meet the specifications in this datasheet.
