The Honeywell HMC1501 is a miniature surface mount sensor for linear, 90° 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. It's a cost effective and space-efficient solution for high volume OEM designs. Applications for the HMC1501 sensor include Position Sensing, Rotary speed and angle detection, and non-contact precision location measurement systems. The HMC1501 sensor utilize Honeywell’s Anisotropic Magneto-Resistive (AMR) technology that provides advantages over hall-effectbased magnetic sensors. It is 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.
