App note: AMR angle sensors

Position measurement sensor using magnetoresistive technology discussed in this app note from Analog Devices. Link here (PDF) Anisotropic magnetoresistive (AMR), thin film materials are becoming increasingly important in today‚Äôs position sensing technologies. Magnetoresistive (MR) position measurement has many advantages over traditional technologies. Reliability, accuracy, and overall robustness are the primary factors contributing to the development […]

App note: Magnetoresistive Sensors

Principle of operation of magnetoresistive sensors, app note from Honeywell. Magnetoresistivity is the ability of a material to change resistance under the influence of magnetic fields. There are several different magnetoresistive effects, but Honeywell sensors use the Anisotropic Magneto Resistive (AMR) effect which occurs in ferrous materials, including Permalloy. Permalloy is an alloy of nickel […]
