General Description: AMR4100 is based on the principle of anisotropic magnetoresistance (AMR), and its output voltage changes with the direction of the magnetic field (target magnetic field) received. The AMR4100 outputs two sets of analog voltage signals (sine and cosine) with a phase difference of 45° when the magnetic field direction rotates one circle. The period of these two sets of analog voltage signals is twice the rotation period of the magnetic field direction. The angular position information of the target magnetic field can be determined in real time by calculating the two sets of analog voltage signals.

Through the optimized design, the temperature drift of the AMR4100 is effectively compensated, the measurement accuracy of the sensor in various application environments is improved, and the limitation for the installation distance between the measured object and the sensor is reduced. It is available in the compact DFN12L(6 mm × 2 mm × 0.75 mm) packages and easy to assemble in tight spaces.

Features and Benefits: (1)Anisotropic magnetoresistance (AMR) technology;(2)Wide operating voltage range (up to ±9V);(3)Sine/cosine signal output (differential analog signal);(4)Excellent thermal Stability;(5)High accuracy (absolute accuracy 0.1º);(6)RoHS & REACH compliant.

Applications:(1)Linear displacement sensing;(2)Length measurement;(3)Linear encoder;(4)High speed rotation encoder;(5)Angular displacement sensing;(6)Knob sensor.
