KMXP AMR Linear Position Sensors TE Connectivity's (TE) Measurement Specialties KMXP Anisotropic Magneto-Resistive (AMR) Linear Position Sensors provide high-resolution, high-precision sensing with 10μm to 50μm accuracy in ranges between 1mm and 5mm. TE KMXP AMR Linear Position Sensors with contactless measurement offer greater precision than commonly used Hall sensors. These devices are designed to provide reliable and accurate measurements in high temperatures (up to 150°C) and other harsh environments.
