Magnetic Position Sensors
Anisotropic Magneto-Resistive (AMR) sensors are precise and contact-less devices that measure the changes in the angle of a magnetic field as seen by the sensor. TE Connectivity's (TE) magnetic position sensors offer robust non-contact position measurements in harsh environments. For example, the unique features of the AMR effect allow the detection of tiny disturbances in the earth's magnetic field created by cars in traffic detection sensors, as well as the measurement of sub-micrometer displacements in precision linear encoders. The AMR sensor technology is also successfully used for presence detection, such as the end-point detection in pneumatic cylinders.
