TE's magnetic sensors are precise and contact-less devices that measure the changes in the angle of a magnetic field as seen by the sensor.
Anisotropic Magneto-Resistive (AMR) Sensor Components. TE Connectivity's magnetic sensor components 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 magnetic field created by cars in traffic detection sensors, as well as the measurement of sub micrometer displacements in precision linear encoders. The AMR technology is also successfully used for presence detection, such as the end point detection in pneumatic cylinders. TE's AMR sensor components are widely used in a variety of automotive, industrial, medical and consumer applications. In general, AMR sensors convert the magnetic field direction into an electrical signal. All AMR sensor components are packaged in attractive modern packages and are ROHS and REACH compliant.
Due to its featured properties - very high sensitivity and almost no hysteresis, combined with low noise – the KMY / KMZ sensors are used in a wide range of challenging applications, like magnetic field measurement, revolution counters, proximity & presence detection, and position measurements
