Due to its featured properties – high sensitivity and almost no hysteresis – the KMY / KMZ sensors are used in a wide range of applications, like magnetic field measurement, revolution counters, proximity detecting, and position measurement. A uniaxial linear magnetic field (in y-direction) will generate a linear output within the specified magnetic field range. The sensor is available in two types: the KMY 20 M, KMY 21 M and KMZ 20 M sensor types contain intrinsic magnets which provide an auxiliary magnetic field (in x-direction) at the sensor die which prevents magnetic domains from flipping irregularly.
Features:
· Output proportional to magnetic field strength with very high sensitivity
· Very small hysteresis and low noise
· Large operating temperature range, from -40°C up to +150 °C
· Highly reliable
· With / without internal magnet
Applications:
· Detection of very weak magnetic fields, like earth magnetic field, or field generated by small magnetic particles
· Detection of objects that distort non-local magnetic fields
· Revolution measurement on ferromagnetic gears
· Contactless switch
· Contactless displacement / position sensor
