Fig.1 KM110BH/21 sensor module.
General Philips Semiconductors designed wide range modules meet strong demand contactless angular measurement systems. automotive field alone there many potential applications, such electronic control accelerator pedal, chassis position, steering angle throttle position. Magnetoresistive sensors particular suitable angular position measurement applications, since they operated such way, that their output signal virtually independent Magnet tolerances magnet temperature coefficient Positioning tolerances sensor-magnet distance. Moreover, modules pre-calibrated offset, sensitivity zero point contain integrated temperature compensation. consequence, assembly (encapsulated) sensor easy calibration after assembly becomes superfluous, thus saving considerable costs. More technical details explained next Section "Angular measurement with magnetoresistive sensors".
There module series available. KM110BH/2 family comprises range modules hybrid thick-film technology. circuits magnetic parameters these modules have been chosen that they used: Directly, wide range applications (without further trimming adjustments) basis customized modules. family comprises range encapsulated angular position sensors, which based KM110BH/2 hybrid sensors encapsulation which been developed cooperation with Electronics Werne, Germany. Angular measurement with magnetoresistive sensors With magnetoresistive sensor, different techniques available angle measurement. first, used most magnetic field sensor angle measurement equipment, entails measuring field-strength rotating magnet function angle. With this technique, field used within normal sensitivity range sensor, angles ±90° measured.

However, since magnet's properties influence sensor output, measurement equipment must calibrated after assembly. Only with very well-defined magnetic system would pre-calibrated circuit possible. Defining such system both expensive difficult, tolerances caused thermal sensitivity magnet. second technique, used KM110BH/2 modules, requires strong magnetic fields kA/m). sensor operates `saturation mode', detecting only field-direction. limiting event infinite field strength, field strength drift with temperature have influence sensor. Therefore, using this technique reduces measurementsystem tolerances allows pre-trimming sensors; only requirement that field directions during trimming correspond with field directions after assembly. typical angle measurement range from +45°, sensor output signal sinusoidal. Because this, linear signal obtained central part output characteristic. practice, necessary very strong possibly expensive magnets sensor operate saturation mode. Even with readily available magnets field strengths), influence tolerances temperature drift minimal.

field strengths decrease, peak output signal remains more less constant angle range increases from ±45° maximum ±90° (approximately) very magnetic fields.
