1. Product profile
1.1 General description
The KMA220 is a dual channel magnetic angle sensor module. The MagnetoResistive
(MR) sensor bridges, the mixed signal Integrated Circuits (ICs) and the required
capacitors are integrated into a single package. Both integrated channels are working full
independently. The supply voltage has common terminals. Further explanations are
referring to a single channel of the KMA220.
This angular measurement module KMA220 is pre-programmed, pre-calibrated and
therefore, ready to use.
The KMA220 allows user-specific adjustments of angular range, zero angle and clamping
voltages for each channel separately. The settings are stored permanently in a
non-volatile memory.
