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.
