描述 Description

The KMA220 is a high precision dual channel magnetic angle sensor for magnetic angular measurement. The MagnetoResistive(MR) sensor bridges, the mixed signal Integrated Circuits (ICs) and the requiredcapacitors are integrated into a single package. Both integrated channels are working fullindependently. The supply voltage has common terminals. Further explanations arereferring to a single channel of the KMA220.
This angular measurement module KMA220 is pre-programmed, pre-calibrated andtherefore, ready to use.
The KMA220 allows user-specific adjustments of angular range, zero angle and clampingvoltages for each channel separately. The settings are stored permanently in anon-volatile memory.
