Dual-Channel Programmable Angle Sensor

KMA220

Roll over image to zoom in

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 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.
