Programmable Magnetic Angle Sensor

KMA221

The KMA221 is a magnetic angle sensor module. The MagnetoResistive (MR) sensor bridges, the mixed signal Integrated Circuit (IC) and the required capacitors are integrated into a single package.

This angular measurement module KMA221 is pre-programmed, pre-calibrated and therefore, ready to use.

The KMA221 allows user-specific adjustments of angular range, zero angle and clamping voltages. The settings are stored permanently in a non-volatile memory.
