The KMA199E is a magnetic angle sensor system. The MagnetoResistive (MR) sensor bridges and the mixed signal Integrated Circuit (IC) are integrated into a single package.
This angular measurement system KMA199E is pre-programmed, pre-calibrated and therefore, ready to use.
The KMA199E allows user specific adjustments of angular range, zero angle and clamping voltages. The settings are stored permanently in an Electrically Erasable Programmable Read-Only Memory (EEPROM).
