The KX132-1211 features a max. frequency band of 4,200Hz and acceleration detection range from ±2g to ±16g, while the high-grade KX134-1211 expands the frequency band to 8,500Hz and acceleration range from ±8g to ±64g. In addition, unlike conventional products that can only operate up to 85°C, both models provide operation up to 105°C.
Both accelerometers include customizable frequency filters to remove noise. Frequency filtering and signal power calculation conventionally carried out by a host MCU can now be performed on sensor side, reducing MCU load and associated power consumption.
In addition, the KX134-1211 has a wake-up function that reports when acceleration exceeds a user-defined value. A back-to-sleep function prompts the MCU to switch back to an energy saving mode when acceleration is not detected for a certain amount of time.
