DownloadThe AKM398 three-axis accelerometer is a widely used acceleration sensor series product independently developed and produced, which can be applied in multiple fields such as vibration testing and impact testing. The product adopts analog current output. AKM398 is a single crystal silicon capacitive sensor, consisting of a silicon chip that has undergone micro mechanical processing, a low-power ASIC for signal adjustment, a microprocessor for storing compensation values, and a temperature sensor. This product has low power consumption, has been calibrated, has a sturdy structure, and stable output. The new electronic configuration provides solid-state power for reset and comprehensive protection against over voltage. This series of products features sturdy structure, low power consumption, and excellent deviation stability, ensuring outstanding output reliability.
