The MK920 three-axis accelerometer is a widely used series of acceleration sensors produced by Msensor Sensor Technology Co., Ltd. using introduced core technology. It is suitable for various fields such as vibration testing and impact testing. Output interfaces: 0~5V, 0.5-4.5V, 0-10V are optional. The MK920 is a monocrystalline silicon capacitive sensor, composed of a silicon chip processed by micromechanics, a low-power ASIC for signal adjustment, a microprocessor for storing compensation values, and a temperature sensor.
The product is small in size, low in power consumption, calibrated, structurally fixed, and has stable output. The new electronic configuration provides solid-state power for reset and comprehensive protection against overvoltage. The long-term stability of the proportional factor and the typical deviation across the full range is less than 0.1%. This series of products features fixed structure, low power consumption, and excellent deviation stability, ensuring reliable output stability.
