AKM390 Triaxial Accelerometer, Analog Output, Silicon Capacitive Sensor

Product Description:

AKM390 tri-axial accelerometer is a widely used acceleration sensor products independently developed and produced by RION Technology, which can be applied to vibration testing, impact testing and other fields. The product is analog voltage output and can be set with different address codes. Multiple sensors can be connected in series for a long distance, which is convenient for multi-point measurement and data analysis. The AKM390 is a monocrystalline silicon capacitive sensor. It consists of a silicon chip processed by micromachining, a low-power ASIC for signal adjustment, a microprocessor for storing compensation values, and a temperature sensor. This product has low power consumption, solid structure and stable output after calibration. The new electronic configuration provides solid state power for reset and full protection against over-current. The accelerometers have the characteristics of solid structure, low power consumption and excellent deviation stability to ensure the reliability of product output.

Features:

• Three-axis (X, Y, Z)
• Output voltage: 0 ~ 5V
• Power supply voltage: 9~36V
• Operating temperature: -40 ° C ~ + 85 ° C
• Excellent deviation stability, good environmental performance (shock, vibration and temperature)
