The AKM390 three-axis Vibration sensor 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 voltage output. AKM390 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...

AKM390 MEMS Voltage-Mode Vibration sensor ► PRODUCT ORDERING INFORMATION ► PRODUCT MEASUREMENT DIRECTION E.g: AKM390-02-T: means ± 2g measure range/standard installation.

AKM390 MEMS Voltage-Mode Vibration sensor ▶ ACCELERATION CALCULATION FORMULA Acceleration = (Output Voltage -2.5V) ÷ Sensitivity The sensitivity can be obtained from the theoretical value of the technical parameters or the actual test E.g: AKF390-02-T (± 2G measurement range, 0 ~ 5V output voltage range) Acceleration = (4-2.5)/1.25 = 1.2g Note: Gravity 1G exists in the vertical direction in the static state. ▶ PRODUCT DIMENSION DRAWING Shell size: L36 × W32 × H24mm Installation size: L29 × W25 × H4mm Mounting screws: 4 M4 screws ▶ DIMENSIONS OF MOUNTING ACCESSORIES Magnetic bottom plate size:...
