ACC 1838
- Micro Triaxial Accelerometer
The ACC 1838 adopts an ultra-miniature built-in integrated circuit, enabling triaxial vibration sensing within an ultra-compact size. It is suitable for a variety of measurement scenarios with strict space constraints.
The ACC 1838 sensor features an integrated design with its cable and cannot be separated. The cable terminates in a 1/4-28 male connector.
