MODEL 4630A ACCELEROMETERSPECIFICATIONSDIMENSIONSMEMS Triaxial Accelerometer
Micro-g Resolution, Low Noise
Accurate Temp Compensation
Signal Conditioned Output

The Model 4630A is an ultra low-noise triaxial
accelerometer offering both static and dynamic response.
The silicon MEMS accelerometer is gas damped in orderto provide a wide stable frequency response. The three
independent circuit assemblies have independent signal
conditioning and can operate on common or separate
power supplies. The model 4630A accelerometer isavailable in ranges from ±2 to ±200g with an operatingtemperature range of -55°C to +125°C.
