Request Information Favorite
The Model 4630A is an ultra low-noise triaxial accelerometer offering both static and dynamic response. 

The silicon MEMS accelerometer is gas damped in order to 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 is available in ranges from ±2 to ±500 g with an operating temperature range of -55° to 125° C.
