MODEL 7108A ACCELEROMETERSPECIFICATIONSDIMENSIONSIEPE Accelerometer
Wide Bandwidth to 10kHz
10-32 Top Connector
Miniature, Adhesive Mount

The Model 7108A is a miniature adhesive mount IEPEaccelerometer available in ±50g to ±500g dynamic ranges.
The accelerometer features a welded hermetic stainlesssteel construction with a 10-32 top connector. The model
7108A incorporates a stable piezo-ceramic crystal inannular shear mode, installed with a compression ring thateliminates the usage of epoxies that can affect long termstability. The accelerometer has an operating range of 55°C to +125°C and a flat frequency response to 10kHz.
