MODEL 7104A ACCELEROMETERSPECIFICATIONSDIMENSIONSIEPE Accelerometer
Wide Bandwidth to >10kHz
10-32 Side Connector
Stud Mount, Hermetic

The Model 7104A is a high performance IEPE
accelerometer available in ±50g to ±1000g dynamic ranges.
The stud mounted accelerometer features a welded
hermetic construction with a side mount connector. Themodel 7104A incorporates stable piezo-ceramic crystals inannular shear mode which provide a flat frequency
response up to >10kHz. The standard operating
temperature range extends from -55°C to +125°C.
