E1FH781C01 Description

Short technical summary and product information.

The ARDAMP® series dampers from PAULSTRA are engineered with a spring and piston embedded in high-viscosity silicone rubber gel, which is further encased in an elastomer membrane bonded to the case.

 

These dampers offer high performance and significant shock damping capabilities, making them suitable for protecting sensitive electronic equipment, control panels, and measuring instruments. Their applications span across ground vehicles, aircraft, helicopters, and submersible crafts, including civil and military applications.

 

The natural frequency for the ARDAMP® series ranges from 10 to 25 Hz axially and 10 to 20 Hz radially. Damping ratios are specified as 20% c/cc for models E1FH781, 866, and 2507-01, and 17% c/cc for models E1FH76, 77, and 78. The amplification factor at resonance is typically between 2.5 and 3.

 

Available in various sizes and load capacities, these dampers are designed to withstand significant shock inputs, with maximum shock resistance values ranging from 22g to 100g depending on the specific model and shock duration.
