Sonic Actuator brochure

There are some common specifications among each of ETREMA's Terfenol-D based Sonic Actuators. One such characteristic is the standard operating frequency range, which is 0-1250 Hz. A high frequency version, which covers the range 0-2500 Hz is available for models 050, 100, and 150. The remaining common specifications are:

Feature Specification Dynamic Force, lb (N) 250 (1110) Blocked Force, lb (N) 500 (2220) Operating Temperature Range, °F (°C) -4 to 212 (-20 to 100) Max. Continuous AC Current, Arms 5

Unique specifications to each model are as follows:

Model Max. Stroke (DC), µm Resistance (DC), Ω Inductance, mH Weight lb kg AA-100L ± 50 1.9 3.6 8.4 3.8 AA-150L ± 75 2.8 5.5 10.6 4.8

Actuator Options:

Each ETREMA actuator has options to help suit our customers' needs. Below is an example of a typical actuator order configuration, with the available options shown.

The electrical interface is customer-specified to be located either at the bottom of the device (in the axial direction of the actuator), or at the side. Electrical connection is accomplished via a supplied cable with a locking, splash-proof LEMO connector.

The actuator can also be ordered either as a sealed or air-cooled version. The location of the 1/8-27 NPT air connection is the same as the chosen location for the electrical connection.
