SA Series Inertial Actuators

SA series actuators produce vibration in a controlled, precise manner. Their primary uses are in active vibration cancellation, active damping and dynamic testing. These actuators deliver force at a mounting point by reacting against a mass internal to the device housing. The SA family employs a highly-efficient magnetic circuit to deliver high force output per electrical input. Typical bandwidth is 20-1000 Hz and input impedance is 2-20 Ohms. Force outputs range from one to 35 lb (4.5 - 155 N) with much higher output over narrow frequency ranges. CSA offers each of the SA actuators with optional mounting configurations and various electronic drive options. For more information, email actuators@csaengineering.com.
