Shape Memory Alloy Linear Actuator

Kinitics SMA Linear Actuator delivers high force and precision in a small package

KLA05 Shape Memory Alloy Linear Actuator

Kinitics Automation’s SMA linear actuator is the world’s first industrial-grade linear actuator using shape memory alloy to provide precise linear motion without the use of motors, requiring only AC or DC electrical power to operate. Featuring Kinitics’ proprietary Bundled Wire Technology, this breakthrough product allows users to upgrade and improve existing systems, while also enabling the automation and control of processes that were previously unfeasible using conventional equipment.

The Kinitics shape memory alloy linear actuator delivers high force and high speed in a compact package, making it ideal for applications such as valve actuation, positioning, pressing and gripping. The SMA linear actuator has only one moving part, the rod, and operates without the backlash commong to lead-screw and ball-screw actuators, improving performance in many applications.

Forces up to 2,000 N can be generated and maintained within sub-Newton accuracy while strokes up to 8 mm can be held to within 5 µm. In addition, in a continuous-duty holding application, such as positioning or part-holding, the Kinitics shape memory alloy actuator requires little power, making it an efficient alternative to fluid-power options.
