Precision Linear Actuator

Kinitics Bundled Wire technology delivers high force and accuracy in a small package


High force, high speed, high precision: Kinitics’ shape memory alloy technology generates up to 2,000 N force and up to 8 mm stroke with incredible accuracy.

No motors: The KLA precision actuator has only one moving part – the rod – for a compact size and no backlash, yet requires only 120 VAC or 12-24 VDC power to operate.

Precise: Forces can be maintained within sub-Newton accuracy while strokes can be held to within 5 µm (.2 mil).


KLA05 Precision Linear Actuator

Kinitics Automation’s KLA precision 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. 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 precision 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. 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.
