Electric Linear Actuator

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

KLA05 Electric Linear Actuator

Kinitics Automation’s high-force, short-stroke electric linear actuators use shape memory alloy to provide fast-acting, precise linear motion in a compact package. The actuators require only 120 VAC or 12-24 VDC electrical power to operate and do not use motors. With only one moving part – the rod – backlash common to lead-screw and ball-screw actuators is eliminated. This breakthrough product allows you to upgrade and improve an existing system, or automate a process that was previously unfeasible using conventional equipment.

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 ┬Ám. In addition, in a continuous-duty holding application, such as positioning, the Kinitics electric linear actuator requires little power, making it an efficient alternative to fluid-power options.
