Smartflex Microsprings

SmartFlex Shape Memory Alloy (SMA) microsprings are specifically designed for electrical actuators with strict packaging constraints, providing small forces while delivering 5 times the travel of a standard wire. With a typical outer diameter (OD) range of 0.5 mm to 1.5 mm, forces ranging from 0.25 Newton to 5 Newton, and stroke range of 4 mm to 20 mm, these microsprings offer enhanced performance in compact applications. The unique sensing and actuation capabilities of SMA materials can also be leveraged for thermostatic applications requiring miniature thermal switches.

We excel at custom microspring design and offer preliminary testing, with an average prototyping time of 3 to 6 weeks using production tooling. SmartFlex microsprings are conveniently shipped on continuous spools, and more information can be found in the SmartFlex Brochure.
