Micro Linear Actuators are used in applications where either space is limited or the stroke requirements are limited. Perhaps you need to move something small or not very far then a Micro Linear Actuator would be ideal for such an application.  

Stroke sizes for a typical Micro Actuator starts at 10mm and then increases there by approximately 10mm increments up to about 100mm (4") after this stroke the Actuator probably can no longer be classified as a Micro Actuator and instead becomes simple a small compact actuator like the FIRGELLI Classic style Actuator. 

Micro linear actuators are quite versatile with respect to the range of applications they are suited towards. Since most come with built in feedback they are also suited towards applications requiring precision control and force capabilities which, while impressive compared to their size, is perfect for those who require it on a small scale.

Popular applications of micro linear actuators include the consumer electronics and automotive industry as well as Robotics, where these actuators can be seamlessly integrated into their interior and exterior systems.
