Firgelli Says New Micro Actuator is the World’s Smallest

February 3, 2022

Firgelli Automations has announced developing what it believes is the world’s smallest Diameter Micro Actuator with Positional feedback control, capable of controlling positions to within 1 micron. The technology would revolutionize industries that include robotics, automotive, industrial and medical, the company said.

Robots that require precise movement use electric linear actuators, Firgelli said. The new breakthrough lets users perform things they haven’t been able to until now. The Firgelli Micro Actuator features a small footprint – 16 mm diameter – with a built-in Hall sensor that offers 1-micron positional control capabilities.

Electro-mechanical linear actuators typically do not have built-in positional feedback control for micro actuators because they require too much space, and sensor size has always been an issue. Firgelli said it managed to “crack the code by adopting the world’s smallest Hall Sensor and building it into their new 16mm Diameter Electro Mechanical Linear Actuator.” The actuator is called the Micro Pen Actuator, and aims to provide customers with unparalleled levels of control and flexibility.

Examples of use cases for the micro actuator include robotics that require precise small movements to operate, such as robotic arms, limbs and organs. In the automotive space, micro actuators are required for self-driving cars, as well as tasks such as swiveling a car wing mirror or automatic door opening. In the agriculture space, the height and angle of sprayers can be controlled to provide consistency when used on crops, or when planting seeds.

Firgelli said the actuators are in stock, starting at $135.95. Click here for more details. Additional information about linear actuators can be found here.
