Miniature linear actuators

World's smallest high-speed, high-precision linear actuator

A miniature linear actuator with high precision, high speed and a large travel range?

We can only be talking about Xeryon's XLA.

Powered by our patented ultrasonic piezo motors, these micro linear actuators are extremely versatile and reliable, making them suitable for the most demanding industrial, medical and research applications.

Available with position feedback, without position feedback and hybrid position control.

Linear piezo actuator | XLA

The Xeryon ultrasonic mini linear actuator is a precise and very fast linear piezo actuator driven by our noiseless Crossfixx ultrasonic motor. This allows for high speed motion and precise positioning.

The self-locking piezo motor holds the position of the actuator when it is not powered. As a result, energy consumption and heat generation are considerably reduced.

The XLA is the fastest actuator of such a small size in the world. It is a real OEM product but a break-out board is available for test setups.

Not small enough? We also design custom actuators for your specific product. Contact us to talk about a custom actuator design.

Control types

Open-loop version (without position feedback). Integrated controller, analog/PWM speed and direction control (and limit switches). Ultra-compact. A break-out board is available for testing.
Closed-loop version (with position feedback). External controller (XD-OEM) + integrated position sensor (= go to any position).
Hybrid version: integrated controller + position feedback, but no closed-loop control. Close the loop in your own preferred way.
