This is the 2020 XLA micro linear actuator, driven by ultrasonic piezo. Is comes in an open-loop and a closed-loop version. The closed-loop version is available with 1250 nm, 312 nm and 78 nm position encoders and is the smallest in the world. Speeds of 500 mm/s are possible in closed-loop and in open-loop speeds of more than 1000 mm/s are realistic.
