• Inertial drive and grating closed-loop, suitable for high-precision rotational positioning applications.

Product Features
Piezoelectric inertial drive + closed-loop feedback control

Driven by the inertial principle, it accumulates the deformation of the piezoelectric ceramic to achieve continuous output. A built-in high-precision grating sensor enables high-accuracy closed-loop control.


Flexible filter configuration

Supports flexible configuration with the ability to add or remove filters as needed, accommodating up to five Φ50.8mm standard filters simultaneously.

Power-off self-locking
The piezoelectric filter wheel can achieve self-locking after power-off.
User-friendly control method

Can be controlled via a host computer.

Can also be controlled through commands, supporting homing, absolute motion, relative motion, position query, etc.

Commands can be customized according to user requirements.
