SQ-2300 series benchtop motor controller

Developed to simplify computer control of its piezoelectric Squiggle motors and closed-loop linear nanopositioning stages, the SQ-2300 series benchtop motor controller from New Scale Technologies includes an ActiveX command library and USB connection.

The motion control software provides "point and click" Squiggle motor control, and the USB connector provides a plug-and-play interface with a PC. Alternatively, the ActiveX command library from third-party software applications such as LabVIEW can be used. The command library includes both open-loop and closed-loop commands, and an intuitive scripting interface allows users to build their own custom scripts using the ActiveX library, if desired, said the company.

Multiple SQ-2300 controllers can be connected to one PC via a USB hub and driven simultaneously from a single screen, enabling multi-axis "set and hold" positioning. Using the SQ-2300, Squiggle motor speed can vary continuously from micrometers per second to millimeters per second with better than 20nm position resolution, according to the company.

The SQ-2300 can also be controlled by an analog input (0 to 3.3V) or optional manual handset. Key specifications include input power of 12V or 24V at 500mA, and output voltage of 200Vrms. The controller measures 3.5-by-4.2-by-1.6 inches, which is about 30 percent smaller than the previous SQ-2000 series controller, for laboratory and research nanopositioning applications.

The SQ-2300 is priced at $600 including control software, ActiveX command library, and AC wall power adapter.
