Small but Powerful

The newest addition to National Aperture's family of electronics is the MC-CQ DC-Servo Motion Controller/Amplifier.

This small package contains not only a single-axis motion controller for use with our motorized stages, but also an amplifier and a user-friendly Serial Interface. Each single-axis controller can be linked to multiple Control Units for an integrated multi-axis Motion Control system.

Your purchase will include an easy to use Software Application Development Interface, and an RS-232 serial cable.

The MC-CQ is RoHS and CE compliant.

When combined with National Aperture's "IMS Motion Console Software" users receive a "No-development-required" complete Motion Control system for up to four axes.
