Johnson Electric Launches Shutters for Defense Optronics Industry - Industry's First Piezo Linear and Rotary Shutters

Johnson Electric today announced linear and rotary piezo shutter products optimized for defense applications such as NUC (non-uniformity correction) and filter changers. Launched under the Nanomotion brand, these shutters feature unique direct drive piezo technology with closed loop control, delivering silent operation and low EMI / RFI profiles. Innovative mechanical design creates the closest back-working distance and does not conflict with the footprint of the video assembly. These Nanomotion piezo shutters have the best SWaP (size, weight and power) performance for in-flight, head mounted or hand held devices. The linear and rotary shutters are ASIC closed loop controlled to maintain precision positioning of the shutter.  The control electronics can be supplied as a PCBA or components for system integration.

"These Nanomotion products represent the state-of-the-art in shutter technology", said Jim Dick, Johnson Electric’s senior vice president of Strategic Marketing. "Silent and low EMI devices are essential to prevent detection in the field" he added.
