Piezo benders with low operating voltage
The new PI Ceramic range of piezo multilayer bender elements can produce deflections of up to +/- 1.0 mm with sub-micron resolution.
The new PI Ceramic range of piezo multilayer bender elements can produce deflections of up to +/- 1.0 mm with sub-micron resolution The multilayer bender elements can withstand a force of up to 1.1 N, have a response time in the millisecond range, and require an operating supply of only 60 Volts (or +/- 30V)

Infrared Imaging : The best gets better
Viewing infrared wavelengths between 0.4-1.5microns, the converted image produced by the new 7215 is now brighter and offers edge to edge sharpness.
Maximum operating temperature is up to 125 deg C.
Applications where multilayer piezo benders have been employed include wire bonding, optical and electrical switching, medical instrumentation, micropositioning, light beam deflection and acceleration sensing.
Four standard, off the shelf elements are available ranging in size from 25 mm long x 9.6 mm wide x 0.65 mm thick to 45 mm long x 11 mm wide x 0.6 mm thick.
The actuators are manufactured from 40 micron ceramic layers using a co-firing process.
The classic design of piezo bimorph, by comparison, normally consists of two ceramic layers, between 0.1 and 1mm thick, which are glued together.
The multilayer production method imparts to the bender elements a faster response time, a higher stiffness, and a lower operating voltage when compared to a bimorph design. Request a free brochure from Lambda Photometrics ...
