Compliant. Piezoceramic exempted from requirements of Article 4(1)
Description: When an electric field having the same polarity and orientation as the original polarization field is
placed across the thickness of a single layer disk, the piece expands along the axis of polarization (thickness
direction) and contracts perpendicular to the axis of polarization (radial direction). The motion in the thickness direction is
on the order of tens of nanometers. Motion in the radial direction is typically on the order of microns or tens of microns.
PSI-5A4E is an industry type 5A (Navy Type II) piezoceramic. Thin vacuum sputtered nickel electrodes produce extremely
low current leakage and low magnetic permeability. It operates over a wide temperature range and is relatively temperature
insensitive. The disks are .0075" (.191mm) thick and available in five standard diameters for immediate delivery. We can provide
custom disks to any size. Delivery of custom disks is usually 3 weeks ARO. Contact us for a price quote.

five diameters for immediate delivery. We can provide disks, rings, and non-linear shapes to any size. Delivery of custom shapes
is usually 3 weeks ARO. Please contact our sales department for a quote.
Soldering wires to piezoceramic and/or the center shim can be
difficult without the proper solder and flux. Our kit will get you started with everything you need, plus information on ordering
larger quantities directly from the manufacturer.
