Piezoelectric Discs

Product catalog summary

Fast Availability of Specified Versions

Application Fields
Piezo components are categorized based on the type of piezo material used:

Ferroelectric Soft Piezo Material (PIC255): Used in sensor technology, actuator engineering, and aerial ultrasound.
Ferroelectric Hard Piezo Material (PIC181): Suitable for high-power ultrasound applications and sonar.

Customized versions are available upon request, with options for dimensions, piezo material, contacting, polarity, electrical connections, assembling technology, and special ambient conditions.

Piezoelectric Discs
These discs are tailored to specific applications with full-surface contact electrodes and can be delivered within two weeks. Larger quantities are available directly from stock.

Specifications

PIC255: Specifications include outer diameter, thickness, resonant frequencies (thickness and radial), electrical capacitance, and coupling factors for radial and thickness oscillation. The resonant frequency can deviate by ±5% (below 2000 kHz) or ±10% (from 2000 kHz).
PIC181: Similar specifications as PIC255, with different resonant frequencies and coupling factors.

Drawings / Images
Includes diagrams for piezoelectric discs, allocation of dimensions, direction of polarization, and displacement due to thickness oscillation.

Ordering Information
Detailed ordering information is provided for both PIC255 and PIC181 piezoelectric discs, specifying the outer diameter, thickness, piezo material, and electrode type for each product code.
