Piezo elements consist of a piezoelectric ceramic mounted on to a bare metal disc. When an AC voltage is applied across the electrodes of the piezo electric ceramic, it expands and contracts at the frequency applied causing the element to bend, producing sound waves.
Design engineers can use piezo elements within their own housing and enclosure designs. They offer a low cost solution for generating good sound output and also consume minimal power.
Our products range from 12mm to 35mm in diameter and can be supplied with or without leads. The metal discs we offer are predominantly brass however, the ABT-448-90-RC has a stainless steel disc. We offer customised products so if you have a particular requirement please give us a call on 01258 456360 and we will try to assist.
