Piezo Element (Diaphragm)

DESCRIPTION

The 7BB series from Murata is piezoelectric diaphragms. These piezoelectric diaphragms are piezoelectric ceramic disks adhered to metal plates of brass. These diaphragms are typically used in clocks, calculators, digital cameras and various alarms. They can be used as knock sensors or very small audio transducers.

This piezo element is 20mm in diameter and has a height of 0.2mm.
