Piezofilm LDT1-028K Series

Image LDT1-028K

The LDT1-028K is a multi-purpose, piezoelectric sensor for detecting physical phenomena such as vibration or impact.

The piezo film element is laminate to a sheet of polyester (Mylar), and produces a useable electrical signal output when forces are applied to the sensing area.

The dual wire lead attached to the sensor allows a circuit or monitoring device to process the signal.
