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.

Applications: 

Sensing direct contact force, Recording time of an event, Counting number of impact events, Measuring impact-related events, Sensing vibration using cantilevered beam, Wakeup switch, Motion detection
