The TE Connectivity LDT0-028K is a versatile piezoelectric vibration sensor designed for a wide range of applications. It comprises a 28 μm thick piezoelectric PVDF polymer film laminated to a 0.125 mm polyester substrate, equipped with crimped contacts. This flexible component generates high voltages when displaced, acting as a switch or accelerometer depending on the application. Its sensitivity can be adjusted by adding mass or altering the free length, making it suitable for vibration sensing in washing machines, low-power wake-up switches, car alarms, and security systems. The LDTM-028K variant offers enhanced low-frequency sensitivity through a cantilever beam design. Experiment data demonstrates its functionality as a vibration sensor, flexible switch, and frequency response component.
