10pcs LDT0-028K Piezo Vibration Sensor Piezoelectric Thin Film Vibration Sensor High Sensitivity AC Coupling

LDT0-028K is a good flexibility of the sensor, the use of 28 mu m piezoelectric film, the screen printing silver paste electrode, the film is laminated on the 0.125mm polyester substrate, the electrode is led by two. When the piezoelectric film is subjected to external force in the vertical direction, it will produce high strain on the film and high voltage output. When the direct effect on the product and the deformation and LDT0 can as a flexible switch, the generated output to directly trigger the MOSFET and the CMOS circuit; if the element by an exit end support and free vibration, the elements like accelerometer and vibration sensors. Adding mass blocks or changing the free length of the element can affect the resonant frequency and sensitivity of the sensor. LDTM-028K using a cantilever beam structure, one end of the signal from the terminal, one end of the fixed mass block, is a high sensitivity of the vibration sensor can be produced at low frequency.
