Product Description
Piezoelectric PVDF Sensors (NO Mass) for detect vibration. Made with PolyK 28 um thick piezo PVDF film with high d31.
Equivalent to TE LDT0-028K piezo vibration switch sensor.
Used as Vibration Sensing in Washing Machine.
The crimp pin connectors can be directly plug in and solder in holes on PCB board. The output signal can directly drive MOSFET or CMOS to provide trigger signal in case of vibration.
The resonance frequency can be changed by the mass or free length.
Typical Applications: momentary closure type switches, beam-type vibration sensors for vehicle alarms; solid state switches for counters.

Active film thickness 28 um. sensor size 13 mm x 25 mm, solderable pin pitch 5.08 mm for directly plug into PCB board.
Capacitance 0.455 nF, dielectric loss <1.5%
There is a through hole on the opposite end that you can your own proof mass (as simple as a set of bolt and nuts) to change the resonance frequency and sensitivity to vibration.
with 125 um thick PET backing layer for bending sensor applications.
Other sensor size can be produced upon request.
Wires can be added with additional cost.
We also sell charge amplifiers that will improve the sensor output signal and filter EMI noises [with high pass filter HPF and low pass filter LPF]:
