Product Description
Piezoelectric PVDF Sensors with Round Mass for detect vibration. Made with PolyK 28 um thick piezo PVDF film with high d31.The 0.7 gram mass will increase the sensitivity to detect vibration.
Equivalent to TE LDTM-028K piezo vibration switch sensor with mass.
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.
