TE Connectivity LDT0-028K Piezo Vibration Sensor No-Mass - Solder Tab Connection
The TE Connectivity LDT0-028K is a flexible piezoelectric vibration sensor based on a PVDF polymer film, generating a high-voltage output signal directly from mechanical bending or impact. It is designed for direct interfacing with MOSFET or CMOS logic stages, suitable for impact detection, vibration monitoring, and flexible switching applications in industrial and electronic systems.
Features
- Flexible PVDF Piezoelectric Film Sensor with 28 µm active layer
- Generates high-voltage output sufficient to directly trigger MOSFET/CMOS gates
- Dual-mode operation: acts as a flexible impact switch or inertial vibration sensor
- Robust solder tab connections for reliable electrical integration
- Wide operating temperature range from 0°C to 85°C

The LDT0-028K sensor utilizes a 28 µm thick piezoelectric PVDF polymer film laminated to a 0.125 mm polyester substrate, with screen-printed silver ink electrodes. Bending the film displaces it from the mechanical neutral axis, creating high strain within the piezopolymer and generating a correspondingly high output voltage. This principle allows the device to function either as a direct-contact flexible switch or, when mounted as a cantilever, as an accelerometer responding to inertial vibrations.
The sensor’s sensitivity and resonant frequency can be tuned by adding mass or altering the clamped free length of the element, enabling customization for specific application requirements. Its construction is designed to withstand high-impact events while providing a reliable, solderable interface for integration into control circuits, condition monitoring systems, and impact detection assemblies.
