Inquiry about Ceramic Vibration Sensors

We are seeking ceramic vibration sensors specifically for vibration detection, not pressure or ultrasonic use. High sensitivity to mechanical vibration is required, with a preference for stable and durable ceramic-based solutions. Please provide technical documentation including datasheets, application guides, electrical characteristics (capacitance, output voltage, frequency response), and mechanical drawings. Also, share reliability data such as expected product lifetime and any available test results. Request quotations for quantities of 3,000 pieces and 20,000 pieces, along with MOQ and lead time. Advise on the most cost-effective and precise models available for vibration-only detection.
