35mm Piezoelectric Ceramic Brass Disc (XHXDZ-35MM) The 35mm Piezoelectric Ceramic Brass Disc (model XHXDZ-35MM) is a reliable piezo element for sound generation and sensing applications. The unit combines a brass base plate with a bonded piezoelectric ceramic layer to convert electrical energy into mechanical vibrations. When driven by AC or pulsed DC signals, the disc produces clear audible tones or ultrasonic waves, making it suitable for buzzers, alarms, ultrasonic transducers and experimental electronics. Key Features Model: XHXDZ-35MM, 35mm diameter piezo disc Material: Brass base plate bonded with piezoelectric ceramic Efficient sound generation for audible and ultrasonic frequencies Compact and lightweight design for easy integration Durable construction for long-lasting performance Low power consumption; works with AC or pulsed DC drive signals Specifications Model: XHXDZ-35MM Type: Piezoelectric ceramic brass disc Diameter: 35mm Thickness: Approx. 0.5mm – 0.6mm Material: Brass piezoelectric ceramic Typical usage: Buzzer / Sensor / Transducer Applications Piezo buzzers and speakers for alarms and notifications Ultrasonic sensor modules and distance sensing Signal generators, detectors and experimental transducers Arduino, Raspberry Pi and other microcontroller projects Research, prototyping and DIY electronics Installation and Mounting Tips Mount the disc on a flat surface using non-conductive adhesive or silicone for best sound transfer. Avoid clamping the active ceramic surface; secure by the brass backing or housing edges. Keep wiring short and use proper insulation; solder to designed terminal areas or use conductive epoxy where appropriate. Test different mounting arrangements and enclosures to tune audible output and resonance. Electrical Drive and Testing Drive the disc with AC or pulsed DC signals from a signal generator, MCU, or dedicated driver circuit. Use appropriate series resistors or driver transistors when connecting to microcontrollers to limit current and protect GPIO pins. Start with low voltage pulses and gradually increase within safe limits to find the desired sound level and frequency response. DIY Project Ideas Simple piezo buzzer for alarms and timers Ultrasonic distance sensor or object detector (with matching ultrasonic transmitter/receiver circuits) Tone generator for testing audio circuits and enclosures Science experiments demonstrating piezoelectric effect and resonance Why Choose the XHXDZ-35MM? The XHXDZ-35MM delivers a balance of compact size, reliable performance and low power consumption. Its brass-backed construction improves mechanical coupling and durability, while the standard 35mm diameter makes it compatible with many hobbyist and industrial designs.
