This 27mm piezo disc is a versatile transducer used in sound generation and vibration detection applications. It features three contacts: a positive electrode, a negative electrode, and a feedback/ground electrode—making it ideal for both buzzers and acoustic pickups (e.g., CBG guitars).

Applications:

  • Acoustic pickups for musical instruments (CBG, acoustic guitars)

  • Buzzers and sound generators

  • Hartley oscillator circuits

  • Vibration sensors in DIY electronics

Specifications:

  • Resonant Frequency: 4.0 ±0.5 KHz

  • Resonant Resistance: 500Ω

  • Max Capacitance: 20,000pF ±30% @ 1KHz

  • Operating Temp: –20°C to 60°C

  • Storage Temp: –20°C to 70°C

  • Brass Disc Size: 27mm × 0.20mm

  • Ceramic Disc Size: 20mm × 0.25mm

  • Contact Type: 3-lead (positive, negative, feedback/ground)

Note: For acoustic pickup use, cut off the feedback electrode and connect only the electrode and metal plate.
