20mm Piezo Electric Transducer Element
Original price was: ₹51.00.₹46.00Current price is: ₹46.00. (Inclusive of GST)
- Disc / plate diameter: 20 mm
- Element diameter (piezo ceramic inside): 14 mm
- Plate thickness: ~0.42 mm
- Pre-wired leads: yes (approx. 50 mm lead length)
- Resonant / operating frequency: ≈ 6.3 kHz ± 0.6 kHz
- Operating voltage: typically, 3 V to 12 V DC (per some seller spec)
- Sound output (as buzzer / driven): likely ~85–90 dB @ 10 cm (depending on drive and environment)
- Disc material: Brass (resonant plate) + piezo‐ceramic element
- Passive transducer: requires external drive signal (no built‑in oscillator) — good for use as speaker, pickup or buzzer depending on drive.
- Compact, lightweight — suitable for small electronics, instruments, alarms, DIY projects
Description
This is a simple, small 20 mm piezo‑electric transducer sold in a pack of three. Each unit consists of a thin brass resonant disk with a piezo‑ceramic element and pre-wired leads, designed to convert electrical signals into sound (or vice versa if used as a sensor). Because it’s passive and requires an external signal (oscillating voltage) to produce sound, it’s versatile — usable as a buzzer, contact microphone/pickup, alarm alerter, or for DIY electronics and instrument projects.
PACKAGE INCLUDES:
- 3 × Piezo buzzer / transducer discs, each pre-wired with lead wires.
