High-Sensitivity Piezoelectric Buzzer For Electronic Equipment And Alerts

MEIDI 12*5.5mm Piezoelectric Passive Buzzer — 12.5×5.5 mm through-hole piezoelectric passive buzzers with 1–30V ultra-wide drive range and 4000 Hz resonance. PA5.0 and PA6.5 variants share one electrical platform, offering selectable lead lengths for flush or elevated mounting without BOM redesign. ≤10 mA consumption and ≥80 dB output suit battery meters, medical handhelds, and 12V/24V industrial nodes. Request evaluation samples or submit an RFQ for volume pricing.

MEIDI 2310E Active Piezoelectric Active Buzzer — 23×10 mm wire-lead piezoelectric active buzzer with mounting ears, native 12VDC operation and 3–24V survival range. Built-in oscillator generates 3500 Hz fixed tone at ≤4 mA, eliminating external drive circuitry. Sample-verified 91–94 dB output from 23 mm piezo diaphragm suits industrial PLC panels, automotive 12V accessory buses, UPS alarm modules, and solar charge controllers. Black ABS housing withstands wave soldering at 260 ℃. Request evaluation samples or submit an RFQ for volume pricing and custom lead configurations.
