MEIDI HNR-1207 PA6.5 — a 12.5×7.0 mm Piezoelectric Passive Buzzer with Spring-Loaded Pogo Pins with an exceptionally wide 1–30 V operating range and sub-milliampere current draw. Delivers ≥80 dB at 4000 Hz with only 0.45–0.54 mA consumption under 5 Vp-p square wave drive. The 10 nF capacitive load enables direct MCU GPIO drive without external transistors in most 3.3 V and 5 V designs. Weighing 0.66 g, it suits wearable, portable, and battery-critical applications where every milliamp counts. Black PBT housing rated for 260 °C wave soldering. Request samples or submit RFQ for volume pricing.

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.

MEIDI 9*4.2mm Magnetic Passive Buzzer line offers three through-hole electromagnetic units in a shared 9.0 × 5.5 mm form factor, with choices of impedance and frequency. The QMB-09B-03 runs at 16 Ω / 3V / 2.7 kHz for direct 3.3V logic drive. The QMB-09B-05 uses 42 Ω / 5V / 2.7 kHz for 5V industrial bus systems. The QMB-09B-05 4KHZ variant keeps the same 42 Ω / 5V rating but shifts to 4.0 kHz for a sharper, higher-pitched alert. All three fit an identical 9.0 mm PCB footprint with a black PBT housing, so one layout works across multiple voltage designs. Ask for evaluation samples or send an RFQ today. Volume pricing and custom lead forming are available.

MEIDI TMB12A03 Electromagnetic Active Buzzer come in four voltage ratings: 3V (TMB12A03), 5V (TMB12A05), 12V (TMB12A12), and 24V (TMB12A24). All share the same 12.0 × 9.5 mm footprint and black PBT housing. The 5V TMB12A05 measures 96.4–98.7 dB at 2400 Hz across a 3–7 V operating range. By matching the voltage variant to the application, designers get direct compatibility with 3.3V logic, 5V industrial buses, 12V automotive systems, and 24V control circuits — no external regulator required. Send an RFQ for bulk pricing. Engineering samples ship within three days, and OEM customization is welcome.

MEIDI 9mm 5V Electromagnetic Active Buzzer weighs 0.75 g in a through-hole package.Running natively at 12V across an 8–16 V tolerance range, it handles cold-crank voltage dips and alternator spikes without needing a buck regulator. A built-in oscillator produces ≥85 dB at 2700 Hz, and the black PBT housing withstands 255 °C wave soldering. It fits automotive 12V systems, agricultural equipment, and PLC I/O modules well.
