High-Sensitivity Piezoelectric Buzzer For Electronic Equipment And Alerts

MEIDI HNR-1407PA75 — a 1407 Piezoelectric Passive Buzzer with Pogo Pin delivering measured 89–94 dB at 4000 Hz. The 14 mm diameter hits a sweet spot between 12.5 mm compact and 22 mm large formats, offering 25% more diaphragm area than 12 mm alternatives without the footprint penalty of 22 mm devices. Operates 1–30 V with 0.63–0.78 mA draw. The 6.7 mm slim profile and 0.85 g mass suit mid-size portable and IoT applications. Black PBT housing rated for 260 °C wave soldering. Request samples or submit RFQ for volume pricing.

MEIDI HNR-1255 PA5.0 is a spring-loaded piezoelectric passive buzzer with pogo pins, measuring 12.5 × 5.5 mm. It operates across 1–30 V and draws only 0.63–0.78 mA. Standing 5.5 mm tall, it cuts 21% off the height of typical 7.0 mm alternatives yet still delivers the same ≥80 dB output at 4000 Hz. Its 12 nF capacitive load pairs well with low-voltage MCU PWM drives. At just 0.60 g, this buzzer targets wearables and space-critical IoT designs. The black PBT housing handles 260 °C wave soldering. Request samples or send an RFQ for volume procurement.

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.
