High-Sensitivity Piezoelectric Buzzer For Electronic Equipment And Alerts

The MEIDI HNR-1404 PA7.5 1404 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. It runs on an external AC signal, usually a square wave or PWM near its 4000 Hz resonance, to produce clear audible output. The 1–30 V peak-to-peak drive range works with diverse signal sources, and 5 V serves as the rated test reference. Measuring Φ13.8 × 4.0 mm and weighing 0.67 g, its compact form and black PBT housing support manual soldering for bulk production assembly. Well-suited for procurement across consumer electronics and industrial controls, you can contact MEIDI for technical queries, samples, or volume pricing.

The 1255 Piezoelectric Passive Buzzer with Pogo Pin is a piezoelectric passive buzzer in a through-hole mounting configuration. As a passive device, it requires an external AC drive signal — typically a square wave or PWM at or near the resonant frequency of 4000 ± 500 Hz — to generate audible output.
The 1–30 V operating voltage range is specified for the drive signal peak-to-peak amplitude. The rated voltage is 5 V for test condition reference.
The 12.5 ± 0.3 mm diameter and 5.5 ± 0.5 mm height define the through-hole mechanical envelope. The body mass is 0.60 ± 0.2 g. The black PBT housing material is specified for compatibility with the wave soldering and manual soldering temperature profiles listed in the product specification.

The MEIDI HNR-1707 PA10 1707 Piezoelectric Passive Buzzer with Pogo Pin is a through-hole piezoelectric passive buzzer. It runs on an external AC signal, typically a square wave or PWM around its 4000 Hz resonance, to generate audible output. With a 1–30 V peak-to-peak drive range and 5 V rated test voltage, this buzzer measures Φ17.0 × 7.5 mm and weighs 1.35 g. Its black PBT housing supports both wave and manual soldering for smooth integration into **supplier** production lines. Suitable for **batch orders** across audio alert and industrial systems, contact MEIDI for technical questions, sample evaluation, or volume pricing.

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.
