SWT’s Second‑Smallest Piezo Micro‑hole Atomizer Optimized for Perfume Diffuser Devices

Miniature aroma diffusers and compact fragrance appliances require specialized piezo atomizer components compatible with perfume‑based working media. The piezo micro‑hole atomizer converts high‑frequency electrical signals into rapid mechanical vibration, turning perfume or water into fine, uniform cool mist. Gd SWT Smart Tech Co., Ltd. (www.swt99.com), operating under the SWT brand, develops and manufactures this second‑smallest piezo micro‑hole atomizer. Drawing on abundant piezo‑ceramic R&D and mass‑production experience, SWT delivers reliable atomizer parts tailored for compact fragrance‑spraying end‑products.

Understanding SWT’s Second‑Smallest Piezo Micro‑hole Atomizer and Its Application Value

SWT’s micro‑hole piezo atomizer lineup covers multiple size grades. This model is SWT’s second‑smallest piezo micro‑hole atomizer, purpose‑built for perfume diffusers and small scent devices. Adopting precision laser micro‑drilling technology, it can stably atomize perfume liquid without heating. It avoids thermal damage to fragrance ingredients, making it highly suitable for desktop aroma diffusers, portable scent dispensers and mini fragrance machines.

This atomizer unit comes pre‑fitted with red‑black lead wires and a P1.25‑2P white connector for straightforward assembly. Engineers can match it with dedicated driving circuits to acquire stable mist output. Rigorous production process control guarantees consistent electrical performance and service life, supporting large‑scale OEM manufacturing for aroma appliance manufacturers.

Technical Specifications and Product Line Highlights

The representative model is ATC12.8‑0135SDWB, SWT’s second‑smallest piezo micro‑hole atomizer.

Key electrical parameters: static capacitance 2000±25% PF (tested at 25 ℃, 1 KHz); resonant frequency 135±10 KHz (measured by HP‑4194 Impedance Analyzer); resonant impedance ≤400 Ω. Rated service life ≥1000 hours. It supports perfume as working liquid, with water‑rate fog output ranging from 2‑4 mg/s.

Mechanical dimension: outer diameter φ12.8±0.5 mm. Laser‑drilled structure: aperture 5‑6 μm, total hole count 30, punching area 3.0 mm. It is equipped with 20‑0.080D0.8 red‑black wires and P1.25‑2P white terminal connector. Its compact size fits tightly inside tiny aroma housings, allowing product developers to create mini fragrance devices while maintaining stable atomizing performance for perfume liquids.
