Tailored electromagnetic protection component designed for mid-to-high-end precision electronic equipment.
As one of the factory's core mass-produced models, the P-3559-G4 Shield is engineered to deliver high adaptability and robust shielding performance. It has become the preferred protection solution in demanding fields such as industrial control and communication transmission.
This shield adopts high-purity stainless steel as the default base material (with cupronickel material customization available on demand) and is manufactured through a one-piece precision stamping forming process. Its surface is coated with a matte anti-oxidation layer, retaining the excellent conductive and shielding properties of metal materials while enhancing environmental corrosion resistance. It reliably adapts to industrial environments with high humidity and dust, maintaining structural integrity without oxidation or deformation during long-term use.
In terms of structural details, the P-3559-G4 features 7 precisely arranged functional holes. The hole diameter and positions are optimized through electromagnetic simulation to meet the needs of internal heat dissipation, ventilation, and cable routing without compromising shielding effectiveness.
The edges adopt a 1.2mm folding process combined with multi-point positioning buckles on the sides, enabling a tight fit with PCB boards and equipment cavities during installation to minimize electromagnetic leakage gaps. The installation tolerance is tightly controlled within ±0.02mm, ensuring compatibility with the efficient operation of automated assembly lines.
Currently, the P-3559-G4 is widely applied in scenarios such as industrial control PCB boards, communication base station RF units, and core modules of medical in-vitro diagnostic instruments. All production batches comply fully with RoHS environmental standards.
The factory supports comprehensive customization of holes, dimensions, and materials on demand. We provide a free sample prototyping service and offer a mass delivery lead time as short as 7 working days, efficiently meeting the production scheduling needs of customers in the electronics industry.
The shield uses high-purity stainless steel as the default base material, coated with a matte anti-oxidation layer. Cupronickel material customization is also available on demand.
It provides a stable shielding effectiveness of ≥92% within the main operating frequency band of 100MHz-2GHz, effectively blocking external EMI and preventing internal signal leakage.
The shield features 7 functional holes whose diameter and position are optimized via electromagnetic simulation to ensure proper heat dissipation, ventilation, and cable routing without losing shielding power.
The installation tolerance is strictly controlled within ±0.02mm, utilizing a 1.2mm folding process and side multi-point positioning buckles to ensure tight PCB fitting and compatibility with automated lines.
Yes, customization is supported for holes, overall dimensions, and base materials on demand. Free sample prototyping service is also provided.
The lead time for mass production delivery is highly efficient and can be as short as 7 working days.
