The EMC shielding of 19'' IEC 60297 subrack is a systematic engineering process that requires comprehensive consideration of material selection, structural design, aperture and seam treatment, and cable management. With the continuous development of 5G communications, industrial automation, and military equipment technology, the requirements for subrack shielding performance are becoming increasingly stringent.
RDEKONO supplied subrack shielding meets industry-standard EMC standards (IEC 61000-4-3) and the European Union's CE marking (corresponding to EN 55032, EN 55035, etc.), providing adequate protection for internal equipment.
The following are efficient solutions for the shielding structural design of 19'' eurocard subrack:
1. Ensuring Electrical Continuity:
Through the combined action of side panels, crossbeams, and covers, the structural strength and shielding effectiveness of the subrack are enhanced. The synergistic effect of conductive gaskets and V-grooves significantly improves the subrack's shielding performance.
2. Seam Treatment: Gaps are one of the primary causes of degraded shielding effectiveness in shielded subrack. Methods to reduce gap leakage include:
Increasing conductive contact points and reducing gap width
Improving surface flatness using machining techniques
Increasing fastener density
Using electromagnetic sealing gaskets
The following are RDEKONO's accessories of subrack EMC shielding:
Spring steel, tin-plated, ESD clip,for alignment pin in accordance with IEEE
Can be plugged into the guide rails withcoding andinto the keying/coding block
Provides conductive contact between thealignment pin of the insertion/extractor handle (lEL or IET handle) and the horizontal rail
The EMC Gasket (Cover Plate) B easily snaps into the cross member recess of the cover plate, providing a secure conductive connection between the cover and the rail, enhancing the subrack’s overall EMC shielding performance. Its stainless steel construction ensures durability.
The EMC Gasket (Cover Plate) installs directly on the cover plate and fits into the rail groove, maintaining strong electrical continuity and boosting the subrack’s shielding efficiency. Made of high-quality stainless steel for long-lasting performance.
The EMC Gasket (Front Panels) is mounted on the panel or flange side to bridge vertical gaps in the subrack, creating effective conductive contact and improving overall electromagnetic shielding. Constructed from stainless steel and beryllium bronze for superior durability.
Effective EMC shielding of a 19'' Eurocard subrack requires a holistic approach that combines precise structural design, careful material selection, and high-quality conductive accessories. By integrating advanced solutions such as conductive gaskets, ESD clips, and optimized seam treatments, you can achieve exceptional shielding performance that meets stringent industrial and military standards. RDEKONO continues to lead the way in providing reliable, industry-certified EMC subrack systems that safeguard sensitive electronics and ensure long-term operational stability.
1. What is EMC shielding in a subrack?
EMC (Electromagnetic Compatibility) shielding prevents electromagnetic interference from affecting or escaping electronic components housed in a subrack. It ensures stable and safe operation in sensitive environments.
2. Why is EMC shielding important for 19'' Eurocard subracks?
Subracks used in telecommunications, industrial automation, and defense systems often face high electromagnetic interference. Proper shielding protects internal equipment and ensures compliance with international standards such as IEC 61000-4-3 and EN 55032.
3. What materials are commonly used for subrack EMC shielding?
High-conductivity materials such as stainless steel, aluminum alloys, and beryllium bronze are preferred. These materials offer excellent electrical continuity and mechanical strength.
4. How do conductive gaskets improve EMC performance?
Conductive gaskets fill gaps between panels and seams, maintaining electrical continuity and minimizing leakage, which significantly boosts overall shielding effectiveness.
5. What accessories enhance subrack EMC shielding?
Accessories like ESD clips, guide rail discharge clips, and EMC gaskets (for cover plates, front rails, and panels) improve conductive contact and help manage electrostatic discharge within the subrack.

The subrack does not have a series of profiles, and after receiving an order, it is usually customized and processed according to the drawings. Products from different customers and products of different specifications from the same customer all need to be redesigned and processed, resulting in higher costs;
