When it comes to designing reliable electronics systems, using your module rack correctly is critical. A well-designed rack secures PCBs, provides electromagnetic shielding, enables modular maintenance, and supports optimal cooling. This guide explains exactly how to configure module racks—covering standards, component selection, and best practices—while also recommending high-quality Rdekono solutions.
A module rack (also known as a subrack) is a structural enclosure built to house PCB boards in plug-in units. It must comply with standards like IEC 60297 Subrack and GB19520. Module racks provide:
1. Physical Protection : The module case provides a robust enclosure for PCB boards, shielding them from physical damage such as impacts, scratches, or dust.
2. Electromagnetic Compatibility (EMC) Protection: Designed with electromagnetic shielding, the module rack reduces electromagnetic interference (EMI) and electromagnetic susceptibility (EMS), ensuring stable operation of the PCB and its components in complex electromagnetic environments.
3. Organization and Management : With standardized dimensions and interfaces, the module rack enables easy installation, removal, and replacement of PCB boards, facilitating system maintenance and upgrades.
4. Heat Dissipation and Ventilation: Some module racks incorporate heat dissipation features such as ventilation holes or fans to ensure timely heat dissipation during operation, preventing performance degradation or damage caused by overheating.
5. Standardization and Compatibility: By adhering to international standards, module racks allow interchangeable use of PCB boards from different manufacturers, enhancing system compatibility and flexibility.
A correctly configured module rack ensures:
Secure mechanical support and grounding
Reliable shielding performance in harsh electromagnetic environments
Efficient cooling for stable operation
Easy system upgrades and maintenance
Faster development cycles when using standard parts
Correctly matching rack components—especially in high-performance scenarios—can significantly lower costs and risks.
In summary, module racks play a vital role in the assembly, maintenance, and upgrading of electronic equipment. They not only protect PCB boards from damage but also improve system reliability and performance.
A standard module rack consists of numerous components. Even customers familiar with similar cases may not have encountered such a wide array of parts, as many users only engage in simple applications, ultimately encapsulating the PCB within the case.
Leveraging a comprehensive library of module rack components can significantly reduce design and validation time, lowering project costs and timelines.
1. Select the Correct Form Factor (3U / 6U / Widths)
Standard heights: 3U (132.6 mm) or 6U (266.7 mm)
Width measured in HP/TE units (1 HP = 5.08 mm), with a min width of 5 HP
Choose the form factor based on PCB size, I/O layout, and slot quantity
2. Choose a Compatible Subrack Series
For standardized frame structures, consider:
EK&EG PRO Series Subracks – Ideal for general industrial use
EK+&EG+ PRO Series Subracks – Optimized for the Chinese market
Shielded Plug-in Units Series Subracks – Designed with EMC shielding for sensitive electronics
Each series comes with compatible side panels, front/rear panels, handles, and fasteners.
3. Add Essential Rack Accessories
To complete your rack, include:
Panels – Aluminum-magnesium or sheet metal
Handles/fasteners – To secure PCB cards
Rails and backplanes – For multi-card configurations
Plastic connector blocks – For insulation where needed
Explore Rdekono’s extensive accessories catalog to simplify design and ensure compatibility.
4. Ensure EMC Shielding and Ventilation
In high-EMC environments, use:
Conductive gaskets, metallic panels
Ventilated covers or fans for airflow
Heat sinks or heat pipes for thermal management
Shielded series racks come pre-equipped with EMC-friendly components.
5. Use Modular Assemblies for Faster Delivery
Rdekono’s rack solutions are modular—you can build:
Single-PCB housings with minimal parts: side panels, front plate, top cover, handles, fasteners
Multi-PCB enclosures using card guides, connector blocks, backplanes, gaskets
Custom variants to meet your unique I/O or backplane requirements
This modularity accelerates validation and reduces design complexity.
For single-PCB encapsulation, the module rack requires only side panels, a front panel, handles, a cover plate, and fasteners to secure the PCB.
For multi-PCB encapsulation, additional components such as internal PCB guide rails and intermediate connectors are needed. Plastic connector blocks may also be used for insulated PCB mounting.
Standard module rack heights include 3U and 6U, with widths aligned to standard panels (5.08mm = 1TE = 1HP). The minimum width is 5 HP.

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;
