Did You Use the Module Rack Correctly?

l What is a Module rack?

A module rack is primarily used to encapsulate PCB boards in plug-in units that comply with specific standards such as IEC 60297 and GB19520. Its functions are reflected in the following aspects:

u 1. Physical Protection : The module case provides a robust enclosure for PCB boards, shielding them from physical damage such as impacts, scratches, or dust.

u 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.

u 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.

u 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.  

u 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.

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.

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. 

BEIJING RDEKONO Electronic Equipment Co., Ltd. offers compatibility services for module racks from multiple international brands, primarily using aluminum-magnesium alloy and sheet metal structures. Additionally, the company can design and produce custom module racks tailored to customer requirements.
