Subracks, or rack-mounted enclosures, are vital for organizing and securing electronic equipment within telecom, defense, industrial, and IT sectors. Ordering the right subrack involves considering multiple factors, from size and material to customization options and industry standards. This guide provides a quick overview of key aspects to consider, ensuring you select a subrack that meets your specifications and operational needs.
First, define the primary purpose of the subrack. Subracks can hold various electronic equipment, such as circuit boards, power supplies, and connectors, within a safe, organized, and accessible structure. Determine the specific types of equipment you plan to house, as well as any environmental or functional requirements, to ensure the subrack supports your equipment adequately.
1. Equipment Type: For delicate circuit boards, select subracks that provide enhanced protection and shock resistance. For network devices, choose subracks with sufficient airflow to prevent overheating.
2. Environment: If the equipment will be exposed to extreme temperatures or vibrations, select a subrack with durability features like reinforced construction and ventilation options.

Subracks come in various sizes, typically measured in units (U), with a standard width of 19 inches for compatibility with most racks. Selecting the right size involves knowing the height and depth requirements of your equipment. Also, determine whether you need front mounting, rear mounting, or a combination, as different applications may require specific mounting styles.
1. Height (U): The height of the subrack should accommodate the number of components you plan to house. Standard heights are 1U, 2U, 3U, and higher, with each "U" representing 1.75 inches.
2. Depth: Ensure the depth of the subrack matches your equipment specifications, as some devices may require additional space for cabling or airflow.
3. Mounting Style: Select the appropriate mounting style based on your equipment setup and space availability. Front mounting is common for easy access, but some setups may require rear mounting for additional stability.
The material of the subrack affects its durability, weight, and resistance to environmental conditions. Common materials include aluminum, stainless steel, and plastic. Each material has specific benefits and drawbacks, so consider your application and environment when selecting the material.
1. Aluminum: Lightweight and corrosion-resistant, aluminum subracks are suitable for many general applications and provide good thermal conductivity.
2. Stainless Steel: Stainless steel offers enhanced durability and resistance to extreme temperatures, making it ideal for demanding environments but generally comes at a higher cost.
3. Plastic: Lightweight and cost-effective, plastic subracks work well for low-stress environments, but they may lack the durability required for high-impact or high-temperature settings.
Customization can be critical for subracks, particularly if you have specialized equipment or specific functional needs. Customization options may include additional cutouts, paint finishes, handles, shock mounts, and EMI (Electromagnetic Interference) shielding. Many suppliers offer these options to ensure your subrack meets your unique requirements.
1. Cutouts and Slots: Custom cutouts for cabling or additional slots can improve organization and accessibility, reducing clutter and easing maintenance.
2. EMI Shielding: For sensitive equipment, EMI shielding can protect against electromagnetic interference, which can disrupt electronic performance.
3. Paint and Finish: Choose paint finishes that provide corrosion resistance and blend with other equipment aesthetics. Consider color options that suit your brand or organizational preferences.
Industry standards help ensure that subracks meet specific safety, durability, and performance criteria. Standards like IEC 60297 and IEEE 1101 set guidelines for the design, size, and mounting specifications of subracks. Checking compliance with these standards can simplify installation and guarantee compatibility with your existing equipment.
1. IEC 60297: This standard specifies dimensions and mounting methods for 19-inch subracks, ensuring compatibility across different manufacturers.
2. IEEE 1101: This standard provides guidelines for mechanical and electrical compatibility for VPX, VMEbus, and other modular equipment, making it essential for certain industrial and defense applications.
Q: How do I determine the right size for my subrack?
Assess the height (U), width, and depth of the equipment to be housed. Ensure the subrack has sufficient clearance for cabling, airflow, and maintenance.
Q: What are the main benefits of aluminum subracks?
Aluminum subracks are lightweight, corrosion-resistant, and provide good thermal conductivity. They are also easy to handle and install, making them suitable for general applications.
Q: Are custom subracks more expensive than standard models?
Customization may add to the cost depending on the modifications required. However, the added functionality and fit can often justify the expense for specialized applications.
Choosing the right subrack involves understanding your specific equipment needs, environment, and customization requirements. By following these tips, you can ensure your subrack offers the durability, functionality, and organization needed to enhance your operations.

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;
