Product Advantages

01 | 52×19mm Wide and Slim Design

The 52mm wide × 19mm high cross-section size provides an ideal packaging solution for ultra-thin smart devices.

The 52mm width can accommodate standard wide PCB layouts and support side-by-side design of multiple interfaces and function modules; the 19mm thickness keeps the device slim while providing nearly 50% more internal space than the 13mm specification, allowing more components, taller parts, or better heat dissipation structures.

02 | Aluminum Extrusion Structure

The enclosure body is formed by aluminum alloy profile extrusion. The cross-section size of the aluminum extrusion enclosure is fixed, while the length can be cut according to actual product requirements. Therefore, the same specification enclosure can adapt to PCBs and electronic modules of different lengths.

03 | Suitable for PCB Mounting

The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior is standard-equipped with circuit board card slots, and the PCB can be directly inserted and fixed without additional screws.

04 | CNC Custom Machining Support

The standard profile is only the starting point. Boyuan Hardware can perform CNC machining on the 52×19mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, Type-C, DC power interfaces, etc.)
• Indicator light holes
• Button holes
• Mounting holes and positioning holes
• Threaded holes and counterbore holes
• Heat dissipation slots and ventilation structures
• Grooves and steps
• Chamfering
• Other custom structures

05 | Length Customizable to Product

52×19mm is the cross-section specification of the enclosure, and the product length can be cut according to the actual equipment dimensions. The specific machinable length is confirmed according to material, surface treatment, and product requirements.

06 | Optimized Heat Dissipation Performance

Aluminum alloy has excellent thermal conductivity. Combined with the 52mm wide-body design and 19mm height space, small heat sinks can be installed or internal air convection space can be increased. Compared with the 13mm ultra-thin specification, the 19mm height provides better heat dissipation conditions, making it more suitable for LED controllers and other devices with slightly higher power.

07 | Metal Enclosure Combines Structure and Appearance

Aluminum alloy is lightweight and has good structural performance, while retaining a natural metal texture. Through surface treatments such as brushing, sandblasting, and anodizing, different appearance effects can be obtained, giving ultra-thin devices a more refined product texture.

Technical Specifications

Note: Specific material grades, wall thickness, length ranges, dimensional tolerances, and surface treatment colors shall be subject to actual product drawings and order requirements.

What Products Is the 52×19mm Aluminum Enclosure Suitable For?

52×19mm belongs to the ultra-wide slim aluminum enclosure category — the 52mm width can accommodate standard wide PCBs and side-by-side layout of multiple function modules, and the 19mm height provides more ample internal space while maintaining a slim profile. The 19mm thickness offers nearly 50% more internal space than the ultra-thin specification, allowing devices to accommodate more components or achieve better heat dissipation while maintaining a slim profile.

1. LED Strip Controllers and Dimmers

52×19mm is an ideal packaging solution for LED strip controllers:

• LED strip controllers
• RGB/RGBW dimming controllers
