25×25mm Compact Aluminum Electronic Enclosure for Optoelectronic Device

Compared to plastic housings, aluminum alloy enclosures offer superior structural strength and a premium metallic finish. Additionally, CNC machining allows for the customization of features such as interface cutouts, mounting holes, threaded holes, and slots. The compact 25×25mm profile is particularly well-suited for products such as PCB control modules, communication modules, sensors, data acquisition devices, IoT terminals, small controllers, and electronic instruments.

Key Product Advantages

01 Compact Structure

The 25×25mm cross-section is ideal for electronic products with strict size constraints.

For devices housing PCBs, circuit modules, or small electronic components, this compact aluminum enclosure helps minimize the product's overall footprint.

02 Extruded Aluminum Profile Construction

The main body of the enclosure is formed through aluminum alloy profile extrusion.

While the cross-sectional dimensions remain fixed, the length can be cut to meet specific product requirements, allowing a single enclosure specification to accommodate PCBs and electronic modules of varying lengths.

This structure is particularly suitable for electronic product lines requiring series-based development.

03 Suitable for PCB Mounting

The enclosure can be designed with internal mounting slots or support structures to secure PCBs and other electronic components.

This design simplifies internal mounting arrangements and ensures a stable fit between the PCB and the enclosure.

04 Supports CNC Customization

Standard profiles are just the starting point.

Boyuan Hardware offers CNC machining services for the 25×25mm aluminum enclosure based on customer drawings, including:

• Interface cutouts
• Screw holes
• Threaded holes
• Positioning holes
• Grooves
• Steps
• Counterbores
• Chamfers
• Other custom features

05 Customizable Length

While 25×25mm defines the cross-sectional specification, the product length can be cut to match the actual dimensions of the device. Therefore, it can be used for PCBs and electronic modules of varying lengths without requiring a redesign of the housing structure for each specific length.

The specific machinable length is determined based on the material, surface finish, and product requirements.

06 Metal Housing: Balancing Structure and Aesthetics

Aluminum alloy offers lightweight properties and excellent structural integrity while retaining a natural metallic texture.

Surface treatments such as brushing, sandblasting, and anodizing allow for diverse visual effects, giving small electronic devices a professional appearance.

Technical Specifications

Note: Specific material grades, wall thicknesses, length ranges, dimensional tolerances, and surface finish colors are subject to actual product drawings and order requirements.

Suitable Applications

The 25×25mm profile is a compact aluminum housing specification, making it ideal for small electronic modules and PCB-based products rather than large equipment chassis.

1. PCB Electronic Modules

This is a typical application for the 25×25mm aluminum housing.

Suitable for:

• PCB control modules
• Data acquisition modules
• Control circuit modules
• Small electronic controllers
• Embedded electronic modules

The aluminum profile body can be cut to match the PCB length and then enclosed using end caps.

2. IoT Devices

Suitable for small IoT terminals and communication modules, such as:

• IoT control modules
• Data acquisition terminals
• Wireless communication modules
• Remote monitoring modules
• Smart sensor nodes

The compact 25×25mm structure facilitates the design of miniaturized devices.

3. Communication Modules

If a standalone protective housing is required for small communication modules, the 25×25mm aluminum housing serves as a compact solution.

CNC machining can be performed to accommodate the module's interfaces and mounting requirements. Examples include:

• Communication modules
• Signal conversion modules
• Data transmission modules
• Small-scale network modules
• Wireless communication terminals

4. Sensors and detection modules

The compact 25×25mm housing is suitable for small-sized units such as:

• Industrial sensor modules
• Data acquisition modules
• Measurement modules
• Electronic detection modules
• Environmental monitoring modules

The final dimensions depend on the size of the internal PCB and electronic components.

5. Industrial control modules

Suitable for small industrial control and automation electronic modules, such as:

• Control modules
• I/O modules
• Signal conversion modules
• Data acquisition modules
• Small controllers

For internal equipment installation, mounting holes or other structural features can be machined according to the specific installation location.

Customization Options

Surface Treatment

Anodizing

Anodizing is a common surface treatment for aluminum housings; it alters the surface appearance and properties while allowing for various color finishes.

Sandblasting

Sandblasting creates a uniform matte texture on the aluminum surface, making it ideal for industrial electronic equipment and instrument housings.

Brushed Finish

Brushing creates a regular metallic grain, preserving the distinct metallic look and feel of the aluminum alloy.

Laser Engraving

The following can be engraved on the aluminum housing surface:

• Logos
• Product models
• Interface labels
• Serial numbers
• Text and graphics

Screen Printing

Suitable for multi-colored logos, text, and functional markings.

Professional Custom Aluminum Housing Fabrication

We not only manufacture the standard 25×25mm Compact Aluminum Electronic Enclosure for Optoelectronic Device but also offer customization based on your product's specific structure.

Simply provide us with:

• 2D drawings
• 3D models
• Physical samples
• Product dimensions

We will then evaluate the manufacturing requirements based on your specific product needs.

CNC Machining for Non-Standard Requirements

For products that cannot be accommodated by the standard 25×25mm profile alone, customization can be achieved through subsequent CNC machining.

Features such as:

• Interface cutouts
• Mounting holes
• Threaded holes
• Grooves
• Steps
• Logos

...can all be machined according to customer drawings.

Product Selection Guide

If your PCB width is close to 25mm

Consider the 25×25mm specification first, then verify the structural fit based on PCB thickness, mounting method, and the height of internal components.

If PCB lengths vary

There is no need to switch to a different specification; the aluminum profile can be cut to the required length.

If interface installation is required

CNC cutouts can be added to the main profile body or the end plates.

Common examples include USB ports, RJ45 jacks, power connectors, other connectors, indicator lights, etc.

If PCB installation is required

Internal slots, mounting holes, or other fixing methods can be determined based on the PCB design.

If 25×25mm is too small

You can select a larger aluminum profile specification based on the PCB dimensions or opt for a custom (non-standard) enclosure design.
