44×25mm Aluminum Communication Equipment Housing

44×25mm Aluminum Communication Equipment Housing — a compact extruded aluminum enclosure that sits between ultra-slim and taller profile options. Its 25mm height gives noticeably more internal clearance than 13mm, 18mm, or 23mm versions, allowing the housing to accept taller plug-in components, terminal blocks, connectors, switches, and small modules.

At the same time, the 44mm width supports convenient lateral arrangement of PCBs, sockets, indicators, and communication or power ports. This balance makes it a practical choice for electronic modules that demand both a small footprint and reasonable component space.

Product Definition

The 44×25mm aluminum enclosure is a compact electronic device enclosure designed with an extruded aluminum structure, with an external size of approximately 44mm × 25mm. Compared to thinner low-profile aluminum enclosures, this size provides more ample internal height for PCBs, circuit components, connectors, and interface layouts while maintaining a small overall volume.

Its 44mm lateral dimension is suitable for PCB and interface layout, and the 25mm height can accommodate relatively abundant electronic components. Therefore, it is more suitable for electronic modules that have certain requirements for volume, structural strength, electronic component mounting space, and heat dissipation conditions.

Through processes such as cutting, drilling, tapping, end face machining, interface openings, surface treatment, laser engraving, and silkscreen printing, it can be machined into different lengths and mounting forms according to actual product structures.

Core Advantages

1. 44mm Width, Balancing PCB and Interface Layout

The 44mm lateral space is more generous than ultra-narrow electronic enclosures and can be arranged according to PCB dimensions:

• Terminal blocks
• Sockets
• Switches
• Indicator lights
• Buttons
• Communication interfaces
• Power interfaces
• Sensor interfaces

For electronic modules that need to centrally arrange multiple interfaces on the enclosure end face, the 44mm width provides more flexible structural design space.

2. 25mm Height, Better Internal Component Capacity

The 25mm height provides greater internal space than low-profile specifications such as 13mm, 18mm, and 23mm.

Therefore, it is not only suitable for thin PCBs, but also more suitable for installing electronic components with a certain height, such as:

• PCB through-hole components
• Terminal blocks
• Connectors
• Small modules
• Switches and buttons
• Power-related components
• Electronic components requiring a certain mounting height

For products that cannot use ultra-thin enclosures, 44×25mm can serve as a more balanced size choice.

3. Aluminum Extrusion Structure, Suitable for Electronic Product Enclosures

Aluminum extrusion enclosures have good structural stability while maintaining relatively low overall weight, suitable for electronic equipment that needs repeated installation, disassembly, or long-term use.

The profile structure also facilitates cutting according to product length, and combined with end plates, screws, and CNC machining, forms a complete electronic device enclosure.

4. Suitable for Product Series of Different Lengths

For the same series of electronic equipment, if different models have different PCBs or numbers of internal components, different specifications can be formed by adjusting the aluminum profile length.

For example:

• Short length → small electronic modules
• Medium length → PCB + interfaces + control components
• Longer length → more circuits and connection components

This allows multiple product models to be developed using the same or similar enclosure cross-section, reducing the cost of redesigning the enclosure.

Technical Specifications

Note: Specific aluminum alloy grades, wall thickness, internal structure, length ranges, machining tolerances, and surface treatment colors need to be confirmed according to actual drawings or product requirements.

FAQ

Q1: Is the 44×25mm aluminum enclosure suitable for installing PCBs?

Yes. This size can be used for electronic products such as PCBs, control boards, communication modules, and data acquisition modules. Whether it is specifically suitable needs to be confirmed according to PCB dimensions, component height, and mounting method.

Q2: What is the difference between 44×25mm Aluminum Communication Equipment Housing and 44×23mm?

Both have the same width, and the main difference is in height. 44×25mm adds about 2mm of height compared to 44×23mm, so the internal component mounting space is relatively more ample, and it is more suitable for electronic equipment containing components with a certain height, such as terminal blocks, connectors, and switches.

Q3: Can the length of the 44×25mm aluminum enclosure be customized?

Length machining can be performed according to product structure and aluminum profile machining requirements. The actual machinable length needs to be confirmed in combination with specific product and order requirements.

Q4: Can interface holes such as USB and RJ45 be machined?

CNC opening machining can be performed according to customer drawings and interface dimensions. The specific hole positions, dimensions, and structures need to be confirmed at the drawing stage.

Q5: Can threaded holes be machined?

Yes. Drilling, tapping, and other machining can be performed according to the product mounting method.

Q6: Can a logo be made on the aluminum enclosure?

Logo and product identification machining such as laser engraving or silkscreen printing can be performed according to customer requirements.

Q7: Can you machine a complete electronic device enclosure?

Yes. We can complete cutting, CNC machining, surface treatment, logo machining, inspection, and related assembly processes around the aluminum extrusion enclosure.

Q8: What if I don't know which aluminum enclosure size to choose?

You can first provide PCB dimensions, maximum internal component height, interface positions, and the required external dimensions of the product. We can help confirm the appropriate profile specification based on these structural parameters.

What to Provide When Purchasing a 44×25mm Aluminum Enclosure?

To quickly confirm product manufacturability, customers are advised to provide the following information:

If you currently only have a PCB or product prototype and no complete enclosure drawing, you can also start by confirming the product dimensions and internal structure.
