48×33mm Aluminum Communication Device Enclosure

The 33mm height accommodates PCBs, connectors, terminal blocks, power modules, and other components with moderate height, while the 48mm width supports larger boards and multi-port arrangements. It targets electronic equipment that needs real internal mounting space, several interfaces, and structural strength, yet does not justify a large aluminum chassis.

The profile body can be cut to length and finished with end plates, CNC machining, mounting holes, interface openings, threaded holes, logos, and surface treatment. Boyuan Hardware, with over 20 years of experience and a ~10,000㎡ factory, handles cutting, three-axis CNC, drilling, tapping, surface treatment, laser engraving, silkscreen, inspection, and assembly.

Product Definition

The 48×33mm Aluminum Communication Device Enclosure is an extruded aluminum electronic device enclosure with relatively ample internal space, with a cross-section size of approximately 48mm × 33mm.

Compared to low-profile specifications such as 19mm, 23mm, and 25mm, the 33mm height provides more ample mounting space for PCBs, connectors, terminal blocks, power modules, and other electronic components with a certain height. At the same time, the 48mm width can also meet the layout requirements of larger PCBs and multi-interface structures.

Therefore, this specification is more suitable for electronic equipment that has certain requirements for internal mounting space, number of interfaces, and structural strength, but does not want to use a large aluminum chassis.

Typical applications include:

• Industrial control modules
• Data acquisition equipment
• Communication equipment
• Signal conversion equipment
• Measurement and test equipment
• Power and control modules
• IoT and embedded electronic devices
• Small instruments and equipment

The aluminum profile body can be cut according to product length, and combined with end plates, CNC machining, mounting holes, interface openings, threaded holes, logo, and surface treatment to form a complete electronic device enclosure.

Core Advantages

1. 33mm Height, Providing More Ample Internal Component Space

The most obvious feature of 48×33mm is its 33mm cross-section height.

Compared to low-profile aluminum enclosures, it can accommodate more electronic components with a certain height, so it is not limited to thin PCBs.

For example:

• Terminal blocks
• Connectors
• Switches
• Power modules
• PCB through-hole components
• Small control modules
• Communication modules
• Sensor and interface components

For electronic products with relatively complex internal structures, the 33mm height provides greater design margin.

The actual usable internal height still needs to be confirmed according to the profile wall thickness and specific cross-section structure.

2. 48mm Width, Suitable for PCB and Multi-Interface Layout

The 48mm width provides larger lateral space than narrower cross-sections such as 35mm, 38mm, and 40mm.

Therefore, it can more flexibly arrange: PCB + terminal blocks + interfaces + control components.

For products that need to set multiple interfaces on the end face or side, it can also provide better opening layout space.

3. Balanced Dimensions, Suitable for Compact Electronic Devices

48×33mm is not a large chassis specification, but a size between small electronic modules and larger electronic equipment.

It is suitable for electronic products that:

• Need more internal space than low-profile enclosures
• Do not need a large chassis
• Need to install multiple electronic components
• Need multiple external interfaces
• Want to keep the overall product compact

Therefore, this size is especially suitable as an aluminum enclosure for small industrial electronic equipment and control equipment.

4. Suitable for Product Series of Different Lengths

The aluminum profile cross-section remains unchanged, and different product models can be formed simply by adjusting the length according to the internal PCB and number of components.

For example:

• Short version → small control modules
• Medium length → PCB + interfaces + control components
• Longer version → data acquisition, communication, or multi-interface devices

For the same product series, this can reduce the need to redevelop enclosures with different cross-sections.

Technical Specifications

Specific parameters such as aluminum alloy grade, profile wall thickness, internal dimensions, length range, machining tolerances, and surface treatment colors shall be subject to actual product drawings and order requirements.

Application Scenarios

1. Industrial Control Modules

48×33mm has larger internal space than low-profile enclosures, so it is suitable for some small industrial control equipment.

For example:

• Industrial Control Modules
• Control Interface Modules
• I/O Modules
• Embedded Controllers
• Industrial Electronic Controllers

If PCBs, terminals, connectors, and control components need to be installed internally at the same time, 48×33mm can provide more ample structural space.

2. Data Acquisition and Measurement Equipment

Data acquisition equipment usually needs to install PCBs, signal interfaces, terminal blocks, and other electronic components.

The 48mm width can satisfy relatively rich lateral layout, and the 33mm height can accommodate components with a certain height.

Suitable for:

• Data Acquisition Modules
• Data Acquisition Equipment
• Measurement Modules
• Signal Processing Modules
• Sensor Interface Devices

3. Signal Conversion Modules

Signal conversion products may require multiple input/output interfaces and internal circuit boards.

48×33mm can provide relatively ample mounting space for PCBs and interfaces.

For example:

• Signal Conversion Modules
• Signal Interface Modules
• Industrial Signal Converters
• Communication Interface Devices

4. Industrial Communication and Network Equipment

For small communication equipment that needs to install communication interfaces, PCBs, and related electronic components, a 48×33mm aluminum extrusion enclosure can be used.

Suitable for:

• Communication Modules
• Industrial Communication Devices
• Data Transmission Equipment
• Network Interface Modules
• Embedded Communication Electronics

5. Small Power and Control Modules

Compared to low-profile electronic enclosures, the 33mm height provides more internal mounting space, so it can also be used for some small power and control electronic products.

For example:

• Power Control Modules
• Electronic Power Modules
• Control Units
• Power Interface Modules

Whether it is specifically suitable needs to be confirmed according to internal component dimensions and heat dissipation requirements.

6. Test and Measurement Instruments

48×33mm can be used for some small test and measurement electronic equipment.

For example:

• Electronic Test Modules
• Measurement Devices
• Signal Testing Equipment
• Monitoring Equipment
• Laboratory Electronics

If the product requires a display, multiple interfaces, or a relatively complex internal circuit, this size also provides more structural space than ultra-thin enclosures.
