35mm Compact Aluminum Extrusion Chassis for Electronic Applications

This 35mm Compact Aluminum Extrusion Chassis for Electronic Applications adopts an aluminum profile structure. The height is fixed at 35mm, and the length and width can be customized according to PCB dimensions, internal component layout, and equipment installation requirements.

The chassis interior has PCB card slots and mounting grooves, used for PCB positioning as well as the mounting of internal electronic modules and structural parts. At the same time, the aluminum profile structure has a certain heat dissipation capability, meeting the structural support and basic heat dissipation needs of small electronic devices.

The compact 35mm height is suitable for electronic equipment that needs to control overall device volume while still requiring a certain amount of internal mounting space. By customizing the chassis length and width, the chassis dimensions can be made to fit the actual PCB and internal component layout more closely.

Product Structure

Structural Logic

35mm fixed height → length and width customization → PCB card slots → internal mounting grooves → heat dissipation structure → front and rear panel machining → chassis assembly

Core Advantages

1. 35mm Fixed Height, Balancing Compact Dimensions and Internal Space

The 35mm height maintains a relatively compact device profile, while providing more reasonable mounting space for PCBs and internal electronic components than extremely low-height chassis.

Suitable for products with requirements on overall device dimensions that still need a certain component layout space internally.

2. Length and Width Customizable to Actual Equipment

The core feature of this product is not a fixed length and width dimension, but rather:

Fixed 35mm height + customizable length + customizable width.

The chassis length and width can be determined according to the following factors:

• PCB dimensions
• Component layout
• Interface positions
• Number of internal modules
• Mounting method
• Overall device dimension requirements

This avoids wasting internal space to fit a standard chassis.

3. Built-In PCB Card Slots

The chassis interior is provided with PCB card slots, which can be used for circuit board positioning and mounting.

For electronic products that need to integrate the PCB directly into the aluminum profile chassis, the card slots help determine the PCB position and reduce the need for additional fixing structures.

4. Internal Mounting Grooves Support Flexible Layout

The internal mounting grooves can be used to mount different internal structural parts.

According to the product design, internal layout can be carried out around the PCB, electronic modules, and other components, making more rational use of the limited 35mm height space.

5. Aluminum Profile Structure Balances Support and Heat Dissipation

The aluminum profile body can provide a stable chassis structure, while aluminum itself has good thermal conductivity.

For small electronic devices, heat dissipation design can be carried out in combination with the profile structure and internal component layout.

6. Front and Rear Panels Machinable According to Device Interfaces

The front and rear panels can be CNC-machined according to the actual device structure, for example:

• Power interface holes
• USB interface holes
• Communication interface holes
• Indicator light holes
• Button holes
• Mounting holes
• Other special-shaped holes

This allows the chassis to match the interface layout of specific electronic devices.

Technical Specifications

Why Choose a 35mm Fixed Height?

For electronic device chassis, smaller is not always better.

If the chassis is too low, it may limit:

• PCB layout
• Component height
• Interface mounting
• Internal structural design
• Heat dissipation space

The 35mm height keeps the device compact while providing more generous layout space for internal PCBs and electronic components than ultra-low structures.

At the same time, length and width can be customized independently, so the chassis can be designed according to actual PCB dimensions, rather than having the PCB adapt to a fixed enclosure.

Applicable Fields

This 35mm Compact Aluminum Extrusion Chassis for Electronic Applications is recommended to focus on small, compact electronic devices requiring a certain amount of internal space, rather than broadly covering all industrial equipment.

1. Small Control Modules

Suitable for small control modules that need to integrate PCBs, control circuits, and interfaces into an independent chassis.

The 35mm height can reduce the overall space occupied by the device, while custom length and width match the internal circuit board.

2. Data Acquisition and Signal Processing Modules

For devices that need to install PCBs, interfaces, and data processing circuits, the internal card slots can be used for PCB positioning, and the interface layout can be completed through custom panels.

3. Communication Interface Devices

Suitable for small communication, signal conversion, and interface expansion devices.

The chassis length and width can be adjusted according to the number of interfaces, PCB dimensions, and mounting space.

4. Embedded Electronic Modules

Suitable for electronic modules that need to be installed inside other equipment, control cabinets, or limited mounting spaces.

The compact structure can help control the space occupied by the device while retaining necessary internal mounting space.

5. IoT and Smart Electronic Devices

For small IoT electronic devices that need to integrate PCBs, communication modules, power supplies, and external interfaces, the 35mm fixed height can achieve a balance between device dimensions and internal layout.
