73.5mm Extruded Aluminum Industrial Electronics Chassis

73.5mm Extruded Aluminum Industrial Electronics Chassis adopts an aluminum profile structure. The chassis height is fixed at 73.5mm, and the length and width can be customized according to the equipment internal space, PCB dimensions, and mounting requirements. The front and rear panels can be CNC-machined according to equipment interfaces and operation requirements, with interface openings, mounting holes, threaded holes, and other structures, so that the chassis can match specific electronic equipment.

Product Structure

Core Advantages

1. 73.5mm Fixed Height, Suitable for More Complex Internal Structures

Compared with low-profile chassis such as 30mm and 35mm, the 73.5mm height offers more ample vertical mounting space and can accommodate more internal electronic components.

It is especially suitable for industrial electronic equipment that needs to simultaneously install PCBs, electrical components, connectors, and internal cabling.

2. Length and Width Customizable to Requirements

The product height is fixed at 73.5mm, but the length and width can be designed according to the customer's equipment dimensions.

The appropriate chassis length and width can be determined according to:

· PCB dimensions

· Internal component layout

· Interface positions

· Mounting space

· Overall equipment dimensions

3. Built-In PCB Card Slots

PCB card slots can be designed inside the chassis to provide positioning and support for circuit boards, enabling the PCB to be mounted more stably inside the chassis.

For industrial electronic equipment containing multiple PCBs or requiring fixed circuit board positions, this structure is especially convenient.

4. Internal Mounting Grooves for Convenient Component Layout

The internal mounting grooves can be designed in coordination with the equipment internal structure, used to mount or fix different electronic components.

Compared with a simple cavity-type chassis, this structure is more suitable for electronic equipment requiring internal modular layout.

5. Aluminum Profile Structure Balances Structural Support and Heat Dissipation

Aluminum profile has good structural strength and thermal conductivity, and can serve as structural support for electronic equipment while assisting internal heat conduction.

For industrial electronic equipment that needs to work for long periods, corresponding heat dissipation structures can be designed in combination with the internal component layout.

6. Front and Rear Panels Can Be CNC-Machined

According to equipment interfaces and operation requirements, the front and rear panels can be CNC-machined, including:

· Interface openings

· Mounting holes

· Threaded holes

· Button holes

· Indicator light holes

· Display area

· Other custom openings

This allows the chassis to match the interface layout of the actual electronic equipment.

Technical Specifications

Why Choose a 73.5mm Height?

73.5mm is not simply an increase in chassis height, but is more suitable for industrial electronic equipment with more complex internal structures.

Compared with lower-height aluminum profile chassis, 73.5mm Extruded Aluminum Industrial Electronics Chassis can provide more ample internal vertical space, without changing the structural form of the aluminum profile chassis, offering more space for the following designs:

· Combined mounting of multiple PCBs

· Simultaneous mounting of PCBs and other electronic modules

· More connectors and interfaces

· Internal cable routing

· Spatial layout between electronic components

· Internal mounting brackets

· Electronic components requiring a certain heat dissipation space

Therefore, this 73.5mm chassis is more suitable for industrial electronic equipment with more functional modules and more complex internal structures.

Applicable Fields

Compared with the 70mm industrial control chassis, this 73.5mm product is not limited to "industrial control" itself, but is more suitable as a general-purpose chassis platform for industrial electronic equipment.

1. Industrial Electronic Control Equipment

Suitable for industrial electronic equipment internally containing control boards, interface modules, and multiple electronic components.

The 73.5mm internal height can provide more ample mounting space for control boards and other components.

2. Industrial Data Acquisition and Processing Equipment

Suitable for data acquisition, signal processing, data communication, and similar equipment.

For equipment that needs to install PCBs, interface modules, and internal connection structures, the chassis length and width can be customized according to PCB dimensions.

3. Industrial Communication Equipment

Suitable for industrial communication, interface conversion, and communication control electronic equipment.

The front and rear panels can be custom-machined according to the layout of RJ45, serial ports, communication interfaces, and other connectors.

4. Automation Equipment Electronic Modules

Can serve as an independent electronic control module or function module chassis in automation equipment.

The internal card slots and mounting grooves can help different electronic components be laid out according to the equipment structure.

5. Signal Processing and Electronic Modules

Suitable for signal processing equipment that needs to install multiple electronic modules, PCBs, and connectors internally.

Compared with low-height chassis, 73.5mm can provide more internal space, facilitating more complex module combinations.

6. Industrial Electronic Instrument Equipment

For equipment that needs to integrate circuit boards, interfaces, and internal electronic components into an independent chassis, device integration can be achieved through custom length and width and panel openings.
