The choice between steel shell and plastic shell endoscope camera modules depends on the working environment, mechanical requirements, protection needs and device integration design.
Steel shell structures are often considered for inspection equipment and applications requiring stronger mechanical protection, while plastic shell structures may be suitable for projects where lightweight design and compact integration are priorities.
For OEM device developers, the right structure should be selected based on the complete system requirements, including diameter limitation, working environment, cable design, illumination configuration and expected device usage.
The camera head is usually installed in a narrow and complex environment.
During actual operation, the module may face:
mechanical contact
bending or movement
moisture exposure
repeated insertion
limited installation space
Therefore, the shell design is not only a mechanical component.
It directly affects:
protection capability
reliability during operation
integration flexibility
suitability for different applications
Steel shell structures are commonly considered when the camera module requires additional mechanical protection.
Typical application considerations include:
industrial inspection equipment
pipe inspection cameras
machinery inspection tools
environments with higher mechanical stress
The metal structure can provide additional protection for internal optical and electronic components.
This can be valuable when the camera head may experience:
collision
friction
repeated insertion
For industrial inspection applications, steel shell structures are often combined with sealing designs.
Depending on project requirements, waterproof protection such as IP67-level design can be evaluated.
When the camera module is connected with a long cable or inserted into deep structures, mechanical stability becomes more important.
Plastic shell structures may be considered when:
weight reduction is important
the application environment is controlled
compact device integration is required
Typical applications include:
portable visualization devices
compact inspection equipment
development prototypes
Consideration | Steel Shell | Plastic Shell |
|---|---|---|
Mechanical protection | Higher protection capability | Suitable for lighter applications |
Weight | Generally heavier | Lightweight |
Industrial environment | Often suitable for demanding inspection conditions | Suitable for controlled environments |
Integration flexibility | Depends on structure design | Flexible for compact designs |
Waterproof design | Can be evaluated with sealing structure | Depends on overall design |
Typical application | Industrial inspection, harsh environments | Portable and compact devices |
Engineers usually focus on:
compact size
imaging consistency
illumination
device integration
The shell selection depends on the final device structure and application requirements.
Engineers usually focus on:
mechanical protection
waterproof requirements
cable durability
inspection environment
Steel shell structures are often considered when the camera needs to operate in more challenging environments.
Choosing a suitable endoscope camera module requires evaluating the complete system:
The shell structure must match the available installation space.
Direct-view or side-view designs may be required depending on inspection requirements.
LED quantity and configuration affect visibility in dark cavities.
USB, Type-C, AV and customized interfaces should match the host system.
Consider:
Steel Shell camera modules
Waterproof-supported designs
Side-view structures
Long cable options
Suitable for:
pipe inspection
machine inspection
maintenance tools
Consider:
Lightweight camera structures
Small diameter modules
USB/UVC solutions
Suitable for:
portable inspection devices
compact visualization equipment
For different device requirements, customization can be evaluated for:
shell structure
diameter
lens configuration
LED arrangement
cable length
connector type
viewing direction
To select a suitable endoscope camera module, provide:
Information | Why It Matters |
|---|---|
Application | Determines structure requirement |
Working environment | Defines protection needs |
Diameter limitation | Determines mechanical design |
Viewing direction | Defines optical structure |
Interface | Ensures system compatibility |
Cable requirement | Supports device integration |
Waterproof requirement | Evaluates protection design |
Not necessarily. Steel shell is more suitable when mechanical protection is important, while plastic shell may better fit lightweight and compact device designs.
Waterproof capability depends on the complete structural design. For suitable projects, waterproof protection requirements can be evaluated.
Industrial inspection equipment often considers steel shell structures because they can provide additional mechanical protection in demanding environments.
Yes. Shell structure, diameter, cable and interface options can be evaluated according to OEM project requirements.
Not always. The suitable structure depends on the device design, application environment and integration requirements.
