Industrial Camera Mount Types
The choice of industrial camera mount type is a critical consideration in designing a vision system, as it directly impacts factors such as stability, flexibility, and compatibility with other components. Industrial cameras can come with many different mount types, each with its own advantages and suitability for different applications.
Arguably the most prevalent mount type for industrial cameras is the C-mount, characterized by a 1-inch (or 25.4 mm) thread diameter and a 17.526 mm flange focal distance which is the distance from the joint of the camera and lens to the digital sensor. Since it is one of the most common mount types, C-mount cameras offer versatility and compatibility with a wide range of lenses, including auto-focusing lenses and other types of specialized optics. This flexibility allows for easy adaptation to different imaging requirements, such as variable working distances or field of view adjustments. Additionally, C-mount cameras are commonly used in machine vision applications due to their widespread availability and standardized interface, making them well-suited for integration into existing systems.
Another common mount type is the CS-mount, similar to the C-mount but with a shorter flange focal distance of 12.5 mm. CS-mount cameras are typically used in applications where space constraints or weight considerations are critical, as they allow for more compact camera designs. However, it is important to note that CS-mount cameras should not be paired with C-mount lenses unless an adapter is used to make up for the difference in back focal distance.
F-mount, a bayonet-style mount developed by Nikon for its 35 mm format cameras, is commonly used with larger sensors such as full-frame or line-scan cameras. While lenses can be easily swapped out thanks to the bayonet mount, back focal adjustment is not possible with this mount. Mxx-mounts, defined by their diameter (e.g. M72, M42), thread pitch (e.g. 1 mm, 0.75 mm) and flange focal distance, are another alternative to the F-mount for larger sensors.
For specialized applications, industrial cameras may utilize fixed mounts or custom mounting solutions tailored to specific environments or mounting requirements. Due to their custom nature, these types of mounts are much less versatile and are therefore less common.
In summary, the choice of industrial camera mount type is essential in designing a vision system optimized for performance, reliability, and adaptability to diverse application needs. Whether opting for the versatile C-mount, the compact CS-mount, or custom mounting solutions, selecting the appropriate mount type ensures seamless integration and optimal functionality of the industrial camera within the vision system.
