CoaXPress Frame Grabbers for Machine Vision

Welcome to this edition of the Clearview blog. This article will focus on machine vision frame grabbers using the CoaXPress platform.

We will discuss the advantages of CoaXPress interfaces and frame grabbers compared to other interfaces in the machine vision industry. We will also delve into the technical specifications of CoaXPress, highlighting the key features that make it a strong contender in the world of machine vision interfaces.

History of CoaXPress

CoaXPress (CXP) interfaces are high-performance alternatives to traditional interfaces like Camera Link and GigE. Known for their fast data transmission and long-distance capabilities, CoaXPress interfaces are increasingly popular in machine vision applications.

Established in 2007 by a consortium of companies in the machine vision industry, CoaXPress has become a widely adopted interface for high-speed data transmission in machine vision systems.

CoaXPress uses coaxial cables for data transfer

The development of CoaXPress was driven by the need for a high-speed, long-distance communication interface to meet the demands of modern machine vision applications. Before CoaXPress, machine vision systems often relied on limited-bandwidth parallel interfaces unsuitable for high-speed applications like automated inspection systems.

CoaXPress was designed to overcome these limitations and provide a flexible, scalable interface for machine vision systems. Its high-speed data transmission and long-distance capabilities have made it a popular choice for machine vision applications.

CoaXPress Frame Grabbers

CoaXPress frame grabbers are hardware devices that interface with machine vision cameras to transmit image data to a computer. They are designed to work with CoaXPress cameras using coaxial cables for high-speed data transmission.

These frame grabbers are commonly used in industrial automation, quality control, and inspection systems. They work with image processing software to analyze and interpret image data from the camera. Some CoaXPress frame grabbers offer additional features like FPGA-based image processing capabilities.

CoaXPress vs. GigE & USB Vision

CoaXPress is a superior alternative to GigE and USB vision interfaces. It can transmit data at faster speeds over longer distances using a simple coaxial interface. With CXP-6 delivering 6.25 Gbps per cable and CXP-12 offering 12.5 Gbps, CoaXPress outperforms GigE and USB 3.1 Gen1, as well as 10GigE and USB 3.1 Gen 2.
