What is CoaXPress?

CoaXPress was developed in early 2007 as a response to the growing need for connecting advanced CMOS imaging technology while overcoming the limitations of existing Camera Link interfaces. This innovative standard offers significant advantages regarding bandwidth, cost efficiency, ease of implementation, and scalability.

The interface enables comprehensive management of digital video, control signals, triggering mechanisms, and power distribution through just one flexible cable solution that delivers both performance and cost savings.

Key Features

CoaXPress provides multiple configuration options to optimize various system requirements:

  • Bandwidth Options: Different versions address varying bandwidth needs
  • Cable Length Solutions: Flexible configurations for extended reach applications
  • Configuration Types: Dual and quad variants offer alternative solutions based on specific application requirements

Connector Options

The system supports two connector types:

  • BNC connectors
  • DIN 1.0/2.3 connectors

Note: Trigger input functionality is exclusively available with DIN 1.0/2.3 connectors.

Practical Applications

CoaXPress enables several innovative use cases in machine vision systems:

  • Rotary Applications: Ideal for slip ring installations where continuous rotation is required
  • System Upgrades: Facilitates seamless transitions from analog-based systems to digital solutions, as demonstrated with intelligent traffic monitoring systems
  • Multi-camera Systems: Enables efficient deployment of multiple cameras using a single frame grabber while minimizing CPU utilization

Performance Metrics

Demonstrations have shown exceptional performance characteristics:

  • Vision algorithms can maintain 95% CPU load efficiency while CoaXPress cameras operate independently at just 1% CPU usage
  • Complex installations with numerous cameras (exceeding 14 units) benefit from the system’s cable management capabilities, as evidenced by projects requiring extensive robotic coax cabling infrastructure
