Input Connector(s): Voltage Rating 30V DC

Component Specifications

Definition

Input connectors are critical interface components on frame grabbers and vision interface cards that establish physical and electrical connections between industrial cameras and computer systems. These connectors facilitate the transmission of digital image data, synchronization signals, and control commands at high speeds with minimal latency. They are engineered to maintain signal integrity in industrial environments with electromagnetic interference, vibration, and temperature variations. Common interface standards include Camera Link, CoaXPress, GigE Vision, and USB3 Vision, each with specific connector types optimized for different data rates, cable lengths, and environmental conditions.

Working Principle

Input connectors operate by providing a standardized physical interface that aligns with specific vision communication protocols. They contain precisely arranged pins or contacts that match corresponding connectors on camera cables. When mated, these contacts establish electrical pathways for differential signal pairs (for data transmission), power lines (for camera power over cable), and ground connections. The connector housing provides mechanical stability, shielding against electromagnetic interference, and environmental protection. Advanced connectors incorporate impedance matching, shielding layers, and locking mechanisms to ensure reliable high-speed data transfer up to several gigabits per second while withstanding industrial operating conditions.

Materials

Connector housing: Glass-filled PBT or PPS thermoplastic for dimensional stability and temperature resistance. Contacts: Gold-plated phosphor bronze or beryllium copper for optimal conductivity and corrosion resistance. Insulators: High-temperature thermoplastics with UL94 V-0 flame rating. Shielding: Nickel-plated steel or aluminum alloy. Sealing: Silicone rubber gaskets for IP67/IP68 rated connectors.

Frequently Asked Questions

What is the difference between Camera Link and CoaXPress connectors?

Camera Link uses MDR26 or MDR34 connectors with multiple data pairs for parallel transmission up to 850 MB/s. CoaXPress uses coaxial BNC or DIN 1.0/2.3 connectors with serial transmission over single cables, supporting longer distances (up to 100m) and higher speeds (up to 25 Gbps per link).

Can input connectors be hot-swapped during operation?

Most industrial vision connectors are not designed for hot-swapping. GigE Vision and USB3 Vision connectors may support limited hot-plug capability with proper implementation, but Camera Link and CoaXPress connectors should only be connected/disconnected with power off to prevent damage.

How do I choose the right input connector for my application?

Consider these factors: required data rate (resolution × frame rate), cable length, environmental conditions (temperature, vibration, contaminants), camera interface standard, and system compatibility. Camera Link suits high-speed applications with shorter cables; CoaXPress excels in long-distance transmission; GigE Vision offers cost-effective solutions; USB3 Vision provides plug-and-play simplicity.
