Allen-Bradley 1786-BNC ControlNet Coaxial BNC Connector

The Allen-Bradley 1786-BNC is a precision-engineered coaxial BNC connector designed specifically for ControlNet network infrastructure. This industrial-grade termination component ensures reliable, high-speed data transmission across distributed control systems in demanding manufacturing environments.

Technical Specifications

Catalog Number: 1786-BNC
Connector Type: Coaxial BNC (Bayonet Neill oncelman)
Network Compatibility: ControlNet Media Interface
Impedance: 75 Ohm characteristic impedance
Cable Type: RG-6 coaxial cable compatible
Contact Material: Gold-plated brass for superior conductivity
Operating Temperature: 0 °C to 60 °C (32 °F to 140 °F)
Mounting: Bayonet twist-lock mechanism

Application Scenarios

Process Automation Networks: Deploy the 1786-BNC in pharmaceutical, food & beverage, and chemical processing plants where ControlNet provides deterministic, repeatable communication between PLCs, I/O modules, and HMI stations.

Automotive Assembly Lines: Integrate into robotic welding cells and conveyor control systems requiring synchronized motion control and real-time data exchange across multiple zones.

Power Generation Facilities: Connect turbine control systems, SCADA interfaces, and safety instrumented systems (SIS) where network reliability directly impacts operational uptime.

Solutions & Benefits

Deterministic Performance: ControlNet’s scheduled communication ensures predictable data delivery ritical for coordinated motion applications and time-sensitive process control.

Noise Immunity: Coaxial design with 75-ohm impedance matching minimizes electromagnetic interference (EMI) in electrically noisy industrial environments.

Quick Installation: Bayonet coupling allows tool-free connection and disconnection, reducing installation time by up to 40% compared to threaded connectors.

Long-Term Durability: Gold-plated contacts resist corrosion and oxidation, maintaining signal integrity over 10+ year service life in harsh conditions.

Integration & Compatibility

The 1786-BNC seamlessly integrates with Allen-Bradley ControlLogix, CompactLogix, and FlexLogix platforms. Pair with 1786-RG6 coaxial cable, 1786-TPS taps, and 1786-XT terminators to build robust, redundant ControlNet trunk lines supporting up to 99 nodes per segment.

Typical System Architecture: Use in star, tree, or linear topologies with maximum trunk length of 1000 meters (3280 feet) at 5 Mbps data rate. Supports both scheduled and unscheduled messaging for mixed I/O and peer-to-peer communication.
