Allen Bradley 1786-BNCP ControlNet Coaxial Barrel Connector

Product Overview

The Allen Bradley 1786-BNCP serves as a specialized barrel connector designed for high-performance ControlNet coaxial media systems. This plug-to-plug TNC coaxial adapter facilitates the extension and seamless coupling of ControlNet cables without compromising signal integrity. We supply these connectors in 100% Brand New original condition, ensuring your industrial network maintains the 5 Mbps deterministic communication speed required for ControlLogix and PLC-5 architectures.

Technical Specifications

This connector utilizes precision-engineered TNC (Threaded Neill–Concelman) interfaces to provide a secure, low-loss connection for industrial RG-6 quad-shielded cables.

Engineering Advantages

• Superior Signal Continuity: The 1786-BNCP minimizes signal attenuation at junction points. This maintains the strict 75-ohm impedance required across the ControlNet trunk, preventing data packet drops and network jitter.

• Vibration-Resistant Threading: The TNC threaded design offers significant mechanical advantages over standard BNC bayonet mounts. The threads lock the connection in place, preventing signal interruptions in high-vibration environments near heavy rotating machinery.

• Corrosion-Resistant Plating: High-grade metallic plating protects the contact surfaces against industrial atmospheric contaminants. This ensures a low-resistance electrical path over long-term deployments in harsh factory floor conditions.

• Rapid Network Extension: These barrel connectors allow technicians to extend existing cable runs instantly. This eliminates the need for expensive and time-consuming cable re-pulls when moving or expanding I/O racks.

FAQs

• Can I use the 1786-BNCP for standard 50-ohm BNC applications?

  No. The 1786-BNCP features TNC threading specifically designed for 75-ohm ControlNet RG-6 coaxial systems. Standard BNC connectors use a different locking mechanism and may not provide the necessary impedance matching, leading to signal reflections.

• How tight should I secure the TNC threads?

  Finger-tighten the connector until it seats firmly. Avoid using heavy pliers, as excessive torque can deform the internal dielectric and change the impedance of the connection, negatively impacting network performance.

• Are these connectors compatible with redundant media?

  Yes. You can use the 1786-BNCP on both Trunk A and Trunk B of a redundant ControlNet system. Using original Allen Bradley connectors ensures that both paths maintain identical electrical characteristics for seamless failover.

• Does this part number include 50 individual connectors?

  The 1786-BNCP typically ships as a bulk pack of 50 units. This allows for large-scale installation and provides maintenance teams with sufficient spares for emergency repairs and network reconfigurations.
