Order now 1786-BNCP to achieve professional-grade termination for your ControlNet coaxial infrastructure. The Allen-Bradley 1786-BNCP is a high-quality BNC male plug designed specifically for termination on RG-6 quad-shielded coaxial cable. In an industrial ControlNet environment, the quality of the connector is the single most important factor in preventing signal noise. The 1786-BNCP is engineered to meet the strict 75-ohm requirements of the Rockwell Automation communication standards. It features a robust crimp-style design that provides a 360-degree shield connection, which is vital for preventing electromagnetic interference from entering the data stream. By using this genuine Allen-Bradley component, you ensure that your network meets the factory-certified specifications for return loss and signal attenuation, providing the deterministic performance necessary for high-speed PLC-to-PLC and PLC-to-I/O communications.
What Is the 1786-BNCP?
The 1786-BNCP is the standard male BNC connector used to terminate ControlNet trunk and drop cables. It consists of a center pin, the main connector body, and a crimp ferrule. Unlike standard «twist-on» connectors which are prone to failure under vibration, the 1786-BNCP’s crimp design creates a permanent, gas-tight mechanical bond. This is essential in environments like automotive assembly lines or milling centers where constant vibration can loosen inferior connections. The gold-plated center pin ensures maximum conductivity, while the nickel-plated outer shell provides a durable interface for taps (1786-TPS) and repeaters (1786-RPCD).

High-Performance Network Termination
Proper termination with the 1786-BNCP is the foundation of a healthy ControlNet network. ControlNet uses a 5 Mbps Manchester-encoded signal that is highly sensitive to discontinuities in the cable. A poorly installed connector can cause «reflections» where the signal bounces back from the end of the cable, interfering with new data packets. The 1786-BNCP is designed to maintain the exact geometry of the coaxial cable through the connector, ensuring a smooth transition for the signal. This is why Rockwell Automation specifies the use of this specific plug along with the 1786-CTK crimp tool to ensure network certification.
Installation Advice
When installing the 1786-BNCP, the strip length of the coaxial cable is critical. Use the stripping tool from the 1786-CTK kit to ensure the center conductor, dielectric, and shield are cut to the exact lengths required. An installation tip from experts: before crimping the ferrule, ensure that no strands of the outer braid are touching the center conductor. Even a single microscopic hair-like wire can cause a short circuit that will bring down the entire network segment. After crimping, always perform a continuity test using a digital multimeter to ensure there is zero ohms from pin to pin and infinite resistance between the center pin and the outer shell.
Frequently Asked Questions
Q: Can I use a standard RG-6 BNC connector used for cable TV?
A: No. Standard CATV connectors are often not designed for the specific quad-shielding thickness of 1786-RG6 cable and may not provide the necessary EMI shielding or 75-ohm precision required for industrial data protocols.
Q: Is the center pin on the 1786-BNCP soldered or crimped?
A: The center pin is designed to be crimped using the precision die in the 1786-CTK tool kit, which provides a more reliable connection than soldering in high-vibration industrial settings.
