1786-BNCP | Allen-Bradley | ControlNet RG-6 Coaxial BNC Plug

Allen-Bradley 1786-BNCP Series B ControlNet BNC Coaxial Connector

Product Overview

The 1786-BNCP (Series B) is a high-precision ControlNet coaxial connector engineered by Rockwell Automation. This BNC plug is specifically designed to terminate RG-6 quad-shield coaxial cables, which serve as the primary media for ControlNet networks. The 1786-BNCP ensures high-integrity signal transmission and robust mechanical stability within distributed I/O systems and PLC-to-device communication links. Featuring a nickel-plated brass housing and a gold-plated center pin, it is built to withstand the electromagnetic interference (EMI) and vibration levels common in demanding industrial environments.

Key Functional Features

• Optimized Signal Integrity: The 1786-BNCP is designed for the RG-6 quad-shield cable architecture, providing the necessary shielding to prevent data corruption in high-noise factory settings.

• Series B Enhancements: As a Series B component, this connector features refined tolerances and improved plating durability for long-term reliability compared to legacy Series A versions.

• High Environmental Tolerance: With a broad operating temperature range and corrosion-resistant nickel plating, the module is suitable for use in unconditioned outdoor enclosures or heavy industrial processing plants.

• Low Loss Interface: Low insertion loss allows for longer cable runs within a single ControlNet segment before a repeater is required.
