Allen-Bradley 1786-TPS ControlNet Coaxial T-Tap Straight Connector

Product Overview

The 1786-TPS serves as a fundamental connection node within a ControlNet coaxial media system. This T-Tap provides the physical interface required to drop a node from the trunk cable to a specific device, such as a PLC processor or communication adapter. It features a straight BNC connector and a 1-meter drop cable, facilitating high-speed, deterministic data transmission across the network. We supply this unit as 100% Brand New original stock, ensuring signal integrity and impedance matching for your mission-critical ControlNet architecture.

Technical Specifications

The 1786-TPS integrates seamlessly into industrial coaxial networks with the following specifications:

• Network Protocol: ControlNet

• Tap Type: Coaxial T-Tap (Straight Connector)

• Connection Type: BNC

• Drop Cable Length: 1 Meter (3.3 feet)

• Mounting Options: Surface Mount, Fixture Mount, or DIN Rail

• Weight: 0.20 lbs (0.09 kg)

• Construction: Industrial-grade shielded coaxial assembly

Engineering Advantages

• Optimized Signal Integrity: The 1786-TPS maintains the 75-ohm impedance required for ControlNet specifications. This precision prevents signal reflections and data collisions, ensuring the deterministic performance of your distributed I/O and peer-to-peer messaging.

• Versatile Mounting Flexibility: The housing supports multiple installation methods, including DIN rail and direct surface mounting. This allows engineers to secure the tap in crowded control cabinets or directly onto machine frames, preventing cable strain and connector fatigue.

• Plug-and-Play BNC Interface: The straight BNC connector provides a secure, twist-lock connection that withstands industrial vibrations. This locking mechanism solves the problem of intermittent connectivity often found with standard push-on connectors in high-movement manufacturing zones.

• Pre-Terminated Drop Cable: The factory-installed 1-meter drop cable eliminates the need for field termination of the drop line. This reduces installation time and removes the risk of improper shielding or poor crimping that often leads to network noise and intermittent faults.

FAQs

• Is the 1786-TPS supplied as a brand new original part?

  Yes. We offer this product strictly as 100% Brand New original stock. Each tap remains in its factory-original condition to guarantee maximum network reliability and signal throughput.

• What is the difference between the 1786-TPS and the 1786-TPR?

  The 1786-TPS features a Straight BNC connector on the drop cable, whereas the 1786-TPR uses a Right-angle connector. Choose the 1786-TPS for installations where the cable enters the device perpendicular to the port, providing a cleaner vertical run in deep cabinets.

• How many 1786-TPS taps can I use on a single ControlNet segment?

  ControlNet supports up to 99 nodes per segment. Each node requires a tap (like the 1786-TPS). Ensure you install 75-ohm terminators (1786-XT) at both physical ends of the trunk cable to prevent signal bounce, regardless of the number of taps used.

• Does this tap require a separate mounting kit?

  No. The 1786-TPS includes integrated mounting hardware that clips directly onto a standard DIN rail or screws onto a flat surface. This built-in design simplifies the bill of materials and accelerates the assembly of your network infrastructure.
