Allen-Bradley 1485T-P2T5-T5 1485 DeviceNet Media T-Port Connector

The Allen-Bradley 1485T-P2T5-T5, also cataloged as the 1485T-P2T5-T5 DeviceNet T-Port Tap Connector, operates as a dedicated hardware component for establishing drop connections from DeviceNet trunk lines within DeviceNet network architectures. It maintains signal integrity and supplies 24 VDC at 4 A to downstream nodes while enabling secure device integration.

Hardware Specifications

DeviceNet Branch Connectivity

The 1485T-P2T5-T5 provides a physically keyed T-port interface that ensures proper orientation when connecting drop cables to the main trunk. The connector supports full current and voltage ratings for downstream nodes, preventing communication interruptions. Watertight sealing and rugged molded housing provide mechanical protection and environmental resilience in industrial settings.

Frequently Asked Questions

Q: Can the T-Port connector handle 15 A total current as stated in the application note?
A: The connector supports 24 VDC at 4 A per drop; cumulative current must be managed according to DeviceNet network design limits.

Q: Are the connectors compatible with all 1485 Thick Round Media cables?
A: Yes, the T-Port is compatible with DeviceNet Thick Round Media cables using 5-pin mini-style terminations.

Q: Is the T-Port connector suitable for outdoor installations?
A: Yes. When fully assembled, the connector meets NEMA 4, 6P, and IP67 environmental standards.

Field Installation Guidelines

Ensure trunk and drop cables are routed without sharp bends or mechanical stress. Fully seat all 5-pin mini-style connectors into keyed ports to maintain electrical and signal continuity. For watertight performance, verify that the housing seal engages correctly. Avoid tension or kinking on cables during installation. Maintain minimum bend radius as specified for DeviceNet Thick Round Media cabling. Confirm drop connections do not exceed individual drop current ratings to prevent voltage drop or network errors.
