1205351

Overview

Phoenix Contact part number 1205351 is a passive RJ45 port bridge adapter designed for network connectivity expansion. The device features three parallel female RJ45 (8p8c) connectors, allowing multiple Ethernet devices to share a single upstream port. It supports Cat2 cable specifications and operates as an unshielded component. The unit includes provisions for optional functional grounding to ensure signal integrity and safety in industrial environments.

Feature Summary

• Passive RJ45 distribution architecture enabling connection of multiple downstream devices to a single upstream port
• Three parallel female connector interfaces for simultaneous multi-device attachment
• Supports optional functional grounding configuration for enhanced operational stability

Applications

• Industrial Ethernet network topology expansion
• Connecting multiple peripheral devices to a single switch port
• Temporary or permanent multi-node network bridging in controlled environments

Procurement Notes

Verify the specific product datasheet to confirm current manufacturing status and technical compliance before integration. Ensure that the passive nature of the bridge aligns with your network's bandwidth and collision domain requirements. Confirm that the Cat2 specification meets your application's data rate needs. Check for any regional regulatory certifications required for deployment.

Selection Notes

Select this component when a passive solution is sufficient for sharing a single Ethernet link among multiple devices. Consider the Cat2 limitation if higher data rates are required. Evaluate the need for functional grounding based on the installation environment. This adapter is suitable for low-speed or control network segments where active switching capabilities are not necessary.

Part Context

This adapter belongs to Phoenix Contact's range of modular and Ethernet connectors, specifically designed for industrial automation and communication networks. It complements their broader portfolio of COMBICON series PCB connectors and CONNEXIS crimping systems, providing physical layer connectivity solutions for reliable data transmission in demanding settings.

Replacement Considerations
