Description

Phoenix SFNT14TX/2FX Ethernet Switch

Product Overview

The Phoenix Contact FL SWITCH SFNT 14TX/2FX (Order No. 2891954) is an unmanaged industrial Ethernet switch engineered for extreme industrial environments. The designation “SFNT” indicates that this unit belongs to the Standard Function Narrow Temperature Extreme series, designed with a extended operating temperature range (-40 °C to +75 °C) and a narrow aluminum housing.

It features 14 twisted-pair copper RJ45 ports (10/100 Mbps) and 2 multi-mode fiber optic (FX) ports with SC duplex connections (100 Mbps). It provides high port density and noise-immune optical backbone connectivity in harsh industrial enclosures.

Technical Specifications

Key Advantages

• Extreme Temperature Resilience: Built to operate reliably in harsh outdoor cabinets or unconditioned environments ranging from -40 °C to +75 °C.
• Noise-Immune Fiber Backbone: Dual multi-mode SC fiber optic ports provide long-distance transmission while immunity to high electromagnetic interference (EMI/RFI).
• High Density in Narrow Footprint: Provides 16 total network ports within a narrow 70 mm aluminum housing, optimizing cabinet DIN-rail space.
• Unmanaged Plug-and-Play Setup: Auto-negotiation and auto-crossing (Auto-MDI/MDIX) across all copper ports eliminate the need for crossover cables or complex software configuration.
• Redundant Power & Alarm Contact: Dual power inputs (12–48 V DC) with a built-in alarm relay trigger immediate notification if a power supply fails.

Important Usage & Installation Precautions

• Fiber Optic Cable Matching: Ensure multi-mode optical fiber cables (50/125\,\mum or 62.5/125\,\mum) with SC connectors are used. (Single-mode fiber is not compatible with FX multi-mode ports).
• Power Supply Polarity: Verify proper DC voltage polarity before powering the unit. Use both US1 and US2 terminals with independent power supplies for maximum redundancy.
• Shielding & Grounding: Connect the switch’s grounding terminal directly to the DIN rail or cabinet PE ground to ensure full protection against electrostatic discharge (ESD) and surge interference.
• Cabinet Ventilation: Maintain a minimum 50 mm clearance above and below the switch inside the enclosure to facilitate natural convection cooling.
• Hazardous Location Wiring: When deploying in Class I, Division 2 environments, follow NEC / CEC rules for hazardous location wiring and terminal connection integrity.

Applications

• Outdoor & Traffic Management Control: Roadside cabinets, intelligent transportation systems (ITS), and railway monitoring where ambient temperatures fluctuate drastically.
• Energy & Power Substations: Renewable energy farms (wind turbines, solar power stations) requiring EMI-resistant fiber optics for long distances.
• Water & Wastewater Treatment: Centralized networking for distributed PLC clusters and remote terminal units (RTUs).
• Factory Automation Backbones: High-density port aggregation for SCADA systems, IP video surveillance cameras, and machine-side control panels.
