In industrial automation networks, from basic device interconnection to high-speed gigabit transmission and three-layer routing, reliable Ethernet switches are the backbone of stable data exchange. The Phoenix FL SWITCH series expands its portfolio with SF (basic Fast Ethernet), SFN (gigabit versatile), MCS (compact Fast Ethernet), MM HS (high-speed fiber), and PMRA (three-layer routing) sub-series, covering from entry-level to high-end industrial network needs. With industrial-grade durability, flexible port combinations, and protocol compatibility, this series is widely used in factory automation, energy, logistics, and other fields. This guide integrates part number-model correspondence, core technical parameters, and scenario-specific recommendations to simplify selection and procurement, helping you quickly lock in optimal network solutions.

I. Core Advantages: Why Choose the Phoenix FL SWITCH Series?

• Full-speed coverage: Supports Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (1000 Mbps), adapting to low/high-bandwidth transmission needs.
• Diverse port configurations: Combines twisted-pair (TX/GT) and fiber (FX/SX/LX) ports, with single-mode (LX) transmission up to 20 km, multi-mode (SX) up to 550 m, meeting long/short-distance requirements.
• Industrial-grade reliability: Operating temperature range of -40°C to +70°C, IP20 protection, anti-vibration and electromagnetic interference (EMC compliance), suitable for harsh factory environments.
• Protocol & function optimization: PROFINET-optimized (PN suffix), diagnostic functions (DM suffix), three-layer routing (L3 suffix), and AC/DC power supply options, enhancing system adaptability.
• Flexible installation: DIN rail mounting, compact design (MCS series), and plug-and-play non-managed design (most models) for quick deployment.

III. 3-Step Quick Selection Technique (Easy for Beginners)

Step 1: Select Sub-Series Based on Speed & Scenario

• Basic low-bandwidth (10/100 Mbps): Entry-level needs, cost-sensitive → SF series (e.g., 2832771).
• Compact high-density (10/100 Mbps): Space-constrained control cabinets → MCS series (e.g., 2832700).
• High-bandwidth (1000 Mbps): Gigabit transmission, video + control integration → SFN series (e.g., 2891398).
• High-speed fiber backbone: Gigabit fiber transmission → MM HS series (2832328).
• Complex three-layer networks: Multi-subnet routing, large-scale enterprise → PMRA series (1087060).

Step 2: Confirm Port Type & Quantity

• Copper wire (short distance): TX (10/100 Mbps) or GT (1000 Mbps) ports; confirm device count (e.g., 5 devices → 5TX/5GT models, 16 devices → 16TX models).
• Fiber (long distance):
  • Multi-mode (≤550 m): SX ports (e.g., 2891398).
  • Single-mode (≤20 km): LX/LX-20 ports (e.g., 2891563 for 20 km).
  • Legacy systems: ST interface (e.g., 2832577); new systems: SC interface (default).
• Port density: High-device scenarios → 16TX/15TX models (e.g., 2891933), small-scale → 4TX/5TX models (e.g., 2891152).

Step 3: Check Special Requirements

• Protocol compatibility: PROFINET systems → PN-suffix models (2891151).
• Diagnostics: Fault monitoring needs → DM-suffix models (2891154).
• Power supply: AC-powered sites → 24VAC models (2891021); DC is standard.
• Redundancy: Critical networks → dual/multi-fiber ports (e.g., 2891935 with 2FX).
• Legacy integration: ST fiber interfaces → ST-suffix models (2832577).

IV. Recommended Industry-Scenario Combinations (Ready-to-Use)

V. Selection Pitfall Avoidance Guide (Common Mistakes to Note)

1. Speed mismatch: High-bandwidth applications (video + control) using Fast Ethernet (TX) models → Select Gigabit (GT/SX/LX) models (e.g., 2891398) to avoid bottlenecks.
2. Fiber type error: Single-mode fiber using multi-mode (SX) models → Match LX/LX-20 (single-mode) or SX (multi-mode) to fiber type; otherwise, transmission fails.
3. Protocol neglect: PROFINET systems using non-PN models → Choose PN-suffix (2891151) for Conformance-Class A compatibility.
4. Space constraint oversight: Compact cabinets using standard-size models → Opt for MCS series (2832700) to save 40% space.
5. Power supply error: AC-powered sites using DC-only models → Select 24VAC-suffix (2891021) to avoid module damage.
6. Redundancy missing: Critical networks using single-fiber ports → Choose dual-fiber (2FX) models (e.g., 2891935) for backup links.
7. Three-layer routing needs: Complex networks using non-L3 models → Only PMRA series (1087060) supports three-layer routing; other models are L2.

Conclusion: Select the Right FL SWITCH for Stable Industrial Networking

The Phoenix FL SWITCH SF/SFN/MCS/PMRA series covers entry-level to high-end industrial network needs, from basic Fast Ethernet to Gigabit transmission, compact design to three-layer routing.
