Phoenix CABLE Series Industrial Connection Cables Selection Guide

Opening: Pre-Terminated Cables for Reliable Controller-I/O & Device Interconnection

The Phoenix CABLE series covers factory-pre-terminated industrial connection cables for linking controllers, I/O modules, and field devices, including FLK (FLK50/20/16/14/10), FCN40 (controller-specific), and DB37F (D-sub interface) sub-series. These cables feature fixed wire gauge (0.14mm²/0.4mm²/4×14/1×50), diverse lengths (0.05m–10m), and compatibility with mainstream controllers (Schneider M340, Siemens S7, Mitsubishi MEL), eliminating on-site wiring errors and improving connection stability. This guide organizes part number-model correspondence, core parameters, and scenario recommendations for efficient selection.

I. Core Advantages of the CABLE Series

1. Factory pre-terminated: Precision crimped and tested, reducing 80% of on-site wiring time and avoiding manual connection faults.
2. Controller-specific compatibility: Tailored for Schneider M340, Siemens S7, Mitsubishi MEL, and other mainstream PLCs, achieving plug-and-play integration.
3. Flexible length coverage: Ranges from ultra-short (50mm for cabinet internal) to long-distance (10m for field device connection), adapting to different installation spaces.
4. Stable signal transmission: Fixed 0.14mm²/0.4mm² signal wire gauge ensures low attenuation, while multi-core (4×14/1×50) power cables meet medium-current transmission needs.
5. Industrial-grade durability: Wear-resistant outer sheath, -25°C to +60°C operating temperature, and anti-vibration design for harsh factory environments.

III. CABLE Series Nomenclature Decoding

1. FLK Series Nomenclature

CABLE-FLK[Interface Size]/[Wire Gauge]/[Feature]/[Length]

• Interface Size: 50/20/16/14/10 → Matches FLK I/O module interface specifications (larger numbers for more cores).
• Wire Gauge: 0,14 → 0.14mm² signal wire for low-current data transmission.
• Feature:
  • OE = Open-end (for on-site terminal crimping);
  • HF = High-frequency (for high-speed signal transmission).
• Length: 50/200/300 (mm, without unit) or 2,0M/10,0M (meter, with M suffix), decimal separator is comma (European standard).

2. FCN40 Series Nomenclature

CABLE-FCN40/[Core Specification]/[Length]/[Controller Compatibility]

• Core Specification:
  • 4X14 = 4-core 14-gauge (multi-channel signal transmission);
  • 1X50 = 1-core 50-gauge (medium-current power supply).
• Length: 1,0M/2,0M/6,0M (meter).
• Controller Compatibility:
  • M340 = Schneider M340 PLC;
  • S7-OUT = Siemens S7 output module;
  • IM/MEL = Mitsubishi MEL input module.

3. DB37F Series Nomenclature

CABLE-DB37F-[Core Count&Type]/[Wire Gauge]/[Module Compatibility]

• Core Count&Type: 2IC14 = 2×IC14 dedicated signal cores.
• Wire Gauge: 0,4 = 0.4mm² signal wire (higher current than 0.14mm²).
• Module Compatibility: CS1112/CS1107 = Specific industrial control modules.

IV. 3-Step Quick Selection Technique

Step 1: Confirm Interface/Controller Type

• General FLK I/O modules: Select corresponding FLK sub-series (FLK50 for 50-pin modules, FLK14 for 14-pin modules) based on module interface size.
• Brand-specific PLCs:
  • Schneider M340 → FCN40 series with M340 suffix (e.g., 2321761 CABLE-FCN40/4X14/6,0M/M340);
  • Siemens S7 → FCN40 with S7-OUT suffix (2321185 CABLE-FCN40/4X14/1,0M/S7-OUT);
  • Mitsubishi MEL → FCN40 with IM/MEL suffix (2903470 CABLE-FCN40/1X50/2,0M/IM/MEL);
• D-sub 37-pin modules: Choose DB37F series (2903139/2903140) matching CS1112/CS1107 modules.

Step 2: Match Core Specification to Transmission Need

• Signal transmission: 0.14mm² (FLK series) or 0.4mm² (DB37F series) for low-current control/feedback signals; 4×14 (FCN40) for multi-channel signal integration.
• Power supply: 1×50 (FCN40 series) for medium-current I/O module power transmission (e.g., 2321664 CABLE-FCN40/1X50/3,0M/M340).

Step 3: Select Length Based on Installation Distance

• Cabinet internal (ultra-short): 50mm (2305761 FLK14) / 200mm (2305321 FLK20) to reduce cable clutter.
• Cabinet-to-I/O (short/medium): 0.5m (2318127 FLK16) / 2m (2314163 FLK50) / 3m (2318172 FLK16) for workshop local wiring.
• Field long-distance: 6m (2321761 FCN40) / 10m (2318211 FLK16) for cross-workshop device connection.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Interface size mismatch: FLK50 module using FLK14 cable → Confirm module interface size (50/20/16/14/10) to ensure physical compatibility.
2. Controller compatibility error: Siemens S7 using M340-suffix FCN40 cable → Select S7-OUT suffix (2321185) for S7, M340 suffix for Schneider systems.
3. Core specification error: Power supply using 4×14 signal cable → Choose 1×50 (FCN40) for power transmission to avoid overheating.
4. Length selection error: 10m field device using 2m cable → Opt for 10m (2318211 FLK16) or 6m (2321761 FCN40) to avoid signal attenuation from extended cables.
5. High-frequency signal neglect: High-speed communication using standard FLK cable → Select HF-suffix (2314163 FLK50/0,14/HF/2,0M) for stable high-frequency transmission.

Conclusion: Select the Right CABLE Series for Stable Industrial Interconnection

The Phoenix CABLE series provides pre-terminated, controller-compatible connection solutions for FLK I/O modules, brand PLCs, and D-sub interface devices, with flexible length and core specifications adapting to cabinet internal, workshop local, and field long-distance wiring.
