IV. 3-Step Quick Selection Technique

Step 1: Select the Right Series Based on Application

• General Industrial Connectivity: Choose standard FLK 50/EZ-DR/KONFEK series (e.g., 2289094 for 2m connections)
• Harsh Environments: Opt for FLK 50/EZ-DR/.../S series (e.g., 2299123 for 2m high-protection needs)
• Heavy-Duty Applications: Use FLK 50/4X14/EZ-DR series (e.g., 2296728 for 3m power transmission)
• DeltaV Process Control: Select FLK 50/2FLK20/EZ-DR/DV series (e.g., 2304911 for 3m DeltaV systems)
• PLC Front Adapter Connections: Pick FLK 50/EZ-DR/.../40RVS series (e.g., 2290546 for 2m PLC connections)
• Specialized Controller Integration: Choose manufacturer-specific variants (D37SUB for Mitsubishi, FCN40 for Omron)

Step 2: Determine the Appropriate Length

• Cabinet-Internal Wiring: 0.5m–2.0m (50–200)
  • Example: 2289065 (0.5m) for compact control cabinet connections
• Machine-to-Machine Connections: 3.0m–8.0m (300–800)
  • Example: 2289641 (8.0m) for production line equipment linking
• Cross-Department/Workshop: 10.0m (1000) standard maximum
  • Example: 2289683 (10.0m) for long-distance factory automation

Step 3: Add Special Features as Required

• Enhanced EMI Protection: Choose variants with additional shielding (S suffix)
• High-Vibration Environments: Select heavy-duty 4X14 variants or S-protected cables
• Custom Terminations: Use OE (open-ended) variants (e.g., 2295758) for field-specific adaptations
• Controller Compatibility: Match connection type to controller brand (e.g., DV for DeltaV, D37SUB for Mitsubishi)

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Incorrect Length Estimation:

   • Issue: Underestimating required length leads to cable strain or replacement costs
   • Solution: Always add 10-15% extra length for routing flexibility and movement allowance

2. Environmental Mismatch:

   • Issue: Standard cables fail in harsh conditions (vibration, moisture, chemicals)
   • Solution: Use S-suffix variants (e.g., 2299107) or 4X14 heavy-duty series for demanding environments

3. Interface Compatibility Error:

   • Issue: Mismatched connectors prevent system integration
   • Solution: Verify controller interface requirements and select appropriate connection type (e.g., 40RVS for PLC front adapters)

4. Current Capacity Insufficiency:

   • Issue: Standard cables overheat under high load
   • Solution: Use 4X14 heavy-duty variants (e.g., 2296744) for power transmission applications

5. DeltaV System Specific Errors:

   • Issue: Non-DV variants fail in DeltaV DCS systems
   • Solution: Always use FLK 50/2FLK20/EZ-DR/DV series (e.g., 2304937) for DeltaV environments

6. Unnecessary Cost:

   • Issue: Over-specifying cables for simple applications
   • Solution: Match series to application needs—standard KONFEK series is sufficient for most industrial applications
