IV. 3-Step Quick Selection Technique

Step 1: Determine Interface Type Based on Transmission Need

• Relay control circuits: R4RC (only 1408976, 10m 93B) → relay module wiring;
• Open-circuit sensor/actuator signals: R4OC (BC5/BC6A coding, e.g., 1227560) → proximity/photoelectric sensor wiring;
• Advanced communication/fieldbus: R4ACS (93B/93C coding, e.g., 1112785) → high-reliability sensor networks;
• 10G high-speed Ethernet: R4AC-10G (94F coding, e.g., 1416125) → industrial cameras/large-data devices;
• Critical Ethernet circuits (visual identification): R4AC1 (BU blue, 94G coding, e.g., 1413160) → emergency communication links;
• Standard industrial Ethernet: R4AC/R4ACR (93B/93E/93M/94B coding, e.g., 1408970) → PLC/HMI/IO device networking.

Step 2: Match Cable Length to Installation Distance

• Ultra-short (compact cabinets): 0.3m (1422209) / 0.5m (1112785) → internal module-to-module wiring;
• Short-distance (cabinet internal): 1.0m (1227560) / 1.5m (1422211) → sensor-to-PLC wiring;
• Medium-distance (workstation): 2.0m (1227562) / 3.0m (1227563) / 5.0m (1112856) → production line device interconnection;
• Long-distance (workshop-wide): 7.5m (1424816) / 10m (1408976) / 15m (1227570) / 20m (1113327) → cross-workshop sensor/network wiring.

Step 3: Select Coding for Protocol Compatibility

• PROFINET: 93E coding (1408935 R4AC) → PROFINET IO device communication;
• 10G Ethernet: 94F coding (1416125 R4AC-10G) → high-bandwidth data transmission;
• Phoenix proprietary open-circuit: BC5/BC6A (1227560 R4OC) → matching Phoenix sensors/actuators;
• General signal/fieldbus: 93B coding (1112785 R4ACS) → most industrial control systems;
• Critical Ethernet (visual ID): 94G + BU blue (1413160 R4AC1) → emergency/key circuits;
• Custom protocol: 93M coding (1420383 R4ACR) → legacy/custom industrial devices.

V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Interface type mismatch: 10G Ethernet using R4AC (standard Ethernet) → Choose R4AC-10G (1416125) for 10G bandwidth support.
2. Coding incompatibility: PROFINET system using 93B coding → Select 93E coding (1408935 R4AC) for PROFINET protocol compatibility.
3. Cable length error: 20m workshop wiring using 5m cable → Opt for 10m/15m/20m models (1408976/1227570/1113327) to avoid signal attenuation.
4. Critical circuit identification missing: Emergency communication using black cables → Use R4AC1 (BU blue, 1413160) for visual differentiation.
5. Proprietary protocol neglect: Phoenix open-circuit sensors using 93B coding → Choose BC5/BC6A coding (1227560 R4OC) for matching sensor signals.
6. High-speed data oversight: Industrial cameras using standard Ethernet (R4AC) → Select R4AC-10G (1416125) for 10G high-bandwidth transmission.
7. Compact cabinet wiring error: 0.3m internal wiring using 1m cable → Use 0.3m (1422209) / 0.5m (1112785) models to save space and reduce cable clutter.
