Description: A PLC connector harness is a pre-wired cable assembly used to connect I/O modules, power supplies, sensors, actuators, and communication interfaces to a Programmable Logic Controller.

• Purpose: Reliable signal and power transmission between PLC and field devices
• Common Connectors:
  • DIN connectors (e.g., 20-pin or 40-pin for I/O modules)
  • M8/M12 circular connectors (for sensors/actuators)
  • Terminal blocks (screw, spring clamp)
  • RJ45 (for Ethernet/IP communication)
• Key Features:
  • Shielded wiring for noise immunity
  • Color-coded wires per IEC standards
  • Ferrules and strain relief for durability
  • Pre-terminated for quick installation
• Applications: Industrial automation, manufacturing lines, process control systems
• Standards: IEC 61131, UL, CE, IP67 (for rugged environments)

Note: Always verify pinout compatibility with specific PLC models (e.g., Siemens S7, Allen Bradley CompactLogix, Mitsubishi FX).
