| Reference Number | Part Name | Description & Function |
|---|---|---|
| 1 | Main Multi-Pin Connector Block | Heavy-duty sealed connector housing with multiple terminal slots. Serves as the primary interface to the machine's ECU or main chassis harness. |
| 2 | Solenoid / Sensor Connectors | Individual branch-end connectors (DIN 43650 or similar). Attach directly to solenoid valves, sensors, or actuators on the equipment. |
| 3 | Protective Wire Loom (Conduit) | Flexible, abrasion-resistant corrugated tubing that encases and shields the internal wiring from heat, oil, moisture, and mechanical damage. |
| 4 | Copper Conductor Wires | Color-coded, multi-strand copper core wires that carry 24V DC power and control signals throughout the harness assembly. |
| 5 | Rubber Seals & Grommets | Molded rubber sealing elements integrated into each connector body. Provide IP-rated protection against water, dust, and vibration ingress. |
| 6 | Crimped Terminal Pins & Sockets | Precision brass or tin-plated terminals with positive locking tabs. Ensure secure, low-resistance electrical continuity at every connection point. |
| 7 | Branch Splice Junctions | Factory-sealed nodes where the main harness trunk divides into individual circuit legs for routing to different components. |
| 8 | Frame Mounting Clips & Brackets | Integrated plastic or spring-steel clips that anchor the harness securely to the machine's frame along the designated OEM routing path. |
