XCMG XE2000 Excavator Connector (803012821): A Stable Connection Hub for the Circuit System

In the complex circuit system of the large mining excavator XE2000, the connector is the core node ensuring efficient transmission of electrical signals and power. XCMG’s original connector (part number: 803012821) is specially developed and customized for this model, offering superior connection precision, weather resistance, and reliability, making it a key guarantee for the stable operation of the circuit system under high-intensity mining operations.

Precision Contact Structure, Zero-Delay Signal Transmission

The intelligent control system of the XE2000 excavator relies on real-time communication between multiple sensors and control modules, requiring extremely high stability and timeliness in signal transmission. This connector adopts a pin-type precision contact design, with pins made of high-conductivity phosphor bronze. After gold plating, the contact resistance is ≤5mΩ, ensuring low-loss signal transmission. Combined with a flexible contact structure, it maintains stable contact even under severe equipment vibration, avoiding signal interruption or delay. Whether it’s engine speed regulation, hydraulic flow control, or operational command feedback, precise and efficient signal transmission is achieved, ensuring an overall machine control response speed improvement of over 10%.

Comprehensive protection design to withstand extreme environmental corrosion

In mining operations, connectors face multiple challenges, including dust contamination, oil immersion, and alternating high and low temperatures. The 803012821 connector shell is made of high-strength flame-retardant engineering plastic, certified by UL94 V0 flame retardant level, possessing excellent impact resistance and aging resistance. The interface adopts a double-sealing structure, with built-in fluororubber sealing rings and dust covers, achieving an IP6K9K protection rating, completely resisting high-pressure water jet washing and dust intrusion. After undergoing high and low temperature cycle testing from -40℃ to 125℃, it maintains stable performance even in the extreme temperature difference environment of mining areas, effectively avoiding poor contact or short circuit failures caused by environmental factors, extending its service life by 70% compared to ordinary connectors. Original Factory Calibration, Seamless System Compatibility

As a core component of the XCMG XE2000, this connector’s electrical parameters and mechanical dimensions have been precisely calibrated by the original factory. Designed for the machine’s 12V/24V mixed circuit system, its rated current reaches 20A, and its insulation voltage is ≥500V, perfectly matching the electrical requirements of key components such as the ECU control unit, hydraulic sensors, and audible and visual alarm devices. The modular design of the mounting positioning holes ensures a fit error of ≤0.03mm with the equipment’s circuit interface, allowing for rapid assembly without additional adjustments. Compatibility testing with the entire machine’s circuit system effectively avoids circuit interference or component damage caused by parameter mismatches, ensuring safe and stable system operation.

Rigorous Quality Testing, Comprehensive Safety Guarantee

XCMG implements full-process quality control for the 803012821 connector, requiring 16 rigorous tests from raw material intake to finished product delivery. Each batch of products undergoes vibration testing (10-2000Hz), shock testing (1000G acceleration), and salt spray testing (500 hours) to ensure structural stability and electrical performance under harsh working conditions. The products comply with ISO 8846 safety standards for marine electrical equipment and explosion-proof requirements for mining equipment, eliminating safety hazards such as leakage and sparks in humid and dusty environments, providing double protection for operator and equipment safety.

XCMG XE2000 excavator connector (part number 803012821) – ensuring smooth signal transmission with precision contact, resisting environmental challenges with comprehensive protection, and ensuring system compatibility with original equipment manufacturer (OEM) fitting, it is an indispensable and reliable connection hub for the electrical systems of large mining excavators.
