XCMG XE2000 Excavator Connector (803103351): Ensuring Stable Connection for the Electrical System

In the intricate electrical network of the XE2000 large mining excavator, the reliability of the connectors directly affects the equipment’s operational precision and safety. XCMG’s original connector (part number: 803103351) is specially customized for this model, offering superior connection performance and weather resistance, making it a key component ensuring the efficient operation of the electrical system.

Ultra-precision contact ensures zero-loss signal transmission

The XE2000 excavator’s intelligent control system relies on the real-time transmission of numerous electrical signals, from engine condition monitoring to hydraulic action command execution. Any signal delay or attenuation can affect operational efficiency. This connector employs a modular pin design, achieving a contact precision of 0.01mm between the pins and the socket. Combined with a flexible contact structure, it maintains stable conductivity even under vibration. Whether transmitting high-frequency control signals or high-current power, it achieves low-impedance, interference-free, and efficient transmission, effectively avoiding problems such as delayed equipment response and false triggering caused by poor contact, ensuring accurate execution of control commands.

Military-grade protection to withstand multi-dimensional environmental challenges

The harsh environment of mining operations places extreme demands on the protective performance of connectors. The 803103351 connector shell adopts a combination structure of reinforced PA66 engineering plastic and zinc alloy inserts, with an impact resistance of up to 15kJ/m², capable of withstanding severe vibrations and accidental collisions during equipment operation. The internal contacts are made of high-purity copper, treated with multiple layers of nickel and gold plating, withstanding over 5000 mating cycles and a 60% improvement in oxidation resistance. Its overall sealing reaches IP6K9K protection level, completely resisting high-pressure water washing, oil immersion, and dust intrusion, and can still operate stably in an extreme temperature range of -40℃ to 105℃, adapting to various harsh mining environments.

Original factory calibration ensures 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 manufacturer. Designed for the machine’s 12V/24V mixed circuit system, its rated current reaches 15A, and its insulation resistance is ≥1000MΩ, perfectly matching the electrical requirements of key components such as the engine control module, hydraulic sensors, and operating handles. The installation interface strictly adheres to the original factory drawings, with a fit error of ≤0.05mm between the locating pin and the fixing hole. This allows for quick assembly without adjustment, ensuring seamless integration with the overall machine’s circuit system and avoiding the risk of circuit failures caused by parameter incompatibility with non-original parts.
