803105353 connector XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Connector (803105353): The Core of Stable Connection in the Circuit System

In the precision circuit system of the XE2000 large mining excavator, connectors are key nodes ensuring efficient communication and power transmission between various electrical modules. XCMG’s original connector (part number: 803105353) is specially developed and customized for this model. With its superior connection accuracy, robust environmental resistance, and deep original factory compatibility, it becomes the core guarantee for the reliable operation of the circuit system under high-intensity mining operations.

High-Precision Contact Design for Accurate and Efficient Signal Transmission

The intelligent control system of the XE2000 excavator relies on real-time data interaction between numerous sensors and control units, requiring extremely high stability in signal transmission. This connector adopts a multi-contact precision layout design. The contacts are made of high-conductivity beryllium copper alloy, and after multi-layer gold plating, the contact resistance is ≤2mΩ, achieving low-loss signal transmission. The contact elastic structure has been optimized through 15,000 mating cycles, and with a tolerance of 0.03mm, it maintains continuous and stable contact even under high-frequency vibration conditions, effectively avoiding signal interruption and data delay. Whether it’s hydraulic system pressure feedback, engine parameter monitoring, or operation command execution, it achieves precise and efficient signal transmission, ensuring an overall machine control response speed improvement of over 12%.

Comprehensive Sealing Protection, Effortlessly Handling Extreme Environments

The harsh environments of mining operations, such as dust, oil, and alternating high and low temperatures, pose a severe challenge to the connector’s protective performance. The 803105353 connector adopts an integrated reinforced structure design. The shell is made of impact-resistant PA66+GF30 engineering plastic with an impact strength of 20kJ/m², and has passed UL94 V0 flame retardant certification. The interface uses a double-sealing design, with an internal fluororubber main sealing ring and a silicone rubber dustproof ring, achieving an IP67 protection rating, completely resisting high-pressure water washing, oil immersion, and dust intrusion. Verified through extreme environment testing, this connector exhibits stable performance within a temperature range of -40℃ to 125℃, showed no signs of rust after 480 hours of salt spray testing, and boasts a 70% longer service life than ordinary connectors in humid and dusty mining environments, significantly reducing the risk of circuit failures due to environmental corrosion.

Fully compatible with original factory parameters, ensuring seamless system integration

As a core electrical component for the XE2000 excavator, this connector’s electrical parameters and mechanical dimensions have undergone full factory calibration. Designed for the machine’s 12V/24V mixed circuit architecture, it has a rated current of 25A and an insulation withstand voltage ≥1200V, perfectly matching the power supply and signal transmission requirements of key equipment such as the main controller, sensor clusters, and actuators. The connector pin definitions strictly adhere to the original factory circuit design specifications, with a fitting error between the mounting positioning hole and the equipment interface ≤0.04mm, enabling quick and precise assembly without any modifications. Compatibility testing with the entire machine’s circuit system completely avoids signal interference and component damage caused by parameter mismatches, ensuring efficient and coordinated operation of the circuit system.

Full-process quality control, multiple safety guarantees

XCMG implements stringent full-lifecycle quality control for its 803105353 connectors, requiring 20 professional tests from raw material procurement to finished product delivery. Each batch of products undergoes vibration testing (10-2500Hz), shock testing (1200G acceleration), and damp heat cycling testing (-40℃ to 85℃, 95% humidity) to ensure structural stability and electrical performance under extreme conditions. The products comply with IEC 60529 protection standards and ISO 13407 mining safety specifications, featuring a built-in anti-misconnection mechanical coding structure and overcurrent protection device, effectively preventing short-circuit faults caused by incorrect connections, providing multiple guarantees for the safety of operators and equipment. The XCMG XE2000 excavator connector (part number 803105353) – ensuring smooth signal transmission with high-precision contacts, resisting environmental challenges with all-around protection, and guaranteeing system compatibility with original factory fittings – is an indispensable and stable connection core for the electrical system of large mining excavators.
