Dongfeng KR truck parts Vehicle networking communication terminal with bracket assembly 7920805-C5102

Built as the “data hub” for Dongfeng KR’s vehicle networking, the terminal supports dual-mode 4G LTE (B1/B3/B5/B7/B8/B38/B40/B41) and Beidou/GPS dual positioning, ensuring uninterrupted connectivity even in remote areas. The 4G module achieves download speeds up to 150Mbps and upload speeds up to 50Mbps, enabling real-time transmission of 100+ vehicle parameters (fuel consumption, engine speed, tire pressure) to the IFMS. When 4G signals are weak (-115dBm), it automatically switches to Beidou short message service for emergency data reporting. The GPS/Beidou positioning accuracy reaches ±1m (CEP), with a refresh rate of 1Hz, supporting precise fleet tracking, route optimization, and anti-theft monitoring for logistics operations

The terminal’s integrated bracket is a standout feature, engineered to secure the device and protect it from truck vibration and environmental damage. The bracket is made of Q235 carbon steel with a 2mm-thick base and reinforced ribs, achieving a tensile strength of 375MPa—withstanding 20g vibration loads (5-2000Hz, ISO 16750-3) without deformation. A 3mm-thick EPDM rubber pad between the terminal and bracket absorbs 60% of shock, preventing internal component damage. The bracket’s open design ensures optimal heat dissipation for the terminal, while its pre-drilled M6 mounting holes align with the dashboard’s original threaded points, avoiding extra drilling. This integrated design reduces installation time by 40% compared to separate terminal and bracket setups

The terminal features industrial-grade hardware and multi-layer safety mechanisms to ensure long-term reliability. Its main control chip is a Qualcomm MDM9207, a automotive-grade processor with low power consumption and high stability, supporting 24/7 continuous operation. Internal circuits use high-temperature resistant capacitors (operating range -40℃ to 125℃) and gold-plated connectors (pull-out force ≥150N) to resist corrosion and signal loss. Safety protections include over-voltage (≥32V), under-voltage (≤18V), over-current, and short-circuit safeguards, automatically cutting off power to avoid damage. The terminal housing is IP67 waterproof/dustproof, with a flame-retardant ABS+PC shell (UL94 V-0 rating), ensuring safety in rainy, dusty, or high-temperature engine compartments

Optimized for fleet operational efficiency, the terminal integrates multiple intelligent functions and user-friendly maintenance features. It supports remote diagnostics via the IFMS, allowing technicians to read fault codes, update firmware, and adjust parameters without on-site access—reducing maintenance costs by 35%. The terminal also enables geofencing, idle monitoring, and driver behavior analysis (harsh acceleration/braking), helping fleet managers optimize fuel efficiency and safety. Installation is tool-free for basic setup: the bracket secures with 4 bolts, and the connectors plug directly into the wiring harness. Each unit undergoes 100% factory testing (communication stability, vibration resistance, waterproof performance) and comes with a 2-year/200,000km warranty, ensuring reliable support for long-haul logistics
