803078015 XCMG GR2605 motor grader brake light pressure switch

803078015 XCMG GR2605 motor grader brake light pressure switch

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this product perfectly matches the model’s 194kW rated power output and 22MPa hydraulic braking system, precisely meeting the demands of harsh working environments such as mining, construction, and other dusty, vibrating, and flammable/explosive environments. It employs high-precision ceramic capacitive sensing elements, achieving a pressure detection accuracy of ±1.0% Vcc (0℃~80℃), with a 50% faster response speed than traditional mechanical switches. Pressure signal conversion and circuit switching are completed within 3ms, ensuring instant brake light activation and preventing misjudgment by following vehicles. The housing is made of SAE1022 carbon steel in one piece, with an anti-corrosion surface treatment and internal flame-retardant and anti-static material. The surface resistance is ≤3×10^8Ω, meeting mining explosion-proof safety requirements. It also has an IP67 protection rating, resisting dust and mud intrusion, and is suitable for a wide temperature range of -40℃ to 120℃, with a service life of over 8 years under harsh outdoor conditions. Featuring an M16×1.5 standard threaded interface and an M12x1 waterproof plug design, it strictly matches the original XCMG brake line installation dimensions, allowing for quick integration without additional modifications. The wiring is simple and the contact resistance is ≤0.1Ω, ensuring stable signal transmission, significantly reducing maintenance costs and failure risks, and meeting the high reliability and safety standards of XCMG accessories.

Application Scenarios

Suitable for the XCMG GR2605 grader in driving, working, and emergency braking conditions in mining, open-pit mining, road construction, and large-scale infrastructure projects. Especially suitable for the harsh mining environment with high-frequency braking, severe vibration, and flammable and explosive materials. As the “safety signal center” of the braking system, its high-precision pressure detection and rapid signal response capabilities ensure that the brake lights and braking actions are triggered synchronously, providing clear safety warnings to following vehicles and construction personnel, effectively avoiding collisions. Simultaneously, it provides real-time feedback on the braking system pressure status; when the pressure is abnormal, it can link with the vehicle control system to issue a warning, preventing the risk of brake failure and significantly improving the overall driving and operating safety of the machine. It is an original factory-grade safety adapter part for the XCMG GR2605 grader braking system repair and replacement.
