The 81.27421.0129 (81274210129) 4-pin speedometer pulse sensor is a high-precision transmission output electronic sensor engineered for Shacman Delong F3000 heavy commercial trucks. Installed on the transmission output shaft housing, it detects shaft rotation speed and converts it into precise electrical pulse signals sent directly to the vehicle ECU and dashboard instrument cluster.
The 81.27421.0129 4-Pin Speedometer Odometer Sensor plays a critical role in heavy commercial vehicle electrical and driver information systems. By accurately reading transmission output shaft speeds, this Shacman F3000 speed sensor provides essential pulse data needed to display real-time road speed on the speedometer, calculate total mileage on the odometer, and support tachograph speed logging.
Manufactured in ISO9001-certified facilities using high-sensitivity magnetic-induction components housed in durable, corrosion-resistant casing, the 81.27421.0129 sensor is built to withstand high transmission oil temperatures and severe chassis vibration. Replacing a erratic, non-responsive, or oil-soaked sensor with a 100% factory-tested 81.27421.0129 unit restores accurate speedometer function, eliminates speed-signal ECU error codes, and ensures fleet tachograph compliance.
