YT552Y-50 RPM Sensor (P/N 803681578)
Original equipment speed sensor for XCMG construction machinery platforms. φ50 sensing head, M50 mount, engineered for crankshaft / gearbox / wheel-end speed pickup in demanding jobsite conditions.
Speed / RPM Sensor YT552Y-50 (XCMG OEM No. 803681578) is rotational speed pickup specified for XCMG construction machinery powertrain systems. φ50 sensing head with M50 threaded mount ("-50" suffix), designed for crankshaft, gearbox output, or wheel-end speed acquisition. Loss of RPM signal typically forces limp-mode or no-start on diesel equipment—making this a high-priority downtime-spare.
YT prefix (same family: YT552D, YT366DFA-ZL) appears across XCMG + Zoomlion sensor BOMs (e.g., XCMG GR165 motor grader, QY50K crane), confirming OEM-tier supply status.
