Key Features
Exact Direct Fit: Matches Hitachi original specifications for seamless plug-and-play installation on ZX-series excavators. No adapters, programming, or modifications required.
RPM & Speed Monitoring: Designed for engine crankshaft speed detection, camshaft position sensing, hydraulic pump speed monitoring, and swing motor rotation measurement.
Precision Sensing: Delivers accurate real-time speed data to the Hitachi ECU, enabling proper engine governing, fuel injection timing, pump flow control, and system synchronization.
Robust Construction: Built with high-grade magnetic or hall-effect sensing elements, sealed housings, IP67-rated protection, and OEM-spec Hitachi/Yazaki/Sumitomo/Deutsch connectors for extreme job site durability.
Failure Prevention: Replaces faulty revolution sensors to eliminate engine overspeed/underspeed, poor acceleration, erratic idle, weak hydraulic response, active diagnostic trouble codes, and machine shutdowns.
