New Pressure Differential Sensor EX200-3 EX200-5 4339559 | Hitachi Excavator Sensor

Description

This brand-new pressure differential sensor with OEM part number 4339559 is a critical monitoring component for Hitachi EX200-3 and EX200-5 excavators. The sensor continuously measures the pressure difference across the hydraulic oil filter, alerting the machine’s control system when filter restriction exceeds safe thresholds. This early warning capability prevents catastrophic hydraulic system failures by prompting timely filter replacement before contaminants reach sensitive pump and motor components. The 4339559 sensor features a robust housing compatible with Hitachi’s original mounting configuration and electrical connectors. It operates across a pressure range of 0 to 0.6 MPa with high accuracy signal output. Compatible with both EX200-3 and EX200-5 models. The new-condition sensor provides reliable readings from day one, unlike used or rebuilt units. Installation requires no special tools — direct bolt-on and plug-in replacement. Essential for preventive maintenance programs on Hitachi EX200 excavator fleets. Available for immediate shipping worldwide with full compatibility guarantee.
