7861‑93‑1811 High‑Pressure Sensor 500Bar for Komatsu PC200‑8 PC220‑8 Excavator

7861‑93‑1811 Komatsu 500‑Bar high‑pressure sensor fits PC200‑8, PC210‑8, PC220‑8 excavators. It sends hydraulic‑pressure data to ECU to fix engine‑lugging issues with imported core, OEM plug‑and‑play and factory‑calibration.

Product Name

Komatsu Excavator High‑Pressure Sensor

Part No.:7861‑93‑1811, Measuring Range:50MPa(500Bar)

Applicable Models

Fit for Komatsu Excavator PC200‑8, PC210‑8, PC220‑8, PC240‑8, installed on main hydraulic pump and control valve.

Technical Parameters

Measuring Range:0‑50MPa (500Bar). Integrated‑design with built‑in O‑ring seal and OEM 4‑pin plug‑and‑play connector;
Function: It collects real‑time high‑pressure data of hydraulic main circuit and transmits signals to excavator ECU to adjust pump output. Defective sensor causes weak operation, slow movement, engine‑lugging and hydraulic fault codes.

Product Advantages

Imported high‑precision sensor core withstands high‑pressure impact, hydraulic‑oil corrosion and continuous vibration on construction‑site;
Sturdy stainless‑steel thread and anti‑aging sealing‑ring prevent oil‑leakage; anti‑oxidation 4‑pin terminals avoid poor‑contact with direct‑fit installation;
OEM original and aftermarket replacement versions available. Every unit passes pressure‑calibration test before delivery with 3‑12‑month warranty.

Installation Notes

Release residual hydraulic‑system pressure and clean dirt on thread before installation;
Tighten with standard torque to avoid thread damage, keep connector firmly plugged and waterproof;
Clear fault codes after installation and test‑run the excavator.
