Product Core Information (Model: 418-43-37681)

 (Model: 418-43-37681)

This is mainly adapted to Komatsu loaders and other construction machinery.

Precise Pressure Triggering

Operating pressure: 0.29 MPa, reset pressure: 0.24 MPa. The fixed pressure difference design ensures stable signal output and avoids frequent false triggering.

Proof pressure: 1.47 MPa, capable of withstanding instantaneous pressure fluctuations in the system to ensure safety.

Reliable Structural Design

Copper threaded interface for excellent sealing performance, corrosion resistance and oil resistance.

Integrated wiring harness plug with waterproof design, easy to install and suitable for complex wiring environments of construction machinery.

Internal elastic element + microswitch structure, fast response speed, and mechanical life of over one million cycles.

Brand Quality Assurance

Originated from NAGANO KEIKI (Japan), with industrial-grade accuracy and stability, meeting the harsh working conditions of construction machinery.

Integrity-based, customer-oriented, quality-winning.

Product Advantages

High Reliability: Vibration and shock resistant design, ensuring stable operation in bumpy and dusty construction machinery environments, reducing downtime due to failures.

Easy Installation & Maintenance: Standard threaded interface + plug-and-play wiring harness, no complex modification required, convenient to replace original parts.

Precise Control: Fixed pressure difference design ensures consistent pressure signal output, improving equipment control accuracy and safety.

Strong Adaptability: Specially designed for the transmission/hydraulic systems of Komatsu loaders (such as WA380-6, WA470-6, etc.), compatible with original electrical protocols.

Application Areas

Core Construction Machinery Scenarios

Mainly used in the transmission hydraulic systems of Komatsu loaders (WA380-6, WA470-6, etc.) to monitor oil pressure and output signals for shift control and overload protection.

Can be extended to hydraulic circuits of excavators, motor graders and other equipment for pressure monitoring and safety interlocking.

Industrial Hydraulic/Pneumatic Systems

Suitable for hydraulic stations, air compressors, injection molding machines and other equipment, as a key component for overpressure alarm and pump start/stop control.

Equipment Safety Protection

Acts as a "safety sentinel" in hydraulic/pneumatic circuits, triggering circuit on/off when pressure is abnormal to prevent pipeline burst and component damage.
