Solenoid Valve
Structurally, the solenoid valve in Komatsu construction machinery components consists of an electromagnetic part and a valve body part. The electromagnetic part is composed of coils, iron cores, fixed components, etc., and is the core component of the solenoid valve, mainly playing the role of switching circuits. The valve body is composed of valve sleeve, valve core, spring, sealing gasket, etc. It is the working link of the solenoid valve, mainly controlling the flow direction and pressure of the fluid.


Relay
Relays in Komatsu construction machinery accessories are widely used in various types of construction machinery, such as excavators, loaders, rollers, bulldozers, etc. They can be used to control various functions in mechanical operating systems, such as acceleration, deceleration, smoke exhaust, fuel injection, etc. In construction machinery, the role of relays is crucial, and their accuracy and reliability directly affect the efficiency and safety of mechanical equipment.
Switch
The switches in Komatsu construction machinery accessories can be classified into many types according to their different functions and purposes, such as control switches, limit switches, safety switches, power switches, and so on. Among them, control switches are the most common type of switches used to control the operation and manipulation of Komatsu construction machinery, making the work of the machinery more precise and efficient.


Sensor
There are many types of sensors in Komatsu construction machinery accessories, including wheel speed sensors, oil pressure sensors, liquid level sensors, temperature sensors, and so on. These sensors can monitor various physical quantities generated by mechanical motion, providing them to the machine control system for analysis and judgment, making the machine work more stable and efficient.
Monitor
The monitor of Komatsu Construction Machinery have multiple advantages. Firstly, they are sturdy and durable, and can adapt to various environments and complex work scenarios; Secondly, their monitor effect is very good, using international advanced technology to clearly reflect various indicators of mechanical operation, providing accurate information and data for operators; Finally, the monitor of Komatsu Construction Machinery also has the characteristic of intelligence, which can automatically monitor the operation status of the equipment, provide warning information, and facilitate the maintenance and upkeep of the equipment.


Harness
A wiring harness is a device that bundles several wires, cables, and connectors together to form a whole. In Komatsu construction machinery, wiring harnesses play an important role in transmitting signals, currents, and other information between electronic devices. Wiring harnesses have the characteristics of flexibility, convenience, safety, and aesthetics, which can effectively reduce safety hazards caused by loose or scattered wires.
