Electrical Parts for Hydraulic and Mobile Machinery Systems
Electrical parts for hydraulic systems are essential components used to control, activate and monitor hydraulic functions in construction machinery, mobile equipment and industrial systems.
HPM Hydraulic supplies coils, switches and control devices for hydraulic and electro-hydraulic applications. These components can be used with hydraulic valves, pumps, motors, control blocks and other machine systems.
Types of Electrical Parts Available
Hydraulic Solenoid Coils
Hydraulic solenoid coils generate a magnetic field when electrical current is applied. This magnetic force operates the armature of a solenoid valve and allows hydraulic flow or pressure to be controlled electrically.
Switches
Electrical and hydraulic switches are used to detect pressure, position or operating conditions and send a signal to the machine control system.
Control Devices
Control devices include electrical and electro-hydraulic components used to manage machine functions, valve operation and hydraulic system control.
Electrical Components in Hydraulic Systems
Modern hydraulic systems often combine hydraulic power with electrical control. Electrical components can be responsible for:
- activating hydraulic valves,
- switching hydraulic functions on or off,
- monitoring pressure or position,
- sending feedback to controllers,
- controlling proportional hydraulic functions,
- protecting machinery against incorrect operating conditions.
How to Select the Correct Electrical Part
Electrical components should be selected according to both mechanical compatibility and electrical specification.
Check:
- OEM or manufacturer reference,
- component model,
- rated voltage,
- current or power rating where applicable,
- connector type,
- mounting dimensions,
- machine make and model,
- hydraulic valve or system compatibility.
Voltage
The electrical voltage must match the machine system. Common mobile hydraulic systems may use different supply voltages depending on the equipment design.
Installing a component with an incorrect voltage can cause malfunction or permanent electrical damage.
Connector Type
Electrical connectors can differ by shape, pin arrangement and sealing design. Always compare the connector with the original component before installation.
OEM Number and Reference
The OEM number or complete manufacturer reference is usually the safest way to identify a compatible electrical component. Similar-looking coils, switches or controllers may have different electrical characteristics.
Common Symptoms of Electrical Component Failure
- hydraulic valve not responding,
- intermittent hydraulic operation,
- machine fault codes,
- overheating of a solenoid coil,
- incorrect sensor or switch signal,
- hydraulic function operating only occasionally,
- damaged connectors or wiring.
Before replacing an electrical component, check wiring, connectors, supply voltage, ground connection and the hydraulic component controlled by the electrical part.
Replacement Electrical Parts from HPM Hydraulic
HPM Hydraulic supplies replacement electrical parts for hydraulic systems and construction machinery. Components can be identified by OEM number, manufacturer reference, electrical specification and machine application.
If you are unsure which part is required, provide the complete reference number, machine model and photographs of the original component.

FAQ – Electrical Parts for Hydraulic Systems
What electrical components are used in hydraulic systems?
Common components include solenoid coils, switches, sensors and control devices used to operate or monitor hydraulic functions.
Why is the voltage important when selecting a hydraulic coil?
The coil must match the electrical supply of the machine. Incorrect voltage can prevent proper operation or damage the coil.
Can two identical-looking electrical parts have different specifications?
Yes. Voltage, resistance, connector type, control signal and internal construction may differ.
How do I identify the correct replacement?
Use the OEM number, manufacturer reference, voltage, connector type and machine model.
