Collection: Electrical Parts

Why Electrical Parts Are the Foundation of Your Excavator's Performance

Modern excavators and construction equipment are precision machines, and their electrical systems are what make that precision possible. Every dig cycle, every hydraulic movement, and every operator input flows through a network of heavy machinery electrical parts working in real time.

Here is what your excavator's electrical system is doing every minute it is running:

  • Routing power through the machine: wiring harnesses distribute electrical supply to every system from the engine bay to the cab
  • Monitoring critical conditions: sensors track engine speed, coolant temperature, hydraulic pressure, fluid levels, and attachment position continuously
  • Controlling hydraulic flow: Solenoid valves translate electrical signals into precise hydraulic movements, which the machine acts on
  • Processing machine intelligence: control units and ECUs receive sensor data and operator inputs to manage and protect machine performance
  • Displaying real-time machine data: monitors and instrument clusters give operators live visibility of operating conditions and fault alerts
  • Receiving operator commands: switches, joysticks, and controls convert every operator action into a machine response

A failure in any of these components disrupts that chain. The faster the failed part is replaced with a quality-matched alternative, the shorter your downtime and the lower your repair cost. That is exactly what Imara Engineering is here for.

Our Full Range of Excavator Electrical Parts and Heavy Equipment Electrical Components

Imara Engineering organises its catalogue into six dedicated electrical parts sub-categories, each stocked with OEM-matched aftermarket parts verified against the brands and models your fleet operates. Navigate directly to the category your machine needs:

Wiring Harnesses

Wiring harnesses are the electrical backbone of your excavator, bundled cable assemblies that route power and data signals to every system on the machine. A damaged harness causes widespread and difficult-to-diagnose electrical faults across multiple systems simultaneously. Our wiring harness range covers excavator, engine, and chassis harnesses for CAT, Komatsu, Hitachi, and Cummins platforms, including C15, C15 ACERT, and 3406E engines.

Sensors

Sensors are the intelligence layer of your excavator's electrical system, monitoring engine speed, hydraulic pressure, coolant temperature, fluid levels, and attachment position to feed accurate data to your control unit in real time. Without accurate sensor signals, your machine cannot protect itself or perform with precision. Imara Engineering stocks a full range of heavy machinery sensors across five dedicated categories: speed sensors, temperature sensors, pressure sensors, position sensors, and level sensors.

Solenoid Valves

Solenoid valves are the electromechanical bridge between your excavator's electrical control signals and its hydraulic systems. When energised, the electromagnetic coil moves a plunger to open or close fluid passages, directing hydraulic flow with precision for every digging, lifting, and travel function. Our range covers 12V and 24V hydraulic solenoid valves, proportional valves, and directional solenoid valves compatible with CAT, Komatsu, Hitachi, Kobelco, Bosch Rexroth, and Danfoss systems.

Control Units and ECUs

Control units and ECUs are the brain of your excavator, electronic modules that process incoming sensor data, regulate engine performance, manage hydraulic output, and execute every operator command. A failed ECU or machine controller can render the entire machine inoperable. Our range covers excavator ECUs, pump controllers, computer box replacements, and machine controllers for CAT, Komatsu, Hitachi, Volvo, and Bobcat platforms.

Display Monitors

Excavator display monitors and instrument clusters give operators real-time visibility of machine health: engine temperature, fuel levels, hydraulic pressure, fault codes, and operating hours all read from a single display. A failed monitor leaves your operator blind to critical machine conditions while the machine continues to run. Our range covers LCDs, gauge clusters, instrument panels, and dashboard monitors for CAT, Komatsu, Hitachi, and other leading OEM brands.

Switches and Controls

Switches and controls are the operator interface of your excavator, the joysticks, ignition switches, toggle switches, and control assemblies that translate every operator input into machine action. Worn or failed controls cause loss of machine function and can compromise operator safety on site. Our range covers excavator joysticks, ignition switches, operator control assemblies, and toggle switches compatible with CAT, Komatsu, Hitachi, Kobelco, and Takeuchi equipment.

OEM-Quality Aftermarket: Is It Acceptable for Heavy Machinery Electrical Parts?

This is the question every plant manager, fleet supervisor, and workshop technician asks before sourcing construction equipment electrical parts from an aftermarket supplier. The answer, when you are buying from a specialist like Imara Engineering, is unambiguously yes. Here is what OEM-quality means in practice at Imara:

  1. Manufactured to original specifications: connector type, pin configuration, voltage rating, signal output, and dimensional fitment are all matched to the OEM part.
  2. Cross-referenced before listing: every part in our catalogue is verified against original manufacturer part numbers before it is published, so if it is listed, fitment is confirmed.
  3. Not a generic approximation: we stock precision-matched excavator electrical components, not parts that approximately fit.
  4. Built to perform from day one: our parts are not trial-and-error replacements; they are designed to work exactly as the original did, immediately on installation.

OEM-quality aftermarket means the same performance, confirmed fitment, and a price point that makes operational and commercial sense for your business.

Brand Compatibility: Electrical Parts for the Machines You Operate

Our heavy equipment electrical parts range is built around the brands that dominate construction and mining job sites across Australia, North America, and internationally.

Caterpillar (CAT): Cat electrical parts, including wiring harnesses, sensors, solenoid valves, ECUs, monitors, and switches across the CAT excavator and engine range.

Komatsu: Komatsu electrical parts, including sensors, solenoid valves, ECUs, monitors, and switches for PC-series and WA-series equipment.

Hitachi: Hitachi electrical parts, including sensors, solenoid valves, ECUs, monitors, and switches for the ZX and EX excavator series.

Cummins: Wiring harnesses, engine speed sensors, and engine electrical components for ISX, X15, N14, ISB, and ISC platforms.

Kobelco: Solenoid valves, pressure sensors, position sensors, and joystick controls for SK-series excavators.

Bobcat: ECUs and electronic control modules for Bobcat compact equipment.

Volvo: ECUs and machine control units for Volvo excavator platforms.

Cannot find your brand or model in the list above? Contact the Imara Engineering parts team directly. We regularly source caterpillar electrical parts and components for less common makes, older machines, and equipment that OEM dealers no longer actively support.

Fast Dispatch to Australia, USA, Canada, and International Destinations

At Imara Engineering, speed of dispatch is built into how we operate, not something bolted on as an afterthought. Downtime is your most expensive operating cost, and every hour your machine waits for a part is a direct cost to your business.

  • Orders are processed and dispatched promptly after confirmation.
  • Full shipment tracking is provided on every order.
  • We ship heavy equipment and electrical parts to Australia, the United States, Canada, and internationally.
  • Single replacement parts and bulk workshop stock orders are handled with the same priority.

No extended dealer lead times. No back-order delays. Your excavator electrical parts are moving toward your site from the moment the order is placed.
