Harness Master Wiring Systems

At HMWS, we design overmolded cable assemblies built for tough environments.

Each unit is fully sealed, with the cable, connector and housing fused into one IP-rated structure.

By eliminating mechanical joins, overmolding eliminates common failure points and creates a seamless barrier against water, chemicals, vibration, and wear.

If your current setup relies on frequent maintenance or field terminations, it might be time to upgrade to a more reliable solution.

At HMWS, IP ratings aren’t just a technical detail, they’re a guide to building products that last in real-world conditions.

In industrial environments, dust, moisture, water, and debris can quickly impact performance if components aren’t properly protected, leading to more maintenance, downtime, and reduced lifespan.

That’s why our wiring systems, connectors, and assemblies are designed with the right level of ingress protection in mind, ensuring reliable performance where it matters most.

If you’re unsure what protection level you need, our team is here to help.

The M10 Feed Through Terminal Stud provides a secure and efficient power connection solution with an IP67 rated design.

Each stud is easily identified with brass components and a durable nickel plated finish, each clearly identified with red and black colouring for fast and accurate use of the positive and negative connections.

Designed with practicality in mind, the compact unit enables a smooth installation process without the need for specialised tools, helping reduce downtime while delivering long lasting reliability across a variety of applications.

Our service team delivers a seamless end-to-end experience, supporting clients from project delivery through to ongoing aftercare.

Beyond installation, we provide responsive support, maintenance assistance, and ongoing guidance to ensure long-term performance and confidence.

As demand for reliable infrastructure grows, our focus remains on consistency, quality, and building lasting client partnerships well beyond completion.

There is no better measure of what we do than what our customers say about us.

Our partnership with Ausplow reflects the values HMWS was built on. Reliable delivery, transparent communication, competitive pricing and a service that adapts to the needs of the customer.

When something is urgent, we work to make it happen. When there is a challenge, we communicate early and find a solution together. That is what a genuine partnership looks like.

We are proud to work alongside businesses like Ausplow and look forward to continuing to support them.

Small electrical faults can quickly turn into big, costly problems.

With today’s increasingly complex vehicle systems, protecting your wiring from the start is essential. The right components can help prevent damage, reduce downtime, and keep everything running reliably.

The HMWS ISO 280 Series 6 Amp Diode is designed to do exactly that by supporting better performance and long-term system protection.

Treating overmolding as an afterthought is where many organisations fall short. At HMWS, it’s a core part of every project stage.

By managing overmolding in-house, we reduce supplier handoffs, streamline design-to-production, and deliver:
↳ Faster DFM cycles with real-time prototyping feedback
↳ Greater material and dimensional traceability
↳ Secure private label manufacturing
↳ Scalable production without outsourced tooling delays

The result is cleaner cable assemblies, fewer connector failure points, and a more reliable supply chain.

When reliability matters, the HMWS ISO 280 Series 6 Amp Diode delivers.

Built for tough environments, its sealed design helps protect wiring components from dust and moisture, keeping performance consistent where it counts.

With flexible custom options to suit your setup, it’s a practical solution for a wide range of demanding applications.

Quality comes standard at HMWS. Durability, efficiency and compliance are built into everything we manufacture.

To keep standards high, we carry out mid-process inspections to monitor performance and catch issues early.

The result is more consistent products, fewer defects and less rework.
It is all part of making sure our customers get reliable, high-quality products every time they work with us.

In environments where downtime, water ingress, and cable failures can halt operations instantly, every connection matters.

HMWS delivers tailored solutions built for performance through high-quality overmolded assemblies, custom metal fabrication, true plug-and-play integration and tooling, we help keep operations moving when it matters most.

Supporting the underground rock industry allows us to develop and hone our expertise to create the most efficient solutions and effective outcomes.

This is carried on after production through our aftermarket support where we assist in reordering parts, assist in servicing and fault finding, and hold stock to support maintenance activities.
