Pre-inspected components specialized for commercial integration in Victoria's audio and electro-mechanical manufacturing hubs.
As Australia's technology and advanced design capital, Melbourne sustains a highly sophisticated electronics industry sector spanning biomedical devices, public communication infrastructure, and professional audio system engineering.
From the biomedical tech corridor in Parkville to the design labs of Melbourne's Monash and Tullamarine enterprise hubs, product designers require components that meet rigorous durability and precision benchmarks. The demand for 3.5mm headphone jacks (TRS and TRRS configurations) has expanded beyond consumer audio. Today, these interface sockets act as crucial data-transmission channels, sensor ports in scientific instruments, and backup communication hookups in public transit networks like Metro Trains Melbourne.
Melbourne’s local climate—characterized by sudden temperature fluctuations and high humidity periods—means industrial electronic components must withstand galvanic corrosion and thermal expansion. Our components utilize high-grade phosphor bronze alloys and high-temperature thermoplastic resins (LCP/PA9T) to prevent contact failure and housing deformation during automated reflow soldering processes up to 260°C.
Founded in 2005, we have dedicated two decades to mastering the research, engineering, and manufacturing of premium interconnect solutions.

For St. Peter, quality is always precious, guided by technology and based on safety. From the initial selection of raw materials for the product, to the production line processing, and finally to the inspection and testing process—every step is meticulous, providing a solid foundation and quality assurance for the product.
Our facilities are fully outfitted to manufacture a wide variety of parts including IF Radio-Frequency Terminals, FCB Network Jacks, DC Power Outlets, USB Sockets, AV Pin Jack Boards, and Radiators. With high-level punching machines, advanced CNC lathes, and automatic multi-stage optical inspection rigs, we maintain a production precision limit within ±0.01mm.
Retaining complete original project inventories for specialized commercial applications and custom interface setups.
Streamlined lead times, regulatory alignments, and technical customization under the China-Australia Free Trade Agreement (ChAFTA).
Our manufacturing facility in Wenzhou enjoys direct proximity to the deep-water shipping lanes of Ningbo-ZH port and Shanghai Port. This enables rapid consolidated ocean freight direct to the Port of Melbourne within 18–25 days. For prototype design iterations, our proximity to Wenzhou Longwan International Airport guarantees express air courier shipments (via DHL/FedEx) arriving in Victoria within 3 to 5 business days.
Our 3.5mm audio jacks leverage advanced engineering plastics like Liquid Crystal Polymer (LCP) to resist structural warpage during automated assembly. Contact terminals are stamped from C5191 phosphor bronze, coated with a nickel underplate and finalized with a high-durability gold flash or thick gold plating (up to 15u"). This configuration ensures less than 30mΩ contact resistance and guarantees over 5,000 insertion cycles, ideal for high-use public kiosks and specialized medical sensors in Australia.
Over 30 technical R&D personnel driving innovation with an annual investment exceeding 15 million Yuan. Holding 21+ active research and development patents to ensure unique design advantages.
Rigorous raw material selection, advanced in-line optical sorting, automated insertion force validation, and high-frequency noise testing safeguard every production batch from factory seconds.
Leveraging fully automated high-speed insert molding, precise continuous stamping, and robotic assembly stations to scale production while maintaining tight dimensional tolerances.
Industry-standard 3.5mm audio and electromechanical interconnects engineered to withstand high-volume assembly lines.
Our technical expertise is driven by an aligned, collaborative, and highly motivated workforce.
In this summer, our company organized an outdoor team-building activity to strengthen cohesion and foster teamwork. The event took place in a picturesque natural setting, providing a perfect backdrop for enhancing team spirit and collaboration.
The team-building activity was designed to promote unity and cooperation among the employees. Through a series of challenging and fun exercises, the participants had the opportunity to work together, communicate effectively, and problem-solve as a team. It was a great chance for everyone to bond, both personally and professionally, outside the confines of the office environment.
One of the highlights of the day was a series of team-based challenges that required trust, coordination, and quick thinking. These activities encouraged individuals to step out of their comfort zones, build trust in their colleagues, and see the value of working together towards a common goal. As a result, the event not only improved teamwork but also boosted morale and motivation within the company.
Furthermore, the outdoor setting provided a refreshing change of scenery, allowing everyone to unwind and connect with nature. This change of environment helped in reducing work-related stress and promoting a sense of well-being among the participants. It was a great opportunity for the team to relax, recharge, and return to work with renewed energy and enthusiasm.
Essential insights for engineering leads, procurement managers, and hardware designers in Australia.
We use high-grade phosphor bronze alloys (C5191) for the internal spring contacts to guarantee fatigue resistance and consistent contact pressure. The plastic housings are molded from Liquid Crystal Polymer (LCP) or high-temperature PA9T, enabling them to survive SMT reflow profiles up to 260°C without mechanical distortion or pin displacement.
All our products are fully compliant with RoHS and REACH regulations, preventing the ingress of hazardous heavy metals into Victoria's supply chain. In addition, we conform to ISO 9001:2015 QC processes and provide safety certifications such as CE, which directly support your RCM (Regulatory Compliance Mark) approvals within Australia.
Standard ocean freight shipments from Wenzhou via Ningbo or Shanghai Port to the Port of Melbourne take approximately 18 to 25 days. For express engineering prototypes or urgent production runs, air cargo options can deliver parts to Melbourne (Tullamarine) within 3 to 5 business days.
Yes. Backed by our dedicated team of 30+ R&D professionals and an annual R&D investment of 15 million Yuan, we offer comprehensive OEM/ODM customization services. We can customize contact shapes, add grounding shielding plates, change SMT layout pins, or modify plastic housing colors to match your assembly line parameters.
We conduct 100% automated optical inspections (AOI) to confirm correct dimensions and pin alignment. Furthermore, our laboratories execute mechanical lifetime tests (up to 5,000 cycles), dielectric strength tests, insulation resistance checks (≥100MΩ at 500V DC), and solderability checks to guarantee zero failures upon delivery.
