DUOYUAN
Modular RJ connectors, PCB jacks and telecommunications components
About the manufacturer
Zhejiang Duoyuan Electronics is a Chinese manufacturer of connectors used primarily in telecommunications, networking equipment and consumer electronics. Established in the late 1990s, the company develops modular jacks and plugs, PCB-mounted connectors and interface components for communications equipment.
The product portfolio focuses on widely used RJ11, RJ12 and RJ45 standards as well as shielded jacks, versions with LEDs and connectors integrating filtering elements. This allows Duoyuan components to be used in products ranging from telephone equipment to network devices and industrial electronics.
Duoyuan offers through-hole and PCB-oriented designs. Important selection parameters include the mechanical format, pin arrangement, cable-entry direction, number of contacts, shielding and contact plating.
The manufacturer addresses OEM projects that require standard communication interfaces in multiple mechanical variants and configurations.
Applications
Duoyuan connectors are used wherever equipment needs a standard compact interface for signal or data transmission. Typical applications include:
- Telecommunications – telephones, exchanges and subscriber equipment.
- Computer networks – Ethernet interfaces and communication devices.
- Routers and modems – connectors for wired links.
- Industrial automation – communication ports in controllers and terminals.
- Consumer electronics – products equipped with modular RJ interfaces.
- Measurement equipment – service and communication connectors.
- OEM systems – integration of standard interfaces on PCBs.
