RJ45/RJ11 electrical connectors serve as physical interfaces for Ethernet and telephone systems. MTCONN's Cat6A RJ45 jacks comply with the 10GBase-T standard and feature an eight-wire independent shielding design, while the PoE++ version supports 60W power delivery. These connectors are widely used in network equipment such as IP cameras and industrial switches.

Registered Jack Connectors for High-Performance Network & Telecom Systems

Registered Jack connectors (RJ45 / RJ11) are essential physical interfaces for Ethernet and telecommunication systems, enabling stable data transmission and reliable power delivery across modern networks. Designed for commercial, industrial, and infrastructure-level deployments, our connectors are widely adopted in projects where performance consistency, long-term reliability, and large-volume supply capability are critical.

Cat6A RJ45 Jacks for 10G Ethernet Applications

M&T Cat6A RJ45 jacks are engineered to meet 10GBase-T transmission requirements, supporting high-speed data transfer over structured cabling systems. The eight-wire independent shielding architecture effectively reduces crosstalk and electromagnetic interference, ensuring signal integrity even in dense or high-noise environments.

These connectors are ideal for applications such as:

• Enterprise and data center networks

• Industrial Ethernet systems

• IP surveillance and security infrastructure

• Managed and unmanaged network switches

For projects requiring both data and power transmission, the PoE++ RJ45 jack version supports up to 60W power delivery, making it suitable for high-power devices without compromising network stability.

RJ45, RJ11 & RJ12 Modular Jack Solutions

Different Registered Jack interfaces serve different data and telecommunications requirements. M&T offers multiple RJ Modular Jack configurations so engineering and purchasing teams can match the connector to the interface, PCB, enclosure, and end equipment.

RJ45 Connectors for Ethernet Networking

M&T RJ45 Connectors include 8P8C and other configurations designed for Ethernet and network equipment. Available product structures include shielded RJ45 jacks, PCB-mounted connectors, LED-equipped models, and combination interfaces.

For higher-speed networking projects, selected Cat6A RJ45 Jacks are designed for 10GBase-T applications. Shielding structures help control electromagnetic interference and crosstalk in electrically noisy or high-density network environments.

Typical applications include:

• Industrial Ethernet equipment

• Network switches and routers

• IP cameras and surveillance systems

• Communication equipment

• Smart building controllers

• Embedded network devices

RJ11 & RJ12 Connectors for Telecom Interfaces

M&T also supplies RJ11 and RJ12 Connectors, including 6P6C female connector configurations for telecommunications and related signal interfaces.

These modular jacks can be integrated into communication terminals, telephone-related equipment, control systems, security devices, and other products requiring compact modular interfaces.

Cat6A, 10GBase-T & PoE RJ45 Connectivity

For network equipment manufacturers, connector selection increasingly involves both data bandwidth and power delivery.

Selected M&T Cat6A RJ45 Connectors support 10GBase-T Ethernet requirements for high-speed network applications. Independent shielding structures help improve signal integrity by reducing interference between transmission channels and limiting external EMI effects.

For devices requiring power through the Ethernet connection, selected PoE++ RJ45 Connector configurations support power delivery up to 60W. This allows compatible equipment to transmit data and receive power through the same network interface, reducing separate power wiring in applications such as IP cameras, network devices, and industrial Ethernet equipment.

Actual transmission, shielding, and PoE specifications vary by connector model. Buyers should confirm the required Ethernet category, power level, and equipment design before product selection.

Shielded, LED & PCB Mount RJ45 Connector Options

RJ connector selection is not limited to RJ45 or RJ11 interface type. The physical configuration of the connector also affects PCB layout, EMI performance, equipment status indication, and final assembly.

M&T offers different options according to the connector series.

Shielded RJ45 Connectors

Shielded RJ45 Jacks use a metallic shielding structure to help reduce electromagnetic interference. They are particularly relevant to industrial Ethernet, communication, surveillance, and other applications where signal integrity is important.

RJ45 Connectors with LED

Selected RJ45 models integrate indicator LEDs, allowing equipment designers to provide network connection or activity status directly at the interface.

PCB-Mounted Modular Jacks

M&T provides RJ modular jacks designed for direct PCB integration, including right-angle DIP configurations. Connector orientation, PCB footprint, terminal arrangement, and housing dimensions should be matched to the equipment layout.

RJ45 + USB Combination Connectors

For equipment requiring multiple external interfaces in limited panel space, M&T also offers RJ45 + USB combination connectors. Integrating network and USB interfaces into one connector assembly can simplify panel design and reduce PCB interface footprint.

How to Select an RJ45 or RJ11 Connector

For OEM projects, choosing the correct RJ Connector requires matching network performance with the PCB and mechanical design of the equipment.

Important selection factors include:

• Interface Type – RJ45, RJ11, RJ12, or a combined interface according to equipment requirements.

• Contact Configuration – Confirm configurations such as 8P8C or 6P6C.

• Network Performance – Determine the required Ethernet category and transmission speed.

• PoE Requirement – Check whether the equipment requires data only or simultaneous data and power transmission.

• Shielding – Select shielded or unshielded construction according to EMI conditions and system requirements.

• LED Configuration – Determine whether integrated network status indicators are required.

• PCB Mounting & Orientation – Match the connector footprint and mating direction to PCB and enclosure design.

• Port Configuration – Consider interface quantity and available equipment panel space.

• Mechanical Durability – Evaluate mating frequency and long-term interface reliability.

• Operating Environment – Temperature, electrical noise, vibration, and other conditions should be considered for industrial applications.

Providing a PCB drawing, existing connector part number, sample, or detailed interface requirements helps M&T identify a suitable connector more efficiently.
