ATEN RJ-45 (J-45) Male Wire Connector 2A-245G, Silver, for Cat6A cabling

The ATEN RJ-45 (J-45) Male Wire Connector 2A-245G is a silver, shielded Cat6A-compatible crystal head designed to terminate Ethernet cables and establish reliable network links. The one-piece die-cast RJ-45 body with reinstallable metal shielding provides stable transmission, supports data rates exceeding 10 Gbps, and meets FCC Part 68 requirements. The connector is compatible with PoE/POH and fits a range of solid or stranded cable types, with particular recommendation for use with 2L-29330 Cat6A cables. It includes an IP20 dust cover and meets RoHS/REACH material standards.

Advantages

Metal shielding and a die-cast construction reduce electromagnetic crosstalk and external interference, contributing to consistent high-speed data transfer and long-term durability. The connector is designed for tool-less, colour-coded installation and is reinstallable for reuse without degrading performance. A screw-on metal strain relief boot prevents excessive bending and improves EMI protection, while compatibility with 22–26 AWG cables and over 750 mating cycles makes it versatile for various network setups.

Suitable for

• Termination of Cat6A Ethernet cables in patch panels and network outlets
• On-site cable assembly and field repairs for professional installers
• DIY cable assembly for home or small office networks using Cat6A or compatible solid/stranded cables

When it may not be suitable

This connector is intended for Cat6A and compatible higher-performance cabling; it may not be necessary for legacy Cat5e installations where full Cat6A performance is not required. It is a single RJ-45 plug and does not replace modular jacks, couplers, or pre-terminated patch cords; use those products when a different form factor is needed.

Key specifications

• Compatibility: Cat6A (recommended), suitable for Cat6A–Cat8 solid or stranded cables
• Data rate: supports over 10 Gbps
• Contact life: jack insertion life > 750 mating cycles
• Cable gauge: 22–26 AWG
• Shielding: metal shielded crystal head with screw-on metal strain relief boot
• Standards: FCC Part 68 compliant; RoHS and REACH material compliance
• Ingress protection: includes IP20 dust cover
• Connector colour and material: silver zinc die-cast body

How to use

Strip the cable jacket and arrange pairs according to the chosen wiring standard. Insert wires into the colour-coded holder, push the crystal head onto the prepared cable until fully seated, then secure the screw-on metal strain relief boot to prevent bending and improve shielding. The tool-less design allows quick assembly in the field; if re-terminating, the reinstallable shield can be removed and replaced without compromising performance.

What to consider before purchase

• Intended cable type: ensure you are using Cat6A or compatible solid/stranded cables (22–26 AWG)
• Required performance: purchase Cat6A-rated connectors only if you need 10 Gbps or higher throughput and improved EMI protection
• Form factor: this is an RJ-45 male crystal head (plug) — verify you need a plug rather than a jack, coupler, or pre-terminated cable

Recommendations

For best results use with ATEN 2L-29330 Cat6A cable or equivalent Cat6A-rated cable, follow standard wiring colour codes during termination, and avoid sharp bends near the strain relief to maintain signal integrity and PoE/POH reliability.
