Network cable ACT DA5903 Cat6a U/FTP (STP) 3 m, RJ-45 to RJ-45, gold-plated contacts, black

ACT DA5903 is a 3 m Cat6a U/FTP (STP) slimline patch cable designed for high-speed Ethernet links in environments where space and airflow are important. The cable has a reduced outer diameter of 3.8 mm and two 90° angled down RJ45 connectors, making it suitable for tight rack and cabinet installations while maintaining the required bend radius. The LSZH jacket minimises the release of toxic gases in case of fire. Full-copper 32 AWG conductors and 50 µm gold-plated RJ45 contacts ensure reliable signal transfer and compliance with international standards.

Advantages

The slim 3.8 mm diameter improves airflow in server racks and network cabinets and reduces cable bulk compared with standard Cat6a patch cords. Two 90° down-angled RJ45 connectors allow neat routing behind equipment and in confined spaces without compromising the bend radius. The LSZH outer jacket lowers the risk of high concentrations of toxic gases if the cable is damaged by fire, and full-copper 32 AWG conductors with 50 µm gold-plated contacts provide stable electrical performance and corrosion resistance.

Suitable for

• High-speed Ethernet connections (up to Cat6a performance) between switches, patch panels and servers
• Installation in server racks and network cabinets with limited space
• Patch cabling behind equipment where angled connectors help routing
• Environments where low-smoke, zero-halogen jackets are preferred for safety

When it may not be suitable

The slimline 3.8 mm cable is optimized for space-constrained installations; however, in applications requiring very long cable runs, in-line cable management systems that expect standard cable diameters, or where shielding configurations differ, a different cable type or standard-diameter Cat6a cable may be preferable. Also, if a different connector orientation (straight, 90° up, left or right) is required, choose the matching variant instead of this 90° down-to-90° down version.

Key specifications

• Cable category: Cat6a U/FTP (STP)
• Length: 3 m
• Outer diameter: 3.8 mm (slimline)
• Conductors: full copper, 32 AWG
• Connector type: RJ45 angled 90° down to RJ45 angled 90° down
• Contacts: 50 µm gold-plated
• Jacket material: Low Smoke Zero Halogen (LSZH)
• Colour: Black

How to use

Connect one RJ45 angled down connector to the network port of a switch, patch panel or device and the other end to the corresponding port. Route the slimline cable through the rack or cabinet, using the reduced bend radius to maintain tidy cable runs and preserve airflow. Ensure connectors are fully inserted and clicks are audible. Avoid sharp bends beyond the specified bend radius and secure cables with appropriate management accessories to prevent strain on the connectors.

What to consider before purchase

• Required connector orientation — this product has RJ45 90° angled down connectors on both ends
• Compatibility with rack/cabinet cable management and required cable diameter
• Length needed (this model is 3 m)
• Need for LSZH jacket in your environment for fire safety considerations

Usage recommendations

Use the ACT DA5903 in dense rack or cabinet installations to improve airflow and reduce cable congestion; select the appropriate connector orientation and length to match your equipment layout and cable management strategy.
