ACT DA4951 Cat6a U/FTP (STP) networking cable 1.5 m, RJ‑45 to RJ‑45, black, gold‑plated contacts

ACT DA4951 is a 1.5 m Cat6a U/FTP (STP) slimline patch cable with a straight RJ‑45 connector on one end and a 90° angled up RJ‑45 connector on the other. The cable is designed for 10 Gigabit Ethernet and professional network environments such as server racks, switches and patch panels. Its reduced outer diameter improves airflow in cabinets while the LSZH jacket lowers the risk of toxic gas release in case of fire. The cable features full copper 32AWG conductors and 50 µ gold‑plated RJ‑45 contacts for reliable connections and complies with international standards.

Advantages

The slimline design (3.8 mm outer diameter) and smaller bend radius save space behind equipment and inside racks without compromising signal integrity. Shielding (U/FTP) provides improved immunity to electromagnetic interference. The LSZH jacket minimises hazardous emissions in fire scenarios, and gold‑plated contacts with full copper conductors ensure stable, low‑loss connections suitable for high‑speed links.

Suitable for

• 10 Gigabit Ethernet connections in server racks and data centres
• Connecting switches, patch panels and network equipment where space is limited
• Professional installations requiring shielded cables to reduce EMI

When it may not be suitable

This slimline Cat6a U/FTP cable is not intended for environments where extreme mechanical protection or very long cable runs are required; its thinner jacket offers less crush resistance than thicker cables. It is also unnecessary for basic home networks that do not require 10 Gbps throughput or shielded cabling.

Key specifications

• Category: Cat6a U/FTP (shielded)
• Length: 1.5 m
• Conductors: solid full copper, 32 AWG
• Connectors: RJ‑45 straight to RJ‑45 90° angled up
• Contact plating: 50 µ gold plated
• Jacket: LSZH (Low Smoke Zero Halogen)
• Outer diameter: approx. 3.8 mm
• Colour: black

How to use

Plug the straight RJ‑45 end into the patch panel, switch or device port and insert the 90° angled RJ‑45 end where space behind equipment is restricted. Ensure connectors are fully seated and avoid sharp bends beyond the cable’s bend radius. Route the cable along existing pathways in racks or cabinets to maintain airflow and minimise interference with other cables.

What to consider before purchase

• Required throughput (supports up to 10 Gigabit Ethernet)
• Need for shielding to reduce EMI in the installation
• Available space behind devices and preferred connector orientation
• Environment requirements for low‑smoke cabling (LSZH)

Usage recommendations

Use the 90° angled end where clearance is limited and keep the slim cable routed to improve rack airflow; avoid tight pinch points and maintain gentle curves to preserve performance.
