12 ft Cat 5E Patch Cable

The Belkin A3L791-12-BLK is a Category 5E network cable built for standard Ethernet connections in home and office environments. It uses copper conductors and RJ45 male connectors on both ends to link computers, routers, switches or other network devices. The 12-foot length suits typical desk-to-wall or patch-panel runs.

Snagless Boot and Strain Relief

The moulded snagless boot protects the RJ45 locking tab from catching on adjacent cables or obstacles when the cable is pulled through trunking or across floors. A built-in strain relief stops the cable bending at a sharp angle where it meets the connector, reducing stress on the termination point and helping maintain signal integrity over time.

Simple Plug-and-Play Installation

No tools or configuration are required; push each RJ45 plug into a port until the tab clicks. The only common issue is forgetting to press the tab down before pulling the cable out, which can snap the tab off and leave the connector loose in the port.

Questions about this item

Will the RJ-45 connectors or the strain-relief boots need replacing after repeated plugging and unplugging?

The connectors are moulded with snagless boots and a strain relief that stops the cable bending sharply at the plug, so the termination points are protected from the wear that usually leads to replacement.

What performance limit appears first when the 12 ft cable runs at full speed all day?

PowerSum testing confirms the cable meets every Cat 5E electrical parameter, so the Category 5E specification itself is the ceiling you will hit before any length-related loss on a 12 ft run.

Does the unshielded 12 ft patch cable run warm or draw extra power when left connected continuously?

Passive copper patch cables generate no measurable heat and consume no power of their own, so a 12 ft Cat 5E run stays at ambient temperature regardless of how long it stays plugged in.
