Choosing between a connector and a cable isn't a normal side-by-side comparison. When you're sorting through control cables and connectors for industrial I/O, the first question isn't which part is better; it's which piece your wiring job is actually missing. The CNLINKO Circular Ethernet Industrial Connector is a single outdoor RJ45 male plug, while the Belden Industrial Control Cable is a bulk roll of control cable. One solves a connection point; the other solves the long run between points.
Quick Verdict
If your job needs a disconnectable RJ45 connection point outdoors, the CNLINKO plug is the targeted pick. If your job needs one long pull of control cable, the Belden roll is the bulk solution. They're not interchangeable, so your application determines the winner.

Product Notes
CNLINKO Circular Ethernet Industrial Connector
The CNLINKO Circular Ethernet Industrial Connector is the piece you grab when you want a clean, repeatable RJ45 connection in a place that gets wet or dusty. Its IP67 rating, combined with an ABS and zinc body, is the main reason to choose it for outdoor enclosures or exposed runs. The plug/unplug connecting mode makes it easy to disconnect equipment for service without disturbing the cable. It also carries UL, CE, and RoHS certifications, which matters when you're specifying industrial gear. The limitation is scope: at $9.49 you're buying one male plug, not a cable or a full mating set, so you'll still need a compatible jack or bulkhead to complete the link. If you're just looking for a short, waterproof, reusable connection point, this is the cheaper, more targeted buy.
Belden Industrial Control Cable
The Belden 2AS-1801POS-B-B/R Industrial Control Cable 1120A 01010000 is the bulk option for jobs that need length. The 482-foot roll gives you one continuous run for control wiring between panels, and the cable designation spells out the relevant specs: 18AWG conductor, 600V rating, TC, NPLF, and 90C dry/wet locations. At $641.24, you're paying for the full 482-foot roll, so it makes sense only if you have the room and the need for that much cable. The open-box condition is the main limitation to weigh; it's not a fresh sealed spool. If your project is a long industrial control run where you'd rather pull one continuous cable than splice short lengths, this Belden roll fits that task.
Final Choice by Use Case
Choose the CNLINKO connector if your setup is missing an outdoor RJ45 male plug and you want a connection point you can unplug and reconnect.
Choose the Belden cable if you're pulling a long run of industrial control cable and want to avoid piecing together shorter sections.
For most connector-versus-cable questions, the deciding factor is whether the job ends at a connection point or continues down the line.
