A complete Klockner Bartelt control cable assembly for $159.99 faces off with a 482-foot Belden 18 AWG industrial cable roll at $641.24. Here's how to choose.

Last updated Aug 17, 2026

When you're wiring an industrial control panel, you often have to choose between a complete cable assembly and bulk wire. That's the fork in the road here. The Klockner Bartelt 500081 6 Industrial Control Cable Assembly and the Belden 2AS-1801POS-B-B/R Industrial Control Cable 1120A 01010000 ROLL OF 482FT are both built for industrial control and I/O wiring, but they ask you to do very different amounts of work. With about $481 separating the two prices, the decision comes down to whether you want a ready-to-install part or a long roll you can cut to fit.

Quick verdict

Go with the Klockner Bartelt 500081-6 if you need a ready-to-fit control cable assembly and you're replacing an existing part. Go with the Belden 1120A if you're starting fresh on a larger panel and need a continuous bulk run you can terminate yourself.

Product notes

#### Klockner Bartelt 500081 6 Industrial Control Cable Assembly

Klockner Bartelt 500081 6 Industrial Control Cable Assembly

If your Klockner Bartelt control setup takes the 500081-6 assembly, this is the direct route. It arrives as a preassembled control cable assembly, so you don't have to measure and terminate bulk wire. The catch is condition: this is a used unit, and multiple quantities may be available, so the exact unit you receive can differ from the one pictured. For a one-for-one swap on existing equipment, the assembly format is convenient, but you'll want to be sure the revision matches your gear before ordering. Used parts carry a little more uncertainty, so confirming compatibility is especially important here.

#### Belden 2AS-1801POS-B-B/R Industrial Control Cable 1120A 01010000 ROLL OF 482FT

Belden 2AS-1801POS-B-B/R Industrial Control Cable 1120A 01010000 ROLL OF 482FT

The Belden roll is built for bigger jobs. At 482 feet, it gives you enough 18 AWG cable for a long pull or several I/O drops, and the 600V TC, 150V NPLF, and 90C dry/wet ratings point to industrial control use. It's a new open-box roll, so the cable is unused even though the box has been opened. The main limitation is scale: a full 482-foot roll is a lot of cable to store and handle, and it's overkill for a single short repair. If you have enough cabling to justify it, the length and ratings make it a strong choice.

Final choice by use case

Use the Klockner Bartelt 500081-6 when you need a replacement assembly and you're working with equipment that uses that exact part. Choose the Belden 1120A when you're running new control cabling, can do your own terminations, and need the flexibility of a long bulk roll.
