The decision: ready cable assembly or bulk spool?
When you're buying for control cables, connectors, and I/O wiring, the first fork in the road is usually whether you need one complete, machine-specific cable assembly or a big length of wire to cut and terminate yourself. These two candidates sit on opposite sides of that choice. One is a finished component; the other is raw material. The right pick depends on how much wiring you're doing and whether you want a ready-made part.
The Klockner Bartelt 500081-6 Industrial Control Cable Assembly carries a specific manufacturer part number. The 850 ft Full Spool black Amphenol Industrial Wire/Cable is a full spool of black wire. The price gap is roughly $69, but the deciding factor is the job you're doing.
Quick verdict
- Pick the Klockner Bartelt 500081-6 if you want a defined assembly with a known part number and you're comfortable with used equipment.
- Pick the Amphenol spool if you need lots of bulk wire to cut to length for custom wiring runs.

Product notes
Klockner Bartelt 500081-6 Industrial Control Cable Assembly
This is the complete-unit option. At $159.99, you're paying for a specific Klockner Bartelt cable assembly identified by MPN 500081-6, made for pneumatic, hydraulic, electronic, and electrical control equipment. Because it's a used unit, the practical move is to confirm exact revisions and compatibility before ordering when your application requires a precise match. It's the right fit when you want a drop-in cable assembly rather than raw wire that still needs cutting, stripping, and terminating. The trade-off: you get one assembly, not a long spool, and used condition is a legitimate consideration if you prefer not to buy pre-owned parts. The used condition is the main reason to double-check before you order.
850 ft Full Spool black Amphenol Industrial Wire/Cable
The Amphenol spool flips the equation. At $91.00, it gives you roughly 850 feet of black wire in new - open box condition, with a 3-pin design and wire-compatible mounting. That makes it the stronger choice for custom-length runs, control panel wiring, or any job where you'll cut and terminate each run yourself. Because the unit type is feet, you can plan the exact lengths you need. You're not buying a finished assembly, so factor in the connectors and terminations you'll need on top of the wire. The open-box condition is part of the deal, and the trade-off is accepting that you're buying material rather than a finished part. If your project has several identical runs, having one full spool simplifies planning.
Final choice by use case
If you need to replace one specific control cable on an existing machine, the Klockner Bartelt 500081-6 assembly is the direct part to evaluate first. If you're running multiple wire lengths or building out a control cabinet, the Amphenol spool gives you far more material to work with. Think of the assembly as the service part and the spool as the raw stock; that distinction settles most control wiring decisions.
