When you're choosing components for control cables, connectors, and I/O hardware, the first fork in the road is whether you need a complete cable assembly or just the connector on the end. Two listings make that choice concrete: the Klockner Bartelt 500081 6 Industrial Control Cable Assembly at $159.99 and the CNLINKO Circular Ethernet Industrial Connector RJ45 Male Plug Outdoor Waterproof at $9.49. That large price gap is not a sign that one is better in every way-it signals that they solve different problems.
Quick verdict
If you need a complete replacement cable for an industrial control setup and you can verify the exact revision, the Klockner Bartelt assembly is the more complete choice. If you are building a weatherproof outdoor Ethernet connection and want a new, low-cost component, the CNLINKO plug is the smarter pick. In short: buy the whole assembly when you need the full run; buy the connector when you want to make your own run.
Side-by-side comparison
| Product | Price | Relative price | Condition | Key details | Best for |
|---|---|---|---|---|---|
| Klockner Bartelt 500081 6 | $159.99 | Used | Complete industrial control cable assembly with MPN 500081-6 | Replacing a full control cable run | |
| CNLINKO RJ45 Male Plug | $9.49 | New | IP67 waterproof, ABS & zinc body, UL/CE/RoHS, plug/unplug | Building an outdoor Ethernet connection |
Where each product wins
The Klockner Bartelt wins when you want a complete cable assembly and a specific part number for your maintenance records. Because it is listed as used, it fits replacement and repair work more than brand-new installations. The CNLINKO wins when you want a new, sealed RJ45 connector at a significantly lower price. Its IP67 rating and wide operating temperature range make it a strong fit for outdoor or industrial network runs.
Product notes
Klockner Bartelt 500081 6 Industrial Control Cable Assembly
This is the pick when your priority is a complete cable assembly rather than a connector you have to wire yourself. It is listed as used, so it suits maintenance and repair environments where you are replacing an existing run and already know the machine's configuration. The Klockner Bartelt brand and the 500081-6 part number give your purchasing team a concrete reference. The biggest limitation is that the listing describes a used item with possible multiple quantities, so exact revision and configuration should be confirmed before you order if your application needs a precise match. In other words, choose it when you need the whole cable and are comfortable with a used component.
CNLINKO Circular Ethernet Industrial Connector RJ45 Male Plug
The CNLINKO connector is a compact, new RJ45 male plug built for outdoor and industrial networking. Its IP67 rating covers water and dust resistance, and the -40°C to 80°C operating range makes it suitable for harsh environments. The ABS and zinc construction and plug/unplug connecting mode mean you can terminate it as needed. It also carries UL, CE, and RoHS certification. The trade-off is that this listing is for the connector only-you still need the cable and the tools to attach it, and it does not include a pre-made cable assembly. Pick it when you want a low-cost, weatherproof RJ45 solution and you are comfortable doing your own termination.
Final choice by use case
Choose the Klockner Bartelt 500081 6 when you need a drop-in replacement for an existing control cable and a documented part number matters more than saving money. Choose the CNLINKO RJ45 male plug when you are creating a new outdoor Ethernet connection and want a sealed, new connector that leaves cable selection and termination in your hands.
