When you're working with control cables, connectors, and I/O, the cable you choose can determine whether the connection works the first time or becomes a compatibility project. Two options sit close together in price: the Klockner Bartelt 500081-6 at USD 159.99 and the Keyence OP-87529 at USD 167.32. The price difference is only USD 7.33, so the real decision comes down to condition and specification clarity.
Quick verdict
If you want the lower price and can work with a used cable, the Klockner Bartelt 500081-6 is the less expensive choice. It includes physical dimensions and a specific MPN for reference. If you'd rather pay a little more for a new cable with a clear model and controller platform designation, the Keyence OP-87529 is the more straightforward match.

Product notes
Klockner Bartelt 500081-6
The Klockner Bartelt 500081-6 is the cost-conscious pick in this pair. Its USD 159.99 price is the lowest of the two, and the included dimensions give you concrete numbers for planning the install. The MPN 500081-6 also gives you a specific part reference. The trade-off is condition: this is a used cable, so exact revisions and compatibility should be confirmed before ordering. If you need a lower-cost cable for a retrofit and you're comfortable verifying match details, this one makes sense. Just keep in mind that the used condition means the exact unit can vary.
Keyence OP-87529
The Keyence OP-87529 is the new-condition option at USD 167.32. It is new, which removes the wear-and-tear question, and it includes a model number plus a controller platform designation of Automate. That makes it an appealing choice when the cable is meant to pair with a specific controller setup. The extra cost over the Klockner cable is modest, but the real consideration is fit: the model number is your primary compatibility reference, so confirm it matches your equipment before ordering. If you prefer a new cable with a clear model match, this is the one to choose.
Final choice by use case
- Choose the Klockner Bartelt 500081-6 when you want the lower price and you can work with a used cable that has published size specs.
- Choose the Keyence OP-87529 when you want a new cable with a direct model and controller platform identifier.
Either cable will fit into the control cables, connectors, and I/O product space; the right pick depends on whether you're optimizing for up-front cost or condition clarity.
