Quick verdict
When you are shopping for control cables, connectors, and I/O for industrial equipment, a used assembly can be a good fit if it is the right model. This Klockner Bartelt 500081-6 control cable assembly at USD 159.99 is a practical candidate if you need a replacement for a Klockner Bartelt system. It is described for use with pneumatic, hydraulic, electronic, and electrical control equipment, so it fits an industrial control panel or machine where multiple control signals come together. Because it is used and exact revisions can matter, the sensible move is to confirm compatibility before ordering.
Who it suits
This cable assembly suits technicians repairing Klockner Bartelt equipment, engineers rebuilding control panels, and maintenance teams that need a spare for a 500081-6 application. It is also a reasonable fit for shops that already have matching connectors and need a serviceable replacement without waiting for a new build.
What stands out from the listed details
The strongest points are the specific model identity and the range of control types it is described for. Klockner Bartelt, MPN 500081-6, in used condition, is described for pneumatic, hydraulic, electronic, and electrical control equipment. The item also says to verify exact revisions and compatibility before ordering when your application requires a precise match. That makes this a part for buyers who can confirm the variant they need.
Meaningful trade-offs
Buying used means you are not getting a factory-new cable that has never been installed or handled. The prior service history is not included, so you should inspect the assembly and judge it against your own requirements. The limitation is not the price but the verification step: for a control system where a mismatched revision can cause issues, you need to confirm that the 500081-6 variant you receive is the right one. The item makes this point clearly, so treat this as a part that requires a compatibility check rather than a blindly universal replacement.
Bottom line
At USD 159.99, this Klockner Bartelt 500081-6 industrial control cable assembly is a solid option for buyers who know exactly what they need. If you are comfortable confirming the revision and inspecting the used part, it can be a practical way to keep control equipment running.
