The decision in the industrial robotics and cobots aisle is rarely about whether you need a robot-it's about what happens when a control unit in an existing cell starts to fail. If you are tracking down a Staubli RX90 CS7, you might be looking at a used 1997 controller with visible wear and asking whether it can fill the role. This listing gives you a specific candidate with two clear quirks: a dent on the corner and a missing key.
Quick verdict
At USD 2,499.99, this is a direct, no-extra-frills offering from American Industrial Supply Co. It is a used Staubli RX90 CS7 controller, not a new unit, and the listing is transparent about the condition: a dent on the corner and a missing key. For a maintenance or controls engineer who already supports RX90-class Staubli equipment, this can be a viable spare or replacement controller, provided the age and condition are acceptable. For someone expecting a ready-to-run robot arm or a newly refurbished controller, it is not that.
Who it suits
This purchase makes sense for teams with an existing Staubli RX90 6-axis setup looking for a CS7 controller, especially those comfortable with used industrial surplus. American Industrial Supply Co. describes over 25 years of experience in asset recovery and the decommissioning of warehouses and industrial sites, so the listing comes from a source familiar with taking apart industrial equipment. That context is useful, but it doesn't change the condition: the listed unit has a dent, a missing key, and only the items shown in the photos and listed above are included.
What stands out
The strongest point here is specificity. This is not a vague "robot controller" listing. It names the Staubli RX90, identifies CS7 controls, and includes the 6-axis description in the product title. The listing also flags the dent and missing key up front, and it explicitly says items not pictured or mentioned may not be included. That level of detail helps you set expectations before you commit, which matters when shopping for used industrial controls.
Meaningful trade-offs
The trade-offs are equally clear. First, this is a 1997 controller; electronics of that vintage may require expertise you already have in-house, but they are not a current-generation part. Second, the missing key and dent are physical limitations, not cosmetic afterthoughts-you may need to source a replacement key or work around the damaged corner. Third, the description states that only the items shown in the photos and listed above are included, which means you are buying exactly what is pictured and named, nothing more.
Bottom line
The Staubli RX90 CS7 at USD 2,499.99 is a very specific used controller for a very specific buyer. If your facility already works with Staubli RX90-class robots and you need a CS7 control unit, it is a credible used option to evaluate. If you are hoping for a complete 6-axis robot arm or a like-new controller, this listing will not close that gap. Weigh the dent and missing key against your own ability to integrate a vintage controller into your operation.
Staubli RX90 CS7 6-Axis Industrial Robot Arm Controller (1997)
This used Staubli RX90 CS7 controller is listed by American Industrial Supply Co. as an industrial surplus item with a dent on the corner and a missing key. Choose it when you need a specific RX90-class CS7 control unit and can accept the stated wear. Be cautious if you need a new unit or a complete robot arm; the listing clearly describes a used controller, and the included items are limited to what is shown and listed.
