When you're shopping in the industrial robotics and cobot space, the decision usually comes down to one question: will this arm move the right parts at the right weight without becoming a project of its own? The Denso VS050A3-AV6-NNN-NNNAN-NNNN (6F13005) makes that question very concrete. It's a used Denso robotic arm assembly with a 4 kg payload, coming out of the Japanese industrial automation equipment market, and it's offered at USD 1,500.00.
Quick verdict
If your application involves small parts, pick-and-place work, or light assembly, the Denso VS050A3 is a reasonable arm to consider. The 4 kg payload is enough for many compact components, and the used Japanese automation equipment market is a familiar one for industrial buyers. At USD 1,500.00, this arm sits in a practical price window for a targeted production cell or an automation pilot. The catch is that you're buying an arm assembly, not a finished workcell, so you should have a clear picture of how it will be integrated and controlled.
Who it suits
This arm suits a team that already has experience with used industrial robots and knows how to bring a standalone arm into a production line. It also makes sense for applications where the parts stay comfortably under the 4 kg payload ceiling. If you're building a small handling station and the Denso Industrial name and Japan origin match your sourcing preferences, the VS050A3 fits that profile.
Product at a glance
Denso VS050A3-AV6-NNN-NNNAN-NNNN (6F13005)
This unit is the Denso VS050A3-AV6-NNN-NNNAN-NNNN, with the model line also carrying a 2020 identifier. The unit is classified as a robotic arm assembly with a robotics controls type of "Arm," and the payload is rated at 4 kg. The country of origin is Japan, and the unit is in used condition. In short, the product is the arm itself, not a complete station with peripherals included. That distinction matters because it defines the scope of your project.
Choose this arm if you have a specific cell design that needs a light 4 kg robotic arm and you're comfortable building the supporting system around it. The clearest trade-off is the standalone nature of the unit: a used arm assembly demands a solid integration plan for the surrounding equipment, and a 4 kg payload is not intended for heavy material handling. Stay within the payload and keep the application focused, and the Denso VS050A3 can be a practical piece of your automation puzzle.
What stands out
The strongest points from the product details are the Denso Industrial brand, the 4 kg payload, and the Japan origin. The 4 kg capacity at this price point is a realistic match for light-duty work. The "robotic arm assembly" classification also tells you exactly what you are working with, which is useful in a market where full systems and bare arms are often mixed together.
Meaningful trade-offs
On the other side, used condition is a normal consideration for any pre-owned robot, and the standalone arm format means you should already have the rest of the automation ecosystem in mind. The 4 kg capacity is a hard limit, not a suggestion, so you need to know the weights of your parts and end-of-arm tooling before you commit.
Bottom line
The Denso VS050A3-AV6-NNN-NNNAN-NNNN is a straightforward used robotic arm option for light industrial automation. If the 4 kg payload matches your parts, the arm deserves a spot on your shortlist. Plan for the integration work, keep your application within the rated capacity, and this arm can earn its place in a compact automation cell.
