General Modular Accessories from Robotunits

Robotunits General Modular AccessoriesEvery small detail has a big impact on the entire system, especially when countless accessories fill hundreds of catalog pages. Developing a new part for every new application in the industry, machine construction, or production is fundamentally contrary to our idea of a compatible modular system. That’s why our accessory parts perform several functions at once in the Robotunits Modular Automation System. This also applies to our aluminum extrusions and fasteners.

General Modular Accessories Q & A

+ What exactly are “general modular accessories,” and how do they fit into the system?
The general modular accessories are components that complement the aluminium‐extrusion and fastening modules in the Robotunits Modular Automation System. They include items like hinges, floor fixings, door components, surface panels, cover & insert extrusions, and other accessory parts that work alongside the core extrusion and fastening profiles. These accessories allow you to complete and customize assemblies built from the 40 mm and 50 mm series extrusions.
 
+ Are the accessories compatible with both the 40 mm and 50 mm series extrusions?
Yes — the system is designed so that the extrusions in the 40 mm and 50 mm size series share a common T-slot size of 14 mm, allowing compatibility and interchangeability of accessories across the series. This means many accessories will work across both series, facilitating flexibility in design.
+ What should I consider when selecting accessories (e.g., load ratings, finish, installation)?
When selecting accessories, you should consider the mechanical requirements — for example, whether the accessory will need to bear loads, withstand vibration, or be used in a safety-critical environment. Also, you should consider the surface finish and environmental suitability, such as whether it will be exposed to corrosion, chemicals, or require a hygienic finish. It’s important to verify the installation method and fit, ensuring that the accessory aligns correctly with the extrusion system and fastening components (for exampl,e matching the T-slot dimensions and profile orientation). Practical considerations include checking whether spares are available, the lead time, and whether the accessory is part of the standard catalogue or requires custom modification.
 
+ Can I retrofit accessories to an existing Robotunits extrusion structure?
Yes — one of the advantages of a modular system like Robotunits is that accessories can typically be added or retrofitted. Because the system uses standardized slot sizes and modular profiles (40 mm/50 mm with 14 mm T-slot) you can add accessories to an existing frame without fully rebuilding the structure. However, you should verify that the particular accessory you want is compatible with your series and does not interfere with existing load paths or structural integrity.  
 
 
+ How do I find drawings/specifications and ensure the accessory will fit my design?
To find drawings and specifications and ensure the accessory will fit your design, you should download the catalogs or specification PDFs provided by the manufacturer, which include dimensional drawings (slot width, profile depth, and connector geometry) and other technical details. Then you should confirm the accessory's load ratings and capacity to determine if it will bear structural loads. Use any available product configurator or contact Valin to verify that the accessory corresponds to your profile series (for example 40 mm vs 50 mm) and slot size. If there is any doubt, reach out to Valin to double-check compatibility.
