Frequently Asked Questions

Choosing the right enclosure material depends on your application and the environmental conditions. Generally, aluminium, plastic or polyester enclosures are used. Each material has specific properties and is suitable for different applications.

The following factors, amongst others, play a role in the selection process:
• Indoor or outdoor use
• UV radiation, humidity and temperature
• Chemical exposure
• Mechanical stress
• Required protection rating 

Our experts will be happy to help you select the ideal material for your application.

The required protection rating depends on the environmental conditions to which the enclosure is exposed. Depending on the product, ROLEC offers protection ratings ranging from IP 54 to IP 69K, providing solutions for a wide variety of applications – from dusty production environments to high-pressure cleaning.

ROLEC enclosures are designed for continuous use in demanding industrial environments. Their mechanical robustness is described, amongst other things, by the IK protection rating and depends on the material, design and application.
We would be happy to recommend the right enclosure solution for your mechanical requirements.

Yes. On request, we can supply your housing fully machined and ready for assembly.

Our range of services includes, amongst other things:
•    Drilling, milling and thread cutting
• Cut-outs for displays and control elements
• Integration of HMI components
• Engraving, screen printing and digital printing
• Customised surface finishes 

This means you receive a complete, ready-to-install solution from a single source.

The durability of an enclosure depends on the material used and the specific operating conditions.

Factors that influence this include, for example:
• Chemicals and cleaning agents
• UV radiation
• Moisture and salt water
• Temperature
• Mechanical stress 

Your personal contact will help you select the right material for your application.

Depending on the product, various approvals and certifications are available.

Yes. ROLEC offers specialised EMC enclosures that reliably protect sensitive electronics from electromagnetic interference. The conFORM and conTROL series are unique standard EMC enclosures that do not require any additional, expensive sealing solutions.


Depending on the product, various shielding concepts are also used, such as conductive seals or a special EMC coating. As a result, many of our enclosures are particularly suitable for applications with high electromagnetic compatibility requirements. We would be happy to advise you on selecting the right EMC solution!

The lead time depends on the enclosure series selected and the extent of the required finishing. Many standard enclosures are available at short notice. Customised solutions involving machining, labelling or assembly may take slightly longer, depending on the project.
