Anyone working with electronics in industrial environments knows that dust, moisture, temperature fluctuations and mechanical stress place significant demands on the enclosure. After all, it performs a vital role: protecting sensitive electronics and ensuring equipment continues to operate reliably over the long term.
But that is precisely what makes the difference. Not every plastic enclosure is suitable for demanding applications. Specially developed industrial enclosures, however, are designed to deliver the exact properties required to perform reliably under harsh operating conditions.
An enclosure for industrial applications must do far more than simply look good. What truly matters are technical properties that are carefully matched to its intended use:
Flame-retardant materials for maximum safety and compliance
UV-resistant additives, particularly important for outdoor applications
High impact resistance combined with a robust, durable construction
Reliable sealing against dust and moisture in accordance with IP ratings, achieved through screw connections positioned outside the electronics compartment
At the same time, practical implementation is equally important. Sufficient internal space for the electronics, secure mounting options for circuit boards and suitable surfaces for integrating interfaces, cable glands or control elements are all essential considerations.
Our range of accessories includes a master bracket/pipe bracket for the secure and stable mounting of IP-rated and robust enclosures on pipes or masts of various diameters.
The OKW portfolio includes a wide range of plastic enclosures designed for diverse industrial applications. Four series have proven particularly successful in air conditioning, heating and ventilation technology, mechanical engineering, measurement and control technology and smart factory environments:
SOLID-BOX: Elegant and robust (IP66/67)
SOLID-BOX combines robust technology with a modern design. It is suitable for both tabletop and wall-mounted applications and stands out for its sleek, high-quality appearance. Concealed screw connections ensure a clean, uncluttered design. From a technical perspective, it offers everything required for reliable everyday use in industrial environments:
• Protection ratings up to IP66/IP67
• IK08 impact resistance (equivalent to an impact force of 5 joules)
• Flame-retardant material with high heat resistance
A wide range of sizes also supports a standardised device design across different applications.
Versatile SOLID-BOX – robust, flexible and stylish
SMART BOX: Functional design with well-engineered protection (IP65/IP66)
SMART-BOX combines ergonomic design with a robust and durable construction. Its rounded contours create a modern, high-quality appearance while ensuring excellent mechanical performance.
Key design advantages include:
• Fold-down covers that fully conceal the screw connections
• Integrated lid locks that simplify assembly and maintenance
• Eight different sizes, providing flexibility for a wide range of applications
As a result, the SMART BOX provides a reliable and versatile foundation for many demanding industrial applications.

IN BOX: Versatile solutions for terminal block and electronics applications (IP66/67)
IN-BOX stands out for its exceptional flexibility. A wide selection of materials and sizes allows it to be precisely matched to the application, from compact installations to large-scale equipment.
Key highlights include:
• Two material variants with different impact resistance ratings (IK07 and IK08)
• Stainless steel quick-release fasteners for fast, efficient installation
• A comprehensive range of accessories, including DIN rails, mounting plates and sealing kits
An optional transparent cover adds further functionality, making the IN BOX particularly suitable for applications where visual inspection is required.

ROBUST BOX: Flexible modular system (IP66)
ROBUST-BOX lives up to its name, offering exceptional robustness combined with a high degree of flexibility. Both halves of the enclosure are threaded, allowing users to decide freely which side is used as the base and increasing adaptability during installation.
Key benefits include:
• A wide range of sizes, heights and material options
• Coloured bezels for clear colour coding or individual branding
• Accessories for wall mounting or DIN rail applications
Installation is carried out outside the sealed interior, ensuring that the IP66 protection rating is maintained reliably, even in demanding environments.

Customisation: From standard to bespoke solutions
A major advantage of modern plastic enclosures lies in their adaptability. Standard enclosures can be quickly and efficiently tailored to individual requirements:
• CNC machining, such as drilling or milling cutouts
• Printing with logos, data or multi-coloured designs
• Laser marking for permanent markings such as QR codes or barcodes
In addition, OKW offers a wide range of services to further optimise enclosures both functionally and visually:
• EMC coating to protect against electromagnetic interference
• Decorative foils in photo quality
• Assembly/installation involving screw fixing, bonding or fitting of accessories
👉 Conclusion:
Robust plastic enclosures are far more than a protective shell. They play a decisive role in the reliability and service life of electronic systems, particularly in demanding industrial environments.
Thanks to well-engineered designs, high-quality materials and extensive customisation options, modern enclosure solutions provide the necessary protection and flexibility to support reliable operation across a wide range of applications.
