Constant innovation leads to better enclosures for today’s electronics – Electronics World

OKW, Marketing Director, Robert Cox

The design of industrial electronic enclosures has been dominated by elegant panel PCs and touch screen housings in recent years.Their clean lines and sleek contours transformed automation, robotics, and state-of-the-art mechanical control in 21.st The smart factory of the century.

But what about the die-cast aluminum enclosures that precede them? Has their innovation journey reached its peak? Absolutely not-because the latest IP rated housings are certainly die-cast-and they are full of smart design features.

Having transformed the design of industrial electronic enclosures for over 30 years, Rolec has launched a new generation of rugged, ubiquitous housings for walls, bulkheads, machines and desks. Its aluDOOR (IP 66/67 / 69K) is effectively a “compact cabinet” with an innovative lid featuring a cleverly integrated hinge design. The lid opens 100 ° for easy access. Can be specified with or without a recess for the membrane keypad or product label. A2 stainless steel lid screws and threaded inserts ensure corrosion resistant assembly in extreme conditions.

Installing the lid is quick and easy. Use the integrated hinge pin to push the lid into place and secure it with two tamper-proof Torx T25 (M5) screws. Then close the lid and lock it with two more T25 screws. Extruded aluminum trim hides and protects the fixture.

The seal is a new foamed polyurethane gasket that is continuous for added protection. There are no joints that could ultimately be a weakness. Also, like many other Rolec die-cast enclosures, aluDOOR has a separate mounting screw channel that allows it to be mounted “closed” and protects electronics and seals.

Design a positive mindset

The new aluDOOR is an important step forward in enclosure design, but its innovation is underpinned by a long history of positive thinking. These innovations date not only to the launch of Rolec in the 1980s, but also to the 1960s, when the company’s founder, Friedhelm Rose, first became an entrepreneur. Not impressed by the plain boxes available at the time, Fried Helmrose announced an innovative new design to rewrite the rulebook. It was 1967, the avant-garde highest point of 10 years, which is synonymous with design innovation. For Friedhelm Rose, 1967 was the dawn of the “Age of the Enclosure.”

A few years later, the enclosure that changed everything was aluCASE (IP 66/67 / 69K). This is a very advanced and popular model and remains in the range of Rolex’s premium diecast enclosures. Its technical features set the tone for decades to come: Closure-closed mounting, clip-on trim to hide fixing and mounting screws, lid-holding straps, membrane keypads or generous product labels. Closure Recess-Many of these benefits are found throughout the series of Rolec enclosure models.

One such model is aluDISC (IP 66/67 / 69K). This is the world’s first round die-cast enclosure for industrial electronics. In particular, the aluDISC is not really a circle, so it’s a remarkable achievement. Its main display area is certainly round, but the enclosure requires flat edges to attach the connector, so Rolex was inspired by the shape of the watch. Extend the circle instead of square it. On the other hand, it maintains the “roundness” of the design language.

On the other hand, the aluCLIC (IP 66/67 / 69K) enclosure has its own advantages. You can clip it to the base plate for quick installation (and you can clip it off just as quickly). This is essential in extreme outdoor environments. The enclosure remains sealed until it can be opened in a safer place.

However, not all industrial enclosure models can be installed with the lid closed. Some will benefit from a patent registered by Fried Helmrose in 1985. This is a single channel that can accommodate both mounting and lid screws. This frees up space within the enclosure and allows device designers to specify a more compact housing.

Another Rolec innovation solves the challenge of how to protect fragile EMC shield gaskets. Traditionally, these gaskets are vulnerable to breakage if the lid is opened regularly for inspection. Rolec’s solution was to eliminate the need for EMC gaskets altogether. Its conFORM (IP 66/67) and conTROL (IP 66/67) diecast enclosures feature a built-in EMC shield, thanks to a patented tooth system precast on the lid and base. The teeth engage, maintain electrical continuity, and ensure long-term reliable integrity of the Faraday cage.

However, not all advanced industrial enclosures are die-cast. Extruded aluminum enclosures have significant advantages over castings because they are custom-made in length and can be manufactured in a faster and more cost-effective manner. No additional tools are needed. Extruded enclosures such as aluDISPLAY (IP 54) and mobilCASE (IP 54/65) also allow for rapid PCB installation. The circuit board simply slides in and out on the guide rails that form part of the extrusion profile.

And when it comes to custom sizes, the latest command enclosures grab the crown. Both Rolec’s multiPANEL (IP 65) and profiPANEL (up to IP 65) can be specified in any plan size up to 800 x 800 mm to the standard closest millimeter. They can be attached to suspension arms, wall connectors (because they rotate around a vertical axis) and mounting brackets.

The premium multi-panel provides a flash fit of the front plate or glass panel and a virtually borderless installation, enabling flash integration of the display or touch screen housing with the PC. The structure is based on an extruded aluminum profile with stainless steel trim for ultra-modern aesthetics. And while as attractive as multiPANEL, it is profiPANEL that offers more versatility. The standard depth range is wider. profiPANEL combines two profile widths (60mm and 90mm) to create nine standard depths from 60mm to 300mm. Options also include a keyboard desk with a large capacity to fit the main enclosure.


No matter which standard enclosure you specify, it makes sense to order it completely customized. This allows you to move directly from Goods In to the production line to install components and accelerate production to increase production. Customizing standard enclosures has never been easier. No much customization is required to transform an off-the-shelf enclosure into a fully branded enclosure designed for a particular application. Advances in technology have made customization possible in smaller batches and are within the reach of specialized electronics manufacturers who create niche products.

By partnering with a professional enclosure manufacturer, you can provide all services under one roof and pay dividends. Single source suppliers such as Rolec do everything they need to do, including CNC machining (drilling and tapping, notches, indentations, contour milling machines), branding of custom color enclosures using powder or wet paint. Can be executed. Digitally print legends, logos, and photo-quality graphics. This process is much more efficient than traditional methods and allows printing in much smaller quantities. Other options include engraving and laser machining.

Enclosures can also be specified with display windows, EMC shields, and various accessories such as cable glands, hinges, mounting rails, and terminals. All of these can be assembled.

Rolec is represented by OKW Enclosures in the United Kingdom.
