Feature: Enclosures


Premium multiPANEL offers flush-fit


Unimpressed by the plain boxes available at the time, Friedhelm Rose launched a radical new design that would rewrite the rulebook


and virtually borderless installation of a front plate or glass panel – enabling the housing of displays or touchscreens and the flush integration of PCs. Construction is based on extruded aluminium profile with stainless-steel trims for ultra-modern aesthetics. And, as attractive as multiPANEL is, it’s profiPANEL that offers more versatility. Te range of standard depths is greater; profiPANEL combines two profile widths (60mm and 90mm) to create nine standard depths, ranging from 60mm to 300mm. Options also include a sizeable keyboard desk to match the main enclosure.


Customisation Whichever standard enclosure is being specified, it makes sense to order it fully customised so it can go directly from Goods In to the production line for installation of components – accelerating production and boosting output. Customising standard enclosures is


HMI and diecast enclosures supplied fully customised to individual specifications But not all industrial enclosure models


have ‘lid closed’ installation; some benefit from a patent that Rose registered in 1985 – a single channel that accommodates both mounting screws and lid screws. Tis frees up space in the enclosure, allowing for a more compact housing.


Rolect innovations Another Rolec innovation solves the challenge of how to protect notoriously fragile EMC shielding gaskets. Tey are prone to breakage if the lid is opened regularly for inspection. Rolec’s solution was to dispense with EMC gaskets altogether. Its conFORM (IP 66/67) and conTROL (IP 66/67) diecast enclosures feature built-in EMC shielding thanks to a patented tooth system pre-cast into the lid and base. Te teeth interlock, preserving electrical continuity and ensuring the reliable integrity of the Faraday cage over the long term.


However, not every advanced industrial


enclosure is diecast. Extruded aluminium enclosures have a significant advantage over their cast counterparts, because they can be produced faster and more cost effectively in bespoke lengths – without extra tooling. Extruded enclosures such as aluDISPLAY (IP 54) and mobilCASE (IP 54/65) also enable the faster installation of PCBs: circuit boards simply slide in and out on guide rails that are already part of the extrusion profile. And, when it comes to bespoke sizes,


the latest command enclosures hold the crown. Rolec’s multiPANEL (IP 65) and profiPANEL (up to IP 65) can both be specified to the nearest millimetre – as standard – in any plan size up to 800 x 800mm. Tey can be mounted on suspension arms, wall connectors (for pivoting about the vertical axis) and mounting brackets.


now easier than ever. It doesn’t take much customisation to transform an off-the-shelf enclosure into one designed for a specific application and fully branded. Advances in technology have made customisation easy for smaller batches, bringing it within reach of specialist manufacturers creating niche products. Partnering with a specialist enclosures


manufacturer pays dividends because they can offer the full range of services under one roof. A single-source supplier such as Rolec can carry out all the required work: CNC machining (drilling and tapping; milling cutouts, recesses and contours, etc.), and branding enclosures in custom colours using either powder coating or wet painting. Legends, logos and photo- quality graphics can be digitally printed, which is a much more efficient process than traditional methods, enabling printing in lower volumes. Other options include engraving and laser processing. Enclosures can also be specified with


display windows, EMC shielding and a wide range of accessories such as cable glands, hinges, mounting rails and terminals – all of which can be assembled. Rolec is represented in the UK by OKW Enclosures.
