The enclosures of the Spelsberg TK series, tried and tested by decades of experience, are true all-rounders. They are available in entirely different dimensions from 50 x 52mm to 360 x 254mm and with three cover heights. In plastic, using the materials polycarbonate and polystyrene, all sizes are available. Produced from glass-fibre reinforced polycarbonate, with IK 08 they are able to withstand even tough industrial environments, are weatherproof, impact-resistant, and with IP 66 also well suited for use on protected external walls.
The enclosures can be adapted to the particular application in question using the comprehensive range of accessories, from the assembly plate through a wide array of cable insertions and up to the external hinges. Upon request from the customer, Spelsberg is also able to make custom adaptations, so that the TK series can also be used for tailor-made solutions.
However, plastic is not always the first choice of material. Up until now, if particular resistance to chemicals was needed for some sectors, it was the end of the road for the TK series. Also when it comes to impact resistance the plastic variants have natural limits. And in respect of shielding from electromagnetic interference the use of metal enclosures is also preferred, as these often make additional shielding measures redundant.
Spelsberg has therefore added some aluminium variants to the popular TK range. For why these solutions were integrated into the TK series and not into their own separate range, we hear from Michael Schwabe, Key Account Manager for Enclosure Solutions:“Our range for the TK series includes a comprehensive selection of accessories, which can be used to outfit each enclosure exactly as you need. We wanted to open this option to the aluminium variants as well, without unnecessarily increasing inventory at our customers and retail partners.”
For this reason the internal dimensions of the new variants are the same as the plastic variants, so that the many existing different types of assembly plates can be used, for example. “Only the outer dimensions vary, as the wall thicknesses are greater for aluminium than plastic”, explainsWasserfuhr.
The new enclosures have protection class IP 66, and IK 09 makes then especially robust.
Of course the spacings for the wall attachment holes in the bottom of the enclosure are also identical to those in the plastic housing. This makes swapping them out an easy proposition.
