In the case of the SKINTOP®HYGIENIC, class V4A stainless steel is used for the stainless steel body because it guarantees permanent corrosion protection and is able to withstand harsh conditions even in the long term. This, along with the use of sealing materials suitable for foodstuffs, makes the cable gland suitable for direct contact with food in production.
With the SKINTOP® HYGIENIC, the aim was to design a product without any corners or edges. This is because a cable gland in this sensitive area has to minimize the amount of ’attacking surface’ where impurities can accumulate. Therefore all seals are molded to seal the gaps between components perfectly without creating any cavities.
All threads are also fully covered. Additionally there is no hexagon on the cable gland – instead, each one has two flat surfaces to which screws can be fixed. Corners, edges, cavities and grooves in which microbes might settle are prevented in this way. Additionally, both flats were rounded and the surface roughness was minimized because microorganisms can settle on rough surfaces and biofilms can form. “Hygienic Design” is the term for it.
