Harting is expanding the Han B product portfolio with the addition of a new locking system. The special feature of this system is that it is made entirely of a resistant elastomer. This provides high protection against external mechanical forces, as well as good resistance to oils and gases. A special contour and internal seal now enable the connection of two standard Harting 16B hoods while simultaneously achieving an IP 65 degree of protection. The device locks and seals in a single system, while housings can be quickly assembled and disassembled with minimal effort, all without tools. A further product variant also permits housings to be locked together with both bulkhead and surface mounted housings. A simple and robust locking element is particularly advantageous in stage technology, due to the risk of connectors falling from heights and the associated damage to the locking device upon impact. This impact can be prevented by the elasticity of the new product, which enables mechanical forces to be absorbed from the outside. Furthermore, extending cables in machinery is can be performed quickly and conveniently.
