First rear Mounting options for Han Metal Hoods and Housings

April 1, 2019

With the new Han metal housings, it is possible to lock the prefabricated inserts directly from the rear into the bulkhead mounting housing from the interior of a control cabinet. In the past, Han inserts had to be conducted from the inside of the cabinet through the panel cutout, before they could be preassembled outside. After that, they were pushed back and fixed into the bulkhead mounted housing.

In the new metal hoods and housings, the insulation bodies are inserted into a plastic holding frame that snaps safely into the aluminum die-cast enclosure, supported by a lug. In order to achieve protection in accordance with class IP65/66 and also to guard against the effects of UV radiation and ozone, the flange rubber seal is laid completely into the interior of the housings. The housings of the Han M series were redesigned according to the same principles. The Han^® M hoods and housings differ from their Han B counterparts only by the fact that they are even more suitable for harsh environments, for example, on the exterior of wind turbines.

By the end of this year, rear mounting inserts with a continuous 360° degree shielding will also be available. With Han EMC, the shielding is always on the metal hood or housing. The hoods, in addition, need special EMC cable glands.

With the new mounting options, the preassembly of cabinet components becomes increasingly efficient, as more elements of control cabinets, machine modules and cable harnesses can now be prefabricated separately. As a result, the proportion of prefabrication increases and the overall assembly costs decrease. For an inexpensive introduction into manufacturing, the new and old variants of the Han^® metal hoods and housings are consistently compatible with each other.
