IP66 stainless steel keypads AISI 304 (X5CrNi1810 1.4301 UNI EN 10088-1) finely satin-finish stainless steel junction boxes, of a sturdy construction, made from a single, 1.2 mm thick sheet of stainless steel. This is trimmed, pressed and then welded in an inert environment in order to prevent the possibility of corrosion. A neoprene rubber seal that is both oil resistant and self-extinguishing, and pre-fitted into the lid ensures IP66 water tightness. They come complete with leakproof screws to fasten the lid and grounding as required by law. M6 stainless steel stud bolts are placed on the base of the boxes to attach the frame and base plates (except for COD. 6410E01 and COD. 6411E01). The 6411 series is drilled on the lid for a diameter dimension of 22.5mm; the location of the holes can be identified by referring to the tables and drawings above. The kits to attach to walls COD. 6412F must be requested separately and they can be attached easily by piercing a hole for a diameter dimension of 8mm; IP rating is guaranteed by the leakproof seals included inside the kit.
