Data For Our U-Case 1 Aluminium Electronic Enclosure
Silver or black anodized combination extruded and sheet aluminium box to take circuit boards of width 100mm, 128mm, 160mm and 220mm and length 80mm, 120mm, 160mm and 220mm.
The box comprises a pair of extruded aluminium sides of height 44mm which accept an aluminium top and bottom plate to form a box section. Front and rear plates are fixed into the side extrusions to form the enclosure and retain the top and bottom plates. The maximum height of components on a board mounted in the bottom slot is 32mm. The enclosure could be used as a back box for a 1U 19” rack front.
The box was originally designed for a specific application, but some extra flexibility has been incorporated. Internally it features assorted slots and a bracket for optionally holding a standard size hard drive. There is an image with the hard drive on the website. The outside of the box features a pair of dovetail slots which will accept a Linc-lug mounting bracket.
Length Tolerance of extrusion: Nominal length +/-0.3mm e.g. U1S160 is not shorter than 159.7mm and not longer than 160.3mm.
Non-Standard Sizes: Available.
Material of extrusion: Aluminium 6063 T6 (HE9), silver anodized 5μm or black anodized 15μm to BS1615. Linear weight is 0.40 kg/m.
Material of end plate: Aluminium 5251 H22 sheet 1.5mm thick clear anodized 5μm or black anodized 15μm.
Material of top/bottom plate: Aluminium 5251 H22 sheet 1.5mm thick clear anodized 5μm or black anodized 15μm.
Screw ports: Nominal diameter 2.7mm to take a No.4 self tapping screw with a 3.0mm major diameter of a type normally used for plastic. The screw ports can be threaded M3 using a thread-rolling tap, but a thread cutting tap will make a weak thread. Alternatively an M3 thread-forming screw can be used to roll its own thread.

Box comprises (all items silver):
2 x End plates, Top Plate and Bottom Plate, 2 x U-Case extrusion, 8 x screws. Screws – 3.0 x 10 Posi-pan head self-tapping screws type AB:
Natural aluminium carrier plates the same size as standard circuit boards to slide in the enclosures and be adapted to carry non-standard circuit boards and other fittings. These are simple rectangles of aluminium sheet 1.5mm thick for internal use (i.e. surface finish may not be perfect). LSS40 and LSS80 (silver) or LSB40 and LSB80 (black) Linc-Lug wall mounting brackets will fit in the dovetail slots.
