Die-Cast Enclosures in Unusual Shapes

Responding to customer requests from several different sectors for die-cast enclosures to provide a strong and robust, environmentally sealed housing with good EMC screening in a non-rectangular shape, Hammond Electronics has extended its popular 1590 family with the introduction of the 1590TRP and STP models. The first applications for the new shapes have been for audio equipment, guitar stomp boxes, industrial remote controllers, desktop switch arrays and handheld test equipment controllers.

The octagonal 1590TRP is 133 mm across the flats and 39 mm high, and will house a circular PCB up to 126 mm in diameter. The two trapezoidal units are also 39 mm high; the smaller portrait format unit is 112 mm long, narrowing from 79 mm to 62 mm, while the larger landscape format one is 95 mm deep and narrows from 151 mm to 122 mm.

All three types are available in natural finish and in a smooth gloss polyester powder paint, which does not chip after machining and provides a good surface for labels and silk screening. The strong and vibrant painted colours are black; cobalt blue, RAL 5013; green, RAL 6024; light grey, RAL 7035; orange, RAL 2009 and red, RAL 3011. A lap joint seals the units to IP54, protecting against the ingress of dust and water, and the painted finish is only applied to the external surfaces, maintaining RFI integrity.

All units can be supplied factory modified with machining and silk screening to the user’s specification. AutoCAD and PDF dimensioned drawings can be downloaded from www.hammondmfg.com/dwg_OctTrap.htm
