Enclosures Pixus Offers Modular Subracks for Mounting of 3U, 6U and Custom Sized Boards Pixus Technologies, a provider of embedded computing and enclosure solutions, now offers modular subracks and components for plugging of various sized boards. The subracks are commonly 3U and 6U high or 4U and 7U allowing for spacing for fans. The modular subracks from Pixus come in 84HP (for 19 inch rackmount size), 42HP, and 21HP widths. The extruded rails feature tapped holes and optional extensions for IEEE injector/ejector latches. Multiple depth options are available and EMC versions are also standard. Components in the Pixus subracks standardly have a clear chromate finish and are made of lightweight aluminum. Pixus offers ruggedized versions of its subracks and rail components. The rugged Mobile line of subracks has shown proven reliability in German railway applications for decades. The company also offers double rails for extra strength and rigidity. Extended Length 1590 Die-Cast Enclosures Developed to Suit Two Very Different Requirements The 1590 die-cast enclosures family from Hammond Manufacturing consists of 41 different sizes in the standard rectangular, and STOMP Box, painted variants. STOMP boxes, color coded to provide visual quick identification on stage are the housings of choice for leading stomp box manufacturers. Also known as guitar effect pedals, they are the housings for foot-operated equipment used by electric guitarists to produce preset effects such as distortion, wah-wah, delay, chorus and phaser. Two new sizes, the 1590 BX2, 10 by 2.8 by 1.4 inches (254 by 70 by 35 mm) and 1590 BX, 10 by 2.8 by 2.0 inches (254 by 70 by 51 mm), have been added to the range to allow multiple pedals to be mounted in a single enclosure. The two new sizes have also been specified in a completely different requirement, a radio antenna splitter, where multiple local feeds are broken out from the incoming aerial. In both applications, the intrinsic RFI shielding, the mechanical strength and the environmental sealing of the 1590 were important requirements. 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. The 1590 is available as standard in natural finish or with a satin black painted finish. Passively Cooled Instrument Shelters Intertec is exhibiting an innovative approach to housing remote instrumentation and communications equipment in harsh environments, in the form of a passively cooled walk-in shelter. The shelter can greatly reduce the problems of installing equipment in remote locations, where reliable power is unavailable, and where dust and sand in the atmosphere can make it difficult to cool electronics equipment using conventional air conditioning systems. Another major element of the shelter's performance is its construction from GRP (glass reinforced polyester) panels employing a composite 'sandwich' construction to provide a very high degree of insulation, plus surface protection that can survive the extreme challenges of the Middle East environment, including very high levels of UV and dust and sand abrasion. GRP is an inherently inert material that is virtually immune to corrosion and atmospheric pollutants. It is also resistant to a wide range of petrochemical media. Intertec's shelter employs a highly efficient passive cooling system that exploits the energy storage capacity of water, which circulates by natural convection. This passive, unpowered system can be boosted by a small externally mounted electrical cooler driven by solar panels, to optimize performance on hot sunny days. Using this and other hybrid techniques, Intertec is able to provide passively-cooled shelter solutions that are able to operate in equatorial regions, as well as the arid climates in which they are widely used today. 22 Fall 2016 * www.ElectronicsProtectionMagazine.com http://www.ElectronicsProtectionMagazine.com
