Fischer Elektronik has extended its range of tube cases, with specially shaped tube profiles to install front foils and membrane keyboards. The tube cases have integral guide slots to accommodate non-standard PCBs. The standard version of the case is available in five lengths (100, 120, 160, 200, 220mm) and three surface finishes. An EMC-compatible version using electrically conductive transparent passivated surfaces and additonal conductive seals is also available. By using special seals protective class IP54 can be achieved. In addition to the standard versions all cases can be machined, surface-treated and printed to suit specific requirements. The tube cases are supplied unassembled and include cover panels and installation materials.
