means of Control Cockpit software that provides comprehensive control and monitoring functions with the flexibility to add, remove, report and create an alarm in support of the SYSLOG standard – plus an SNMP interface for integration with third party systems. However, while this high-end security has been developing, the more mundane security issues of industrial electrical and electronic control and supply cabinets have not been ignored – such that we now have mechanical solutions such as interchangeable lock cylinders that can be removed and replaced at any point in the installation process. ‘Everything but the enclosure’ technologies have a long lifecycle and there is much from 1995 which is still perfectly suitable, but elsewhere we have seen refined engineering capability for standard and custom products including friction welding, sintered metal production and 3D CAD modelling, a process which has not only enabled development of more complex designs, but also put the panel engineer in direct contact with the product designer via detailed downloadable drawings. Much too has changed in the
small things – often overlooked – we can now source pre-cut, pre-assembled and vulcanised gasket, installation-ready

without messy cutting and gluing. EMC gaskets have become mainstream, while a major demand has been identified for fire protection and high temperature gaskets in EPDM and silicone. Previously, assembling rod
locks took many minutes, now advances in design and plastics technology mean that rod guides can be fitted in seconds while precision plastic mechanisms provide quiet operation and more comfortable feel than older style units made from die castings or metal stampings. Rod systems not only improved, they moved. At one time only installed inside the gasket area, rod lock systems migrated beyond the gasket, at the same time freeing up door areas and enabling simpler sealing arrangements for locks. Growth in technology and sophistication of design has been matched with commercial developments that support specialist enclosure and panel builders. Toggle latches continue to find new application, torque and friction hinges have become mainstream, rather than just something to be used on expensive electronic devices, and in response to globalisation we have also seen also an expansion of UL certification.
