ENCLOSURES Ticking all the boxes W
hile the enclosure might seem a humble component of a control system, for designers correct selection is vital to ensure suitability for the intended application. Nobody knows this more than Lawtronic, a renowned electrical control solutions provider for the past 36 years. We have a long-term relationship with Spelsberg, a market leader in enclosure technology that has supplied a wide range of boxes for Lawtronic projects.
Variety is the spice of life We offer a complete service for control systems in applications across many industries, encompassing design, manufacture, testing and installation. Typically, we use Spelsberg enclosures for our marine, refrigeration, and baggage handling systems amongst others. There are obviously big application differences, so having a wide variety of boxes to choose from is important to us.
exist anymore. Consequently, designers need a wide range of sizes, models, materials and characteristics to choose from to ensure suitability.
While a high ingress protection rating might be an important feature for a marine application, for a baggage handling machine small footprint, having a multitude of sizes to expedites a control system design project. We had one customer who required an enclosure with a transparent lid so that engineers could easily view the electronics meant we could easily meet the customer request with an off-the-shelf item.
Handling customisations Even with varied options, an off-the-shelf control system designer, and one Lawtronic project illustrates this.
for control systems Dave Tester, managing director, Lawtronic, says how his business collaborated with Spelsberg to help overcome modern challenges in control system design and supply
We developed a custom control system concept for a tray return conveyor installed on X-ray security machines destined for an airport in Dubai. A standard enclosure solution of the machine, so we worked with Spelsberg during the design phase to produce one that would, and at the same time would dramatically reduce our labour during build. ensures that enclosure manufacturers can support control system designers early in development with bespoke solutions. CNC machining allows new enclosures to be prototyped quickly, so that the design team Ultimately, an enclosure that exactly matches the unique requirements of the control system is achieved.
Repeatability is a big thing for us too. We typically design control systems for volume production machine builders. For example, the system for the airport was required for over 100 individual machines. Not only do we need custom enclosures, but we sometimes need lots of them.
manufacturers can not only produce custom items on reduced lead times for the development process, but also offer

required to deliver short production runs of unique designs.
Controlling supply chains engineering of control systems, but to supply as well. Across industry, suppliers and manufacturers are looking to localise their logistics operations to improve availability and minimise the effects of delays and increased costs.
“Everyone is working to make supply chains more robust through reshoring, and Spelsberg offering us local availability in the been to hold more stock, and Spelsberg has supported this by providing us with increased enclosure inventory capacity. This gives us a more responsive and resilient supply chain. Local availability ensures that control system manufacturers can insulate supply chains from external shocks. The advantages of increased stockholding and reliable delivery streamline projects and adding value.
