stainless steel screws, and an impact resistance of up to 7 joules (IEC 60079-0:2004), these cases are suitable for safely enclosing electronic components, PCBs or e-mech components such as relays and switches. Available in 6 sizes and withstanding temperatures ranging from -60 C to +200 C in areas that are generally considered too harsh for other enclosure materials. They can be punched with holes and slots to your exact
Corrosion-resistant flexible
diameter. The maintenance-free and corrosion-resistant housing made of polypropylene have a maximum utilized terminal space, which makes the installation particularly simple.
The cables are inserted directly through the existing
openings without a clamping nut, since the integrated diaphragms allow flexible cable routing. JB – junction boxes are available in two sizes of 90 x 90 x 49mm or 110 x 110 x 49mm and feature a snap-on cover which can easily be securely attached without screws in all versions. With Ip65 protection, the degree of impact strength IK 04 and a temperature range o f-5 ° C to 60 ° C make the housings suitable for both indoor and outdoor applications.

How to Check if Cooling Output inside Enclosures is Sufficient
M
anufacturing automation systems are delicate and very expensive
pieces of kit, which perform vital functions for the businesses they serve. The enclosures that protect them
must have strictly controlled internal environments with interior temperatures that are carefully maintained within a few degrees. If not, the impact can be harmful to the inverter drives, power supplies, contactors, PLCs and other electrical and electronic components operating within them. This requires careful control of the climate within the enclosure. Here, Jason Swann, Rittal Product
Manager for Climate offers some practical tips on how to evaluate an existing enclosure climate control through a series of simple checks. Like all electrical equipment, drives create heat and they therefore have a major influence on the temperatures
inside enclosures. Drives are often quoted as having efficiency of 97 per cent, so one with a rated output of 150kW can produce as much as 4.5kW of heat. As well as the heat loss inside the enclosure, ambient temperatures within a production facility will also have an
impact on the temperatures that a drive is operating within. A typical enclosure climate control system is designed for an internal enclosure temperature of 35°C. This means that the performance of a cooling unit should be specified so that the average internal enclosure temperature of 35°C can be guaranteed under all load conditions and under all the ambient conditions that could be met at the machine’s location.
These three simple checks are a good starting point:
• Checking the enclosure temperature • Checking the control behaviour of cooling devices • Locating hotspots

Stuart Takes the Helm of Ellis’ UK Sales T
he world’s leading cable cleat manufacturer, Ellis has appointed Stuart Helm as its new national sales manager. Stuart, who previously worked
as product sales manager for Deep Sea Electronics, will work under Ellis’ global sales director, Tony Conroy and will take responsibility for Ellis’ UK sales presence. The role includes identifying and developing new sales opportunities, and working with the North Yorkshire company’s existing customer base. Commenting on his new position, Stuart said: “Ellis has a well-deserved,
strong reputation in the marketplace and has worked on some of the most prestigious, yet challenging power and infrastructure projects worldwide. As the market leader in this field, it was an easy decision to make when offered the position of national sales manager.” Ellis’ UK sales currently account for 50 per cent of the company’s annual £7-million turnover.
