In the world of panel building, there is often the requirement for a low cost, compact enclosure that can be easily fitted – sometimes during the latter stages of manufacturing to accommodate design modifications - to house a small circuit board or similar electronic assembly. Available from Switchtec, Euroclamp’s CEM series modular DIN rail enclosures provide just the solution.
Aimed at OEMs, equipment and component manufacturers, sub-contractors, and distributors the important application areas for the enclosures include lighting controllers, circuit protection, energy management systems, power supplies, and HVAC controls. Driving the demand for this type of product is the need for an off the shelf, DIN mounted PCB enclosure that is robust and ‘customisable’ to meet the increasing use and deployment of electronic assemblies and small ‘add-on’ electronic networks in control panels.
Available in three sizes, 17.5, 22, and 35mm, the enclosures are supplied as three sub components; the main body, the top cover and the bottom mount that is furnished with two DIN rail clips, enabling quick and easy installation and removal from DIN rails. As such the enclosures are designed and manufactured to be a ‘snap-fit’, tool-less product. The two larger sized units (CEM-22 & CEM-35) are available in vertical and horizontal versions. This denomination relates to the orientation of the PCB mounted inside the enclosure. As appropriate, the two versions allow two PCBs to be mounted inside either vertically or horizontally, providing the user with maximum flexibility from a standard DIN enclosure.
Bringing versatility to the range, accessories for the CEM series include a clear top cover, and a TP35 blanking or vented insert that enables easy modification of the enclosure to accommodate different components. But the ace card in the CEM series’ armoury is the ML25 series terminal block. This range has been designed specifically for use in the CEM enclosures, and as such provides the perfect finish to the assembled product. The ML25 terminals are available in two and three way vertical and horizontal types and with left and right ‘dog leg’ pins to optimise positioning and accessibility. Also available is the specially modified PVXX-5-LS/LD plug in PCB header with dog leg pins, again designed specifically to serve the CEM series. This product allows the use of plug in terminals on certain models in the CEM series.
Manufactured from flame retardant UL94V0 material, the enclosures come in a standard light grey (RAL7035), but can also be supplied in black, green, red or blue to order to match customers’ needs and colour schemes. Further, enclosures can also be manufactured to customers’ specifications. Holes can be provided for component access, terminals can be blanked and the body can be screen printed to the customer’s design.
The CEM Series from Euroclamp is manufactured to a genuinely high specification, including internal PCB supports and guides, ensuring that PCBs are held firmly in place, which is of great importance when mounting PCBs that are populated with heavier components such as relays or transformers.
Compared to the competition, the Euroclamp CEM series is more flexible with its three sizes - with matching profiles – its accessories manufactured from the same plastic as the enclosure, and its customised options, the result being a highly desirable product for panel builders.
