Could you advise the most reliable method for mounting a PCB within enclosures please?

The most important aspect to consider when mounting a printed circuit board (PCB) into an enclosure is preserving the integrity of both the PCB and the enclosure. Failure to do so, e.g. drilling holes into the structures, could compromise the functioning of the PCB or affect the properties of the enclosures, e.g. IP rating, thermal resistance or impact protection. Therefore, pre-designed solutions are to be favoured.

Some manufacturers equip their enclosures with vertical guides within the side walls. However, this solution can result in the cable glands potentially fouling on the PCB once fitted through the side wall. Also, this design will often limit space within the enclosures, possibly blocking the entry for cables and other components.

Through many years’ experience working with electrical designers and installers, Spelsberg has addressed these issues by designing the PCB kit. This is installed in the corners of the enclosure, enabling cable gland entry and preventing any fouling effects.

The kit can be used on our TK range of polycarbonate (PC) and polystyrene (PS) enclosures, and is available in two variants, based on the size and design of the PCB. More precisely, for smaller applications we suggest using TK MLH-55/75, while we recommend using TK DST for larger PCBs and enclosures.

If you’d like more information about mounting PCBs into Spelsberg electrical enclosures or have specific requirements for your intended application, please feel free to send me a private message to discuss the solution that best fits your needs.
