Examples of enclosures with recessed surfaces

WHICH FEATURES ARE CURRENTLY MOST IMPORTANT IN ENCLOSURES FOR EMBEDDED SYSTEMS?

1. IP protection class:

A certain degree of protection against dust and moisture is often required. This means that enclosures with high IP protection classes, such as IP 65 (and in some cases even higher), are in demand. This is achieved by tongue and groove connections between the individual parts and an additional seal that is inserted into the groove and then sealed accordingly during assembly.

However, with standard enclosures, the IP protection rating can only be guaranteed in its original state. Once openings, drill holes, or similar modifications are made, the final device must be retested and, if necessary, certified by the customer.

2. Material:

It is important to use high-quality, single-type, UL-listed plastic materials. Depending on the intended use of the enclosures, they may also need to have higher weather resistance and improved fire protection (e.g. ASA+PC UL94 V-0 for Evotec / Easytec).

3. Mounting options:

There is often a requirement to mount enclosures on walls, pipes, rails, cable trays, or directly onto machinery (for example, equipment used in smart factories). Enclosures that can be screwed directly in place or secured to flat surfaces—such as walls, ceilings, or machines—using separate wall brackets are well-suited to this purpose. In certain cases, magnets may also provide a practical fastening solution for machinery. There are also robust enclosure series (Easytec  / Mini-Data-Box), which can be quickly and easily attached using cable ties or band clamps via external tabs.
