Know-how about the tightness of mechatronic housings
I give you the knowledge to optimally design the tightness of your mechatronic housings. I am available to contact you at any time.
Functions of a housing
The housing of a circuit board has to fulfill many different functions. On the one hand, it protects the circuit board from adverse effects such as water and cleaning agents as well as dust and dirt. The demands on the tightness of a housing are correspondingly high.
There are various levels of tightness that have been developed for different purposes.
Standards such as DIN EN 60529 specify tightness in so-called IP protection classes. The higher the tightness requirements, the more expensive the housing becomes. It is therefore important that your electronics designer checks in advance what level of tightness is required. The sealing material should also be selected with the greatest care. In this way, costs can be saved in the long term.
Requirements for a housing seal
A housing must meet various requirements. To do this, the housing and seal construction must be coordinated with one another.
The seal reliably protects the electronics from disruptive environmental influences such as oil and cleaning agents (acid and alkali). To do this, the sealing material must be selected to suit the operating conditions. Therefore, influences such as UV and ozone radiation as well as high and low temperatures must be taken into account when selecting the material.
In order to meet these requirements, different types of seals exist.
These range from O-rings to flat seals and molded seals. The types of seals also include adhesive seals and metering seals (so-called FIGP system, Formed In Place Gasket). What they all have in common is that the seal geometry must be carefully designed. Compression and compression set must be precisely coordinated in order to be used in the main force or in the shunt.
