Abstract
A protective device for holding an apparatus having an interaction field is formed from a dimensionally stable protective housing having a lower housing part and an upper housing part. The lower housing part and the upper housing part are releasably connected with one another and an inside contour of the protective housing is adapted and constructed to closely receive the apparatus. The protective housing may be watertight and is provided with a flexible operating area to enable an interaction field to be viewed and manipulated. The operating area may be integral with the rest of the protective housing. Seals are provided between the apparatus and the upper and/or lower housing part and possibly also between the upper and/or lower housing parts themselves. The seals may be formed of a sealing lip or O-ring mating with a circumferential groove. The protective device may also include sealed feedthroughs for connectors, such as cables and external sensors.
