A multi-portion housing for a portable terminal having a proximal end, a distal end, a bottom surface, and a top surface, the top surface configured for mounting a user interface between the proximal and distal ends. The multi-portion housing comprises a central housing portion providing a rigid body extending between the proximal and distal ends for facilitating rigidity of the multi-portion housing to inhibit deformation of the multi-portion housing, the central housing portion having an upper surface and an opposing lower surface. A second housing portion is secured to the central housing portion and has a first resilient seal positioned between a first mating surface of the second housing portion and a corresponding mating surface of the central housing portion, the corresponding mating surface of the central housing portion extending only partway between the proximal and distal ends and being positioned on either the upper or the lower surface. A third housing portion (e.g. an endcap) is secured to the second housing portion and has a second resilient seal positioned between a second mating surface of the second housing portion and a corresponding mating surface of the third housing portion. The first resilient seal and the second resilient seal are configured for inhibiting penetration of foreign contaminants into an interior of the multi-portion housing.
