The R251-100-200 is the two-piece "clam shell" body from the R250 Series mobilCASE family of extruded aluminum enclosures. It is designed to house P.C. boards (not included) or equipment for mobile use, giving OEM engineers and integrators a ready-made aluminum housing for portable electronic equipment. This size is 200 mm long, 138 mm wide and has a 100 mm profile width.

Internally, the extrusion is sized for standard Eurocards: P.C. boards mount horizontally by sliding into slots extruded into the enclosure body, and the series lists an internal height of 1.06" (27 mm). This is the two-piece version; the one-piece closed equivalent of this size is R250-100-200. The body is made of aluminum with a modern, ergonomic profile, and the part data lists the colour as Clear (Anodize).

Overall size is 7.87 in x 5.43 in x 3.94 in (200 mm x 138 mm x 100 mm), and the shipping weight is 0.5 lbs (0.23 kg). If you need a shorter case with the same 138 mm width and 100 mm profile, R251-100-160 is the 160 mm version.

End plates are ordered separately. For the two-piece 100 profile the series table lists flat cover plates R586-100-000 (the manufacturer part page for that number directs buyers to use R580-100-000), and the heavy duty diecast end plates are painted textured black (RAL 9005) and come with thermoplastic black gaskets and mounting hardware. With gasketed end plates, the two-piece version is rated to IP 54. Add the R583-100-000 shoulder strap and protective caps for use in rough surroundings, indoors or out, or join this body to a second extrusion side by side with variable cover plates such as R588-080-100, R588-100-100, R588-100-130.

The R251-100-200 is RoHS and REACH compliant and ships in a box.
