Hammond RP1090BF 105x75x55mm Polycarbonate Watertight Flanged Enclosure

The RP1090BF is a water-tight polycarbonate enclosure with an integral bottom flange and a opaque lid, sized 105 x 75 x 55 mm (4.13 in x 2.95 in x 2.17 in). It is aimed at OEM engineers, electronics builders and electricians who need a gasketed housing for printed circuit boards or components that bolts flat to a panel, wall or chassis through its flange. The opaque lid hides the contents and offers a smooth recessed area on top for a membrane, label or silkscreen.

The body is polycarbonate with a flame rating of UL94 V-2, compared with the UL94-HB general-purpose ABS versions in the same series. The part page lists the colour as Light Gray; the series ordering table lists this part under Off White Polycarbonate. A two-piece tongue-and-groove lid with a rubber gasket (included, field installed) guards against oil, dust and water, and the design is rated IP65. Self-captivating M3.5 stainless steel lid screws (included) thread into corrosion-resistant bushings for repeated assembly and disassembly.
