The RP1025BF is a water-tight general-purpose ABS enclosure with an integral bottom flange and a opaque lid, measuring 65 x 60 x 40 mm (2.56 in x 2.36 in x 1.57 in). It suits electronics builders, OEM engineers and electricians who want a general-purpose gasketed housing for printed circuit boards or components, fixed down through its flange. The opaque lid includes a smooth recessed area for a membrane, label or silkscreen.
It is moulded in light gray ABS plastic with a flame rating of UL94 HB; the series also offers polycarbonate (UL94-V2) versions of the same size. 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.
