The RP1085BFC is a water-tight general-purpose ABS enclosure with an integral bottom flange and a clear lid, measuring 105 x 75 x 40 mm (4.13 in x 2.95 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 clear lid leaves the board and components inside visible while the lid stays closed.
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.
The drawing gives inside dimensions of 97.93 mm [3.86 in] long, 67.93 mm [2.67 in] wide and 34.30 mm [1.35 in] high, and 134.95 mm [5.31 in] overall length across the flange, which carries 4.68 mm [0.18 in] mounting holes. The part page lists a maximum PC board size of 92 x 62 mm, and the internal board posts accept M3 self-tapping screws. This size is a 105 x 75 mm footprint that the series ordering table offers in 40 mm and 55 mm heights.
