The RP1045BFC is a water-tight general-purpose ABS enclosure with an integral bottom flange and a clear lid, measuring 95 x 50 x 50 mm (3.74 in x 1.97 in x 1.97 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 87.70 mm [3.45 in] long, 42.70 mm [1.68 in] wide and 44.50 mm [1.75 in] high, and 119.95 mm [4.72 in] overall length across the flange, which carries 4.20 mm [0.17 in] mounting holes. The part page lists a maximum PC board size of 87 x 41.5 mm, and the internal board posts accept M3 self-tapping screws. This size is the narrowest width (50 mm) in the series ordering table, a long, slim footprint offered in 40 mm and 50 mm heights.
Matching accessories listed for the RP1045BFC include plastic inner panel STC104, aluminum inner panel STA104 and replacement gasket two-pack RP103GASKET.
