The RP1050BFC is a water-tight polycarbonate enclosure with an integral bottom flange and a clear lid, sized 85 x 80 x 40 mm (3.35 in x 3.15 in x 1.57 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 clear lid leaves the board and components inside visible while the lid stays closed.
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.
The drawing gives inside dimensions of 79.22 mm [3.12 in] long, 74.22 mm [2.92 in] wide and 34.50 mm [1.36 in] high, and 114.95 mm [4.53 in] overall length across the flange, which carries 5.00 mm [0.20 in] mounting holes. The part page lists a maximum PC board size of 77 x 72 mm, and the internal board posts accept M3 self-tapping screws. This size is a near-square 85 x 80 mm footprint which the series ordering table offers in 40 mm and 55 mm heights.
Matching accessories listed for the RP1050BFC include plastic inner panel STC106, aluminum inner panel STA106 and replacement gasket two-pack RP106GASKET. Spare lid screws (SC619-50) and PC board screws (SC622-50) come in 50-packs. It is RoHS and REACH compliant, packed in a bag at a shipping weight of 0.22 lbs (0.10 kg).
