The RP1050C is a polycarbonate water-tight enclosure with a clear lid, part of the RP Series. It is a near-square, low-profile box sized for compact square-format circuit boards; the transparent lid makes it well suited to builds where the contents need to stay visible, for OEM engineers, integrators and electronics builders mounting printed circuit boards or components.

Polycarbonate gives this model a UL94 V-2 flame rating (the drawing lists it as Polycarbonate Off-White with Clear Lid, UL94-V2). A two piece tongue & groove lid with a field-installed rubber gasket is designed to meet IP65, protecting against oil, dust and water.

Nominal size is 3.35 in x 3.15 in x 1.57 in (85 x 80 x 40 mm); the series ordering table lists it as 3.43 in (87 mm) x 3.23 in (82 mm) x 1.57 in (40 mm), and the drawing shows 86.50 mm [3.41 in] x 81.50 mm [3.21 in] x 40.00 mm [1.57 in] overall. Inside, the drawing gives 34.50 mm [1.36 in] of height and 74.12 mm [2.92 in] of width, 79.22 mm [3.12 in] inside length, and the 40 mm depth keeps the enclosure low-profile. PC board mounting posts accept M3 self-tapping screws and take a board up to 77 mm long and 72 mm wide.

The lid is secured with M3.5-0.6 x 10mm self-captivating screws threaded into corrosion resistant bushings for repeated assembly and disassembly; recommended torque is 43-50 ozf.in (30-35 cN.m). Each RP1050C ships in a bag with the box, lid, string gasket, 4 PCB screws and 4 lid screws. Optional inner panels are STC106 (ABS, 3mm) and STA106 (metal, 1mm), and RP106GASKET is the replacement EPDM gasket 2-pack. The part is RoHS and REACH compliant.
