Hammond RP1090C 105x75x55mm IP65 Polycarbonate Enclosure, Clear Lid

The RP1090C is a polycarbonate water-tight enclosure with a clear lid, part of the RP Series. It is the 55 mm deep version of the 105 x 75 mm footprint, for boards carrying taller components; 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 4.13 in x 2.95 in x 2.17 in (105 x 75 x 55 mm). Inside, the drawing gives 49.30 mm [1.94 in] of height and 67.40 mm [2.65 in] of width, and the 55 mm depth adds 15 mm over the 40 mm deep model on the same footprint. PC board mounting posts accept M3 self-tapping screws and take a board up to 92 mm long and 62 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 RP1090C ships in a bag with the box, lid, string gasket, 4 PCB screws and 4 lid screws. Optional inner panels are STC109 (ABS, 3mm) and STA109 (metal, 1mm), and RP108GASKET is the replacement EPDM gasket 2-pack. The part is RoHS and REACH compliant.
