The RP1240 is a polycarbonate watertight enclosure with an opaque lid from the RP Series of water-tight ABS and polycarbonate enclosures, sized 6.54 in (166 mm) long, 4.96 in (126 mm) wide and 2.95 in (75 mm) deep in the series ordering table. It is intended for panel builders and OEM engineers who want polycarbonate's UL94 V-2 flame rating in a sealed, opaque box for circuit boards and components.
RP1240 is made from polycarbonate with a flame rating of UL94 V-2. The drawing and series ordering table list it as Polycarbonate Off-White with an opaque lid; the part page records the colour attribute as Light Gray. A gasketed lid with two piece tongue and groove construction protects against access of oil, dust and water, and the enclosure is designed to meet IP65. The rubber string gasket is included and must be field installed.
Per drawing RP124, the enclosure measures 165.50 mm [6.52 in] x 125.50 mm [4.94 in] x 75.00 mm [2.95 in] overall, with an inside length of 158.01 mm [6.22 in], inside width of 117.86 mm [4.64 in] and inside height of 68.30 mm [2.69 in]. It accepts a printed circuit board up to 151 x 114 mm, fastened to internal posts that accept M3 self-tapping screws. It is the deeper of the two depths (55 mm and 75 mm) offered on the 166 x 126 mm footprint, leaving more headroom above a board for taller components.
The lid is secured with self-captivating M3.5 stainless steel machine screws threaded into corrosion resistant bushings, so it can be removed and refitted repeatedly; the recommended torque is (43-50) Ozf.in / (30-35) cN.m. A smooth recessed area in the lid (0.40 mm [.02 in] inlay depth) takes a membrane, label or silkscreen. Optional inner panels are STC124 (ABS, 3 mm thick) and STA124 (metal, 1 mm thick), and the replacement gasket two-pack is RP124GASKET.

- Housing printed circuit boards and electronic components
- Wet, dusty or oily locations needing IP65-designed protection
- Enclosing PCB assemblies up to 151 x 114 mm
- Front-panel membranes, labels or silkscreen in the recessed lid
- Designs requiring a UL94 V-2 rated polycarbonate enclosure
