The RP1210BFC is a water-tight polycarbonate enclosure from the RP Series With Bottom Flange, built with a clear lid and an integral bottom flange for surface mounting. It suits OEM engineers and integrators housing printed circuit boards or components, and is designed to meet IP65.

It is moulded in polycarbonate with a flame rating of UL94 V-2. The series ordering table lists this part as the off-white polycarbonate version, while the part page gives the colour as Light Gray. The gasketed lid uses two-piece "tongue & groove" construction to protect against access of oil, dust and water; the rubber gasket is included and must be field installed. The lid is secured with self-captivating M3.5 stainless steel machine screws (included) threaded into corrosion-resistant bushings, and it has a smooth recessed area (0.40 mm [0.02 in] inlay depth on the drawing) for a membrane, label or silkscreen.

This 145 x 105 mm body is the taller of its footprint, with 59.50 mm of inside height for stacked boards, connectors or small DIN-rail devices. Per the drawing, the inside dimensions are 137.74 mm [5.42 in] long, 97.73 mm [3.85 in] wide and 59.50 mm [2.34 in] high, the overall length across the flange is 174.95 mm [6.89 in], and the flange mounting holes are 5.20 mm [0.20 in] in diameter.
