Hammond R100-320-000 320x320x120 mm IP66 Diecast Aluminum Enclosure, Beige

The R100-320-000 is a extra-large, square watertight enclosure from the R100 Series of Type 4X diecast aluminum enclosures (aluNORM - Watertight, Thick Wall). It is the shallow-lid, deep-body version, finished in beige (RAL7032) textured polyester powder coat, and is intended for OEM engineers, panel builders and electricians who need a sealed metal housing for the largest control assemblies the series is built for. The same size is offered in light gray (RAL7035) as R100-320-035.

The body and lid are die-cast aluminum (G AI SI 12 / DIN 1775) with a thick-wall, water-tight design. A neoprene gasket that is oil and petrol resistant comes standard and the stainless steel lid screws are captive. Because of the patented single-channel system, the lid screws and the mounting holes sit outside the gasket seal, and the same channel is used both for mounting the enclosure and for the lid screws, giving more interior space than dual-channel enclosures.

Overall size with lid is 320 x 320 x 120 mm (width x length x depth), listed on the part page as 12.6 in x 12.6 in x 4.72 in (320 mm x 320 mm x 120 mm). Its 320 mm square footprint suits controls and electronics laid out evenly in both directions, and the maximum printed circuit board size is 303 mm long by 303 mm wide. Internal mounting shelves along both sides include blind holes and grounding screws, enclosure holes are threaded for easy installation and disassembly, and the shipping weight is 11 lbs (4.99 kg).

The R100-320-000 is rated IP66, CSA certified and UL Listed Type 4 for use with industrial control equipment, carries NEMA ratings of 1, 4, 4X, 12 & 13, operates from -40ºC up to +80ºC (-40ºF to 176ºF), and is RoHS and REACH compliant. Matching accessories for this size listed by the manufacturer:

• Inner mounting panel, 2 mm galvanized steel: R507-320-000
• Hinge kit (set of 2): R510-000-000

The manufacturer's accessory table lists no external mounting feet for the 320 mm width; mount it through the single-channel holes instead.
