The R100-104-000 is the longest 100 mm wide size in Hammond's R100 Series of Type 4X diecast aluminum enclosures (aluNORM - Watertight, Thick Wall), finished in RAL 7032 beige. It is built for panel builders, OEM engineers and electricians who need a rugged, sealed housing for a P.C. board up to 186.9 mm x 87 mm.

The R100-104-000 measures 3.94 in x 7.87 in x 3.15 in (100 mm x 200 mm x 80 mm), matching the ordering table's 100 mm width, 200 mm length and 80 mm depth with lid. It accepts a maximum P.C. board of 186.9 mm x 87 mm. Shipping weight is 2 lbs (0.91 kg).

The body is die-cast aluminum to G AI SI 12 / DIN 1775 in a thick-wall, shallow lid and deep body design, coated in textured polyester powder. A standard neoprene gasket resists oil and petrol, and the enclosure is rated IP66, CSA certified and UL Listed Type 4 for use with industrial control equipment, with an operating temperature range of -40ºC to +80ºC (-40ºF to 176ºF). Its part page lists NEMA ratings 1, 4, 4X, 12 and 13.

Hammond's patented single-channel system uses the same threaded enclosure hole both to mount the enclosure and to fasten the lid, keeping lid screws and mounting holes outside the gasket seal and giving more interior space than dual-channel designs. The lid screws are captive stainless steel, and internal mounting shelves along both sides carry blind holes and grounding screws. All three accessories are listed: R501-002-100 external feet, the R507-104-000 inner panel and the R510-000-000 hinge set.

The same size is also offered in RAL 7035 light gray as R100-104-035. The R100-104-000 is RoHS and REACH compliant.
