Hammond RM3U0808VBK 3U Half-Width 8" Deep Vented Aluminum Enclosure

The Hammond RM3U0808VBK is a 3U vented rack-mount / desktop instrument enclosure from the RM Series, measuring 5.25 in (133 mm) high, 8.30 in (211 mm) wide and 8.00 in (203 mm) deep. It is built for OEM engineers, test and measurement designers and integrators who need a lightweight, all-aluminum case that can sit on a desktop or bench, or be adapted for rack use with the optional RM3UMTGFL mounting flange.

This half-width build adds a vented top and bottom: the drawing shows a field of Ø4.32 mm [0.170 in] holes in 8 rows and 22 columns, giving convection airflow for warm electronics in a compact 8 in deep case.

Construction uses extruded aluminum side panels and extruded aluminum front and rear panels, each 0.125" (3.2 mm) thick, with flat aluminum top and bottom panels 0.064" (1.6 mm) thick. The drawing specifies a Type 6063 extruded aluminum frame and .064" 5052-H32 aluminum panels. The enclosure is finished in rugged textured black powder coat and uses a knockdown design that ships unassembled for easy handling and shipping protection. Because of the powder coat, panels are not grounded to the frame; the grounding method is determined by the customer.

Per the RM3U0808VBK drawing, the assembly hardware comprises: 12 Screws - Flat Head 4-40 x 3/8"; 8 Screws - Flat Head 6-32 x 3/8"; 12 Nuts - #4 Speed Nuts; 4 Self Adhesive Rubber Feet. It accepts pull handle part number 1427P1BK, sold separately.

The RM3U0808VBK is RoHS and REACH compliant, manufactured in North America, and ships in a box at 6.2 lbs (2.81 kg). Enclosures can be factory modified with milling, drilling or printing, and solid models are available in STEP or IGES for design work.
