The 1455KHD1601BK is a black-anodized, heat dissipating extruded aluminum enclosure from the 1455HD series. The 1455KHD body has cooling fins along its length and two removable wall-mounting flanges, so it suits OEM engineers and integrators who need to house P.C. boards or equipment that give off heat, on a wall or on a shelf. The manufacturer lists it as a 160 mm finned enclosure.

The enclosure measures 6.3 in x 3.39 in x 2.01 in (160 mm x 86 mm x 51 mm). The series ordering table gives 160.00 mm long, 86.02 mm wide and 51.02 mm high, and the drawing shows a length tolerance of 160.00 ±0.50 mm [6.299 ±0.020 in]. P.C. boards slide horizontally into slots extruded into the body. The extrusion is designed for a 75 mm wide PC board, and the part lists a maximum P.C. board size of 159 mm long by 74 mm wide.

The body and end plates are extruded aluminum (6063 per the drawing) with a black anodized finish. The body is in two pieces: a belly plate removes easily for access to the top of the interior. The assembly includes the box, aluminum end panels, #6 Taptight screws and mounting flanges. Eight black assembly screws match the panels and body; the recommended screw torque is 5 lbf.in (56.5 cN.m). Each end plate has 4 x Ø3.50 mm through holes, countersunk Ø5.75 mm x 90°. The enclosure is rated IP54.

The spec sheet includes a thermal transfer coefficient (°C/W) vs. enclosure length chart for the 1455KHD profile. Values apply to vertical mounting with natural convection, and horizontal mounting adds 15% to the °C/W value. Hammond notes that thermal performance also depends on mounting position, temperature and air velocity.

Hammond can factory-modify these enclosures (milling, drilling, printing) and offers STEP and IGES solid models. Replacement end panels come as 1455KALBK-10 (10 pack), replacement screws as 1455MS100BK (quantity 100), and the clear version is 1455KHD1601. The 1455KHD1601BK ships shrink-wrapped at 0.84 lbs (0.38 kg).
