Hammond 1457N1201EBK 120mm EMI/RFI Shielded Aluminum Enclosure, Black

The 1457N1201EBK is a 120 mm long, 55 mm tall EMI/RFI shielded enclosure from the 1457-EMI Series, built on a 104 mm wide aluminum extrusion and closed with flat end panels (no mounting flanges). At 55 mm it is the taller of the two 104 mm wide profiles in the series, intended to house a shielded Eurocard-format PC board or to serve as an equipment-interfacing enclosure.

The body is one piece of extruded aluminum 6063 with a minimum thickness of 0.06" (1.5 mm) and a 0.75 mm (0.030") deep recess for a label or membrane keypad. The extruded body is finished in black powder coat, and the two Type 380 diecast aluminum end panels are painted in a durable black satin powder paint, giving an all-black exterior. Full perimeter conductive foam/fabric gaskets of Ni/Cu (nickel/copper) with conductive pressure sensitive adhesive seal each end panel to the body.

Nominal size is 4.73 in x 4.09 in x 2.15 in (120 mm x 104 mm x 55 mm), with an inside face-to-face dimension of 120.00 ±0.50 mm [4.724 ±0.020 in]. PC boards slide horizontally into internal slots extruded into the body; part data lists a maximum board of 119 mm x 99 mm, and the drawing notes "Fits 120mm (4.724") X 100mm (3.937") PCB". Shipping weight is 0.69 lbs (0.31 kg).

Flat end panels keep the footprint to 132.15 mm [5.203 in] over the panels (drawing), and adhesive rubber feet are included for bench or shelf use. A version with wall-mounting flanges is available as 1457N1202EBK. Assembly uses #6 Taptight thread forming screws with O-rings, black zinc plated to ASTM B633-13 (Type II, SC3); the recommended screw torque is 5 lbf/in.

The enclosure is designed to meet IP54 and is RoHS and REACH compliant. Note that the EMI gaskets are not water-tight. Solid models are available in STEP or IGES, and the factory can mill, drill or print the enclosure.
