The 1457J1202EBK is an EMI/RFI shielded extruded aluminum enclosure from the 1457-EMI Series, measuring 4.73 in x 3.3 in x 1.12 in (120 mm x 84 mm x 28 mm). It is aimed at design engineers who need to house a PC board in a metal case with conductive seals at the ends to control electromagnetic and radio-frequency interference. The body is black powder coat, while the end panels are black.
The body is a single aluminum extrusion with a minimum wall of 1.5 mm (0.06”), and boards slide horizontally into slots extruded into its sides. Maximum board size is 119 x 79 mm per the part data (120.00 x 80.00 mm in the series table). On the drawing the extrusion is 119.15 mm [4.691 in] long and 86.96 mm [3.424 in] wide, with an inside face-to-face dimension of 120.00 ±0.50 mm.
Each diecast aluminum end panel is painted in black satin powder paint and sealed with a full-perimeter conductive foam/fabric gasket made of Ni/Cu (nickel/copper) with CPSA (conductive pressure sensitive adhesive). The enclosure is rated IP54; the series notes these gaskets are not water-tight. Stainless steel hardware with rubber o-rings, adhesive rubber feet and black zinc plated screws (ASTM B633-13 Type II, SC3) are included; recommended torque is 5 lbf/in.
1457J1202EBK is the flanged version: its end panels carry integrated mounting flanges so the enclosure can be screwed to a wall or chassis. The drawing gives 152.14 mm [5.990 in] overall over the flanges, with flange holes on 140.14 mm [5.517 in] centres. The same enclosure without flanges is 1457J1201EBK.
The drawing specifies the box as 6063 extruded aluminum and the end panels as ADC-12 diecast aluminum, and identifies this EMI/RFI shielded (IP 54) version as black powder painted box and end panels. The purchased assembly includes the box, end panels, #6 Taptight screws with O-rings, self adhesive rubber feet and gaskets.
Shipping weight is 0.5 lbs (0.23 kg), shrink wrapped. The part is RoHS and REACH compliant, and enclosures can be factory modified by milling, drilling or printing.
