The 1457J1201E 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 clear anodized, 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 assembly is 131.15 mm [5.163 in] long overall and 86.96 mm [3.424 in] wide, with an inside face-to-face dimension of 120.00 ±0.50 mm, and it fits a 120mm (4.724") X 80mm (3.149") PCB.
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.
1457J1201E has flat end panels without flanges and stands on the adhesive rubber feet supplied with the hardware. Where wall mounting is needed, choose 1457J1202E, which has integrated flanges, or fit the 1457JEPF flanged EMI end panel kit.
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 a clear anodized box with black powder painted 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 0.2 lbs (0.09 kg), shrink wrapped. The part is RoHS and REACH compliant, and enclosures can be factory modified by milling, drilling or printing.
