The 1457NEG-10 is a 10-pack of EMI/RFI replacement gaskets for 1457-EMI Series shielded enclosures whose part number begins with 1457N. Maintenance teams and OEM builders use them to restore the conductive seal between the diecast end panels and the extruded aluminum body after an enclosure has been opened, reworked or re-machined.
In the 1457-EMI Series the end panel gaskets are full perimeter conductive foam/fabric made of Ni/Cu (nickel/copper) with CPSA (conductive pressure sensitive adhesive), so they adhere to the panel and form a continuous conductive path around its edge. The spec sheet notes these EMI gaskets are not water-tight; if a sealed end is the priority, the water-tight gasket for the same enclosure is 1457NPG-10.
Per the drawing, each gasket measures 104.00 mm [4.094 in] wide by 54.60 mm [2.150 in] high and 1.57 mm [0.062 in] thick, with four Ø2.50 mm [Ø0.098 in] holes and R4.00 mm corners, matching the 1457N end profile. Shipping weight is listed as 0.01 lbs (0.00 kg).
The 1457NEG-10 is RoHS and REACH compliant. For a full rebuild, complete end panel and gasket kits are also listed for 1457N enclosures as 1457NEP and 1457NEPF.
