The Hammond 1457U2801E is an EMI/RFI shielded extruded aluminum enclosure from the 1457-EMI Series, built to house PC boards or interface electronics that need a conductive, shielded case. It measures 280 mm long x 191 mm wide x 68 mm high (11.02 x 7.52 x 2.68 in) and is sized for standard Eurocards, with boards sliding horizontally into slots extruded into the body. The drawing states it fits a 280 mm x 186 mm PCB; the part data lists a maximum board size of 279 x 185 mm.
The extruded body has a clear anodize finish. The body is one piece of extruded aluminum with a minimum wall thickness of 0.06 in (1.5 mm) and a recessed area for a label or membrane keypad. The end panels are diecast aluminum painted in black satin powder paint and are easy to machine for connectors, switches and cable entries. Full-perimeter conductive foam/fabric gaskets of Ni/Cu with conductive pressure sensitive adhesive (CPSA) seal the ends electrically, and the assembly is designed to meet IP54.
This is the non-flanged version: the two diecast aluminum end panels are flat, giving an overall assembled length of 291.15 mm [11.463 in] on the drawing, for applications where no mounting flanges are wanted. Choose 1457U2802E if you need the same 280 mm body with integrated wall-mounting flanges.
Each 1457U2801E includes the extruded body, two end panels, two adhesive conductive end plate gaskets, and stainless steel assembly hardware with a rubber o-ring and adhesive rubber feet. The thread forming screws are black zinc plated to ASTM B633-13 (Type II, 96 hour salt spray; SC3 severe, 12 micron coating); recommended screw torque is 5 lbf/in. Spare end panels (1457UEP 2-pack, 1457UEP-10 10-pack), gaskets (1457UEG-10 EMI, 1457UPG-10 water-tight) and 100-packs of screws (1457MS100) are sold separately. The part is RoHS and REACH compliant and ships at 1.6 lbs (0.73 kg).
