The 1457L1201E is a 104 mm-wide, 32 mm-high EMI/RFI shielded enclosure from the 1457-EMI series, built on a 120 mm extruded aluminum body and specified at 4.73 in x 4.09 in x 1.26 in (120 mm x 104 mm x 32 mm). It suits OEM engineers and integrators housing a PC board or interface electronics in a shielded metal case. This version pairs a clear anodized extrusion with flat end panels (no mounting flanges).

The body is one piece of extruded aluminum 6063 with a minimum wall thickness of 0.06" (1.5 mm), and the end panels are easy-to-machine ADC-12 die-cast aluminum. The extruded body carries a clear anodized finish, while the die-cast end panels are painted in a durable black satin powder paint for a two-tone look. Each end panel is sealed with a full-perimeter conductive foam/fabric gasket made of Ni/Cu (nickel/copper) with CPSA (conductive pressure sensitive adhesive), and the assembly is rated IP54. A 0.75 mm (.030") deep recess on the body accepts a label or membrane keypad.

Boards slide horizontally into slots extruded into the body; the series table lists a maximum PCB of 120 x 100 mm, and the part data gives a maximum board of 119 x 99 mm. The drawing shows an inside face-to-face dimension of 120.00 ±0.20 mm [4.724 ±0.008 in], an internal section of 101.00 ±0.75 mm [3.976 ±0.030 in] wide by 27.50 ±0.60 mm [1.083 ±0.024 in] high, and an overall length of 131.15 mm [5.163 in]. The 104 mm-wide L body takes a 100 mm-wide board.

The 1457L1201E ships as a complete assembly: body, two end panels, two adhesive conductive end plate gaskets, #6 Taptight thread-forming screws with rubber O-rings, and self-adhesive rubber feet. The screws are black zinc plated to ASTM B633-13 (Type II, SC3), and the recommended screw torque is 5 lbf/in. If wall mounting is needed, the flanged equivalent is 1457L1202E; this part uses plain flat end panels. The part is RoHS and REACH compliant.
