The 1455NC1201 is a 120 mm clear anodized extruded aluminum channel mount enclosure, designed to house P.C. boards or equipment and to mount easily to aluminum channel. It is aimed at OEM engineers, panel builders and integrators who want an enclosure that fastens to a channel with T-bolts and T-nuts. The 120 mm length is the shortest in the 1455NC range, which also comes in 160 mm and 220 mm lengths with the same 103 mm x 53.01 mm cross-section.

The body is a rugged one-piece extrusion with a minimum wall thickness of .09" (2.29 mm); the drawing specifies extruded aluminum 6063. This is the open-bezel version: aluminum end plates (drawing outline 95.02 mm x 45.00 mm [3.741 in x 1.772 in], 1.50 mm [0.059 in] thick) sit inside open plastic bezels, and both the extruded body and the end plates are clear anodized. The plastic-end-cap equivalent is 1455NC1202.

Nominal size is 4.72 in x 4.06 in x 2.09 in (120 mm x 103 mm x 53 mm), and the series table gives 120.00 mm long x 103.00 mm wide x 53.01 mm high. P.C. boards mount horizontally by sliding into internal slots in the body. The series sizes the enclosure for boards 92 mm (min) to 98 mm (max) wide and notes it will not accept, and was not designed for, 100 mm wide eurocard; the part listing gives a maximum board size of 119 mm x 99 mm.

The assembly includes extrusion, plastic bezels, end panels, #6 Taptight screws and self adhesive rubber feet, with eight (8) clear zinc-plated assembly screws; recommended screw torque is 5 lbf/in. It is rated IP54, RoHS and REACH compliant, and ships shrink wrapped at 0.8 lbs (0.36 kg). Channel mounting accessories are 1455TBOLT (T-bolt, M8 x 20), 1455TNUT (T-nut, M8), 1455TSNUT (T-nut with spring, M8) and 1455NCFL (flange brackets).
