The 518-0920 is the larger of the two 518 Series module instrument enclosures. It is 11.75 in wide and 6.25 in tall, giving generous room for instrument electronics, power supplies and front-panel controls in a portable steel case with a carry handle.

An 18 ga. steel base and top (0.05" steel case) keep the front and back panels from pushing in under mounted buttons, controls or connectors. One horizontal row of louvers along the sides provides ventilation, and the case can be reversed for sloping or vertical sides. Eight M4 machine screws thread into internal weld-nuts, making the case suited to repetitive assembly and disassembly. It is supplied pre-assembled in two tone grey powder coat, with a dark satin grey top and a smooth light grey bottom, front and back.

Dimensions: width 11.75 in (298 mm), top length 9.63 in (245 mm), bottom length 7.75 in (197 mm), height 6.25 in (159 mm). The drawing shows an overall width of 313.21 mm [12.33 in] and overall height of 159.74 mm [6.29 in]. Rated IP30 and RoHS and REACH compliant, it ships at 6.39 lbs (2.90 kg).

The 518-0920 includes the 1427C1 handle kit with top mounting holes, two plastic plugs for use without the handle, four self-adhesive rubber feet and required hardware.
