The 1550Z120 is a diecast aluminum enclosure designed for NEMA 4 and 4X rated applications, providing robust protection for electronic components and instrumentation. The enclosure features internal dimensions of 163.14 mm (6.42 inches) length, 93.78 mm (3.69 inches) width, and 49.90 mm (1.96 inches) depth, with an average wall thickness of 3.00 mm (0.12 inches). The assembly includes a box, lid, silicone gasket, and 4 cover screws, with mounting provisions for M4-0.7 machine screws and #6 self-tapping ground screws. The enclosure is constructed from diecast aluminum alloy and is UL listed, making it suitable for industrial control, telecommunications, and outdoor applications requiring corrosion resistance and environmental sealing. Screws should be torqued to 5-7.5 lbf·in (50-75 cNm) for optimal performance and seal integrity.
