PN-1337 is a NEMA 4X sealed enclosure designed to protect electrical and electronic equipment in harsh outdoor and corrosive environments. The enclosure is available in polycarbonate (light gray or clear) or high-impact ABS (dark gray) construction, with UV stabilization for extended outdoor durability. The polycarbonate variant carries a UL94-HB flammability rating and operates across a service temperature range of -40°C to +120°C, while the ABS variant is rated for -40°C to +80°C. The enclosure features a silicone gasket for sealed protection, four mounting bosses accepting M2.5 metric or #4 sheet metal screws, and includes a hardware kit with M4 × 20 mm screws for assembly. Its compact dimensions and robust construction make it ideal for outdoor control panels, telecommunications equipment, and industrial automation applications requiring IP66/IP67-equivalent environmental sealing.
