Product Overview

The HN-45 plastic enclosure offers durable, weather-tight protection for electronic applications. Molded from black or gray polycarbonate with an optional clear cover, it features three surface-mounting variations: molded-on flanges, stainless steel feet, or no external mounting. Install internal components easily using the molded-in PCB bosses, or use the optional internal panel or DIN rail kit (sold separately). Rated up to NEMA 6P and IP68, the HN-45 is ideal for harsh indoor or outdoor environments.
