Eaton Specification Sheet - EIH23 MF
Copper-free aluminum construction delivers corrosion resistance and lighter weight, reducing total lifecycle cost while enabling long service life in chemical and outdoor environments. This material choice lowers maintenance cycles and mitigates potential contamination, supporting safer instrument housing in oil and gas and mining applications. The glass cover provides clear, immediate visibility of instrument indicators without sacrificing environmental protection, improving diagnostic speed and reducing field service time. The 4 in cover opening and 3/4 in trade size sizing fits a broad range of sensors and meters, simplifying procurement and installation while enabling standardized configurations across a multi-site rollout. Cast mounting feet offer stable installation on walls or panels, enhancing vibration resistance and minimizing mounting hardware requirements. With certified ratings for hazardous locations and broad NEMA coverage, installation is compliant from day one, reducing risk and accelerating deployment. The enclosure’s dimensions and 4 lb weight facilitate easier handling during installation and transit, improving on-site efficiency and project cost predictability.
