The ADPX4B is a small UL 4X external data pocket manufactured by Hoffman Enclosures, Inc. Constructed from 16-gauge steel in medium gray, it features a hinged front for easy access to stored documentation. The unit includes a foam-in-place gasket designed to protect contents from harsh environments. It is specifically engineered for use with A70E series enclosures and holds UL 508-A approval.
Verify the specific material configuration (mild steel or stainless steel) required for your application, as options may exist to match the enclosure finish. Confirm compatibility with the A70E series enclosure model. Ensure the UL 508-A approval status meets your regulatory requirements. Check standard lead times, which are typically around four weeks.
Select this component when external documentation storage is needed for A70E series enclosures. The small size accommodates limited space constraints while providing UL 4X protection. Choose based on the need for a hinged front access mechanism and integrated gasket sealing against environmental factors.
This part belongs to the Hoffman Enclosures accessory line, designed to complement their metal enclosure systems. It serves as an external add-on for data management, ensuring critical information remains accessible yet protected within industrial settings.
No public confirmed substitute part numbers are available in the provided documentation.
