FAQs
For installation, note the enclosure footprint of 600 mm wide, 1,012 mm high, and 673 mm deep with a 620 mm installation depth. It ships pre-assembled with a solid gland plate, brush strip, two 19" mounting angles at the front, and depth-variable hinges. Plan cable routing through the left and right side outlets and account for the 21U capacity to allocate space for drives, PLCs, and I/O modules.
Yes. The front and rear frame include 482.6 mm (19 inch) mounting rails and a 25 mm pitch hole pattern, enabling straightforward mounting of standard 19" equipment such as PLCs, drives, and I/O modules. The design supports quick retrofits and future expansions without needing a different enclosure.
The DK 7721.535 offers IP54 protection in conjunction with solid gland plates at the top and bottom, protecting internal components from dust and splash exposure. It also features IK08 impact resistance for robust field use. These ratings support reliable operation in typical factory and process environments.
Pre-configured with mounting rails, gland plates, earth rail, and hinges, the enclosure reduces commissioning time and assembly errors, lowering labor costs. The depth-variable hinge makes future upgrades easier, and the powder-coated sheet steel construction minimizes corrosion risk, extending service life and reducing replacement intervals for OEMs and maintenance teams.
The enclosure leverages IP54 protection, IK08 impact resistance, and a robust mechanical design with a secure locking system. It uses durable powder coating and a safety glass viewing window, which together help maintain a controlled, compliant environment for electronics in industrial settings, while enabling easier maintenance and long-term reliability.
