Quick Summary
Wall-mounted enclosures DK 7721.135 provide secure, accessible housing for electrical controls in industrial panels. On-site wiring often suffers from limited access and depth constraints, slowing maintenance and increasing error risk. These ratings—IP 55 protection and IK08 impact resistance—coupled with a depth-variable hinged part, streamline service and future upgrades. Powder-coated sheet steel and a glazed door help ensure long-term reliability, while the 21 U interior supports a range of PLCs, drives, and terminal blocks. For procurement and install teams, the pre-configured package reduces field assembly time and guarantees consistent quality across panels, delivering lower total cost of ownership. Finally, the enclosure's compatibility with standard 19-inch equipment and punched rails supports scalable, modular automation architectures.

Product description
DK Wall-mounted enclosures, 3-part, WHD: 600x1012x473 mm, 21 U, With punched rails, and mounting angles, depth-variable
The three-part DK wall-mounted design with a depth-variable hinged section directly improves serviceability by allowing technicians to access mounted components without removing the entire enclosure, reducing maintenance time and downtime in automation cabinets. This translates to measurable efficiency gains on busy production lines and enables rapid upgrades as control logic evolves. Internally, 21 U of space in a compact 600x1012x473 mm footprint accommodates common PLCs, drives, and terminal assemblies, while punched rails and front-rear 25 mm pitch holes simplify cable routing and block mounting, cutting installation labor and ensuring clean, compliant wiring layouts for robust industrial IT infrastructure. The IP 55, IK08-rated enclosure, powder-coated in RAL 7035 with a designer glazed door, guards against dust and impact while preserving visibility and security in demanding environments, supporting reliable operation of automated processes. Pre-installed mounting angles, solid gland plate, and two front 19" mounting brackets streamline field assembly, reduce part count, and lower total project risk for panel builders and integrators. Together, these features enable scalable, modular control cabinets that align with industry standards for IT and automation deployment, reducing both risk and total cost of ownership.

FAQs
The enclosure includes two front 482.6 mm (19 in) mounting angles and pre-fitted punched rails, enabling straightforward integration of standard PLCs, drives, and terminal blocks. With 25 mm pitch front and rear holes, you can mount common 19-inch equipment without additional adapters, reducing install time and ensuring secure alignment.
Installation depth is 420 mm, with overall dimensions 600x1012x473 mm. Clearance width is 502 mm and clearance height is 949 mm, providing ample room for cable entry, gland plates, and rear wiring. This helps maintain proper airflow and simplifies cable clamping for reliable operation in automated systems.
Yes, the enclosure is IP55 protected, guarding against dust ingress and water spray, and has IK08 impact resistance for robust mechanical protection. This combination is suitable for demanding factory floors and outdoor-adjacent installations where dust, moisture, and incidental impacts are considerations.
The DK 7721.135 includes a security lock with a comfort handle and 2-point locking, plus a double-kit key. The glazed door provides visibility while maintaining security, helping compliant access control for regulated environments and reducing the risk of tampering.
Pre-configured with gland plates, rails, mounting angles, and wall brackets, this enclosure minimizes field assembly time and part counts. The depth-variable hinged door simplifies upgrades, while durable powder-coated sheet steel extends service intervals, lowering maintenance costs and accelerating time-to-value for automation projects.
