SCHROFF Komplettgehäuse unshielded PROPAC PRO GEH.3HE 28TE 266T 24576001 rack enclosure

SCHROFF Komplettgehäuse unshielded PROPAC PRO GEH.3HE 28TE 266T 24576001 rack enclosure is an unshielded, rack-mount chassis intended for modular electronic assemblies. The enclosure provides a 3 HE (height units) front panel and 28 TE (module positions) width, offering a compact mechanical framework for mounting cards, modules and plug-in subassemblies in standard industrial or telecom racks. Its unshielded design makes it suitable when electromagnetic shielding is not required and allows flexible access to internal components for integration and prototyping.

Advantages

The enclosure offers a standardized mechanical form factor that simplifies mounting and interchangeability of compatible modules. Its open, unshielded construction reduces weight and manufacturing complexity while providing easy access for wiring, cooling and inspection. The 3 HE height and 28 TE width balance space efficiency and module density, enabling a compact installation in rack systems. The chassis is designed for secure fixation in a rack environment and for straightforward adaptation to various assembly configurations.

Suitable for

• Integration of modular cards and plug-in electronic assemblies in 19-inch racks
• Prototyping and development work where frequent access to internals is needed
• Housing of electronic subassemblies that do not require electromagnetic shielding
• Industrial control cabinets and telecom equipment racks with space for 3 HE units

Key specifications

• Form factor: 3 HE height, 28 TE panel width (266T designation)
• Construction type: unshielded rack-mount chassis suitable for plug-in modules
• Mounting: front panel module slots compatible with standard TE spacing
• Intended use: mechanical housing for modular electronics and subassemblies
• Access: open internal layout for wiring, ventilation and component installation

How to use

Mount the enclosure in a compatible 19-inch rack or cabinet at the intended location, ensuring proper mechanical support for the 3 HE unit. Install compatible front panel modules or carrier cards into the 28 TE positions following the module supplier's mounting instructions. Secure modules with the provided fasteners and route wiring and connectors to maintain clear airflow and service access. Because the enclosure is unshielded, place systems sensitive to electromagnetic interference in environments where shielding is not required or provide external mitigation as needed.

Usage recommendations

Use the chassis for mechanical housing, prototyping and low-EMI environments; consider external filtering or additional shielding for installations near strong RF sources or where conducted emissions must be controlled.
