SCHROFF Multipac Base 4HE model 20860230 — 4U rack mount base for modular electronics

SCHROFF Multipac Base 4HE model 20860230 is a 4U rack mount base designed to house modular electronic assemblies and subracks. The unit provides a compact chassis platform that accepts plug-in units and modules, enabling standardized mounting, secure retention and tidy cable routing in 19-inch rack systems. Intended for applications where a shallow, serviceable enclosure is required, the base supports integration into industrial control cabinets, telecom racks and laboratory test systems.

Advantages

The Multipac Base offers a consistent mechanical platform for modular electronics, reducing integration time and simplifying maintenance. Its 4U height delivers a balance between module density and accessibility, while the rack-mount form factor ensures compatibility with standard 19-inch equipment racks. The design supports clear front and rear access for module insertion and cabling, allowing organized wiring and safe grounding. Materials and construction are selected to provide mechanical stability and repeatable module alignment.

Suitable for

• Modular plug-in assemblies and subracks in industrial automation
• Telecommunication equipment and field units requiring rack installation
• Laboratory measurement setups and test benches with modular electronics
• Prototype systems and small server or controller enclosures

Key specifications

• Form factor: 4U rack mount base compatible with 19-inch racks
• Intended use: modular electronics, plug-in units and subracks
• Front/rear access: supports insertion and cabling from both sides
• Mechanical features: standardized mounting rails and module guides for secure retention
• Construction: robust chassis suitable for industrial and laboratory environments

How to use

Install the Multipac Base into a standard 19-inch rack using appropriate rack screws and mounting hardware. Slide modular plug-in units into the provided module guides and secure them according to the module retention method used (screws, clips or front panel fixings). Route signal and power cabling through the rear openings, keeping cable runs organized to preserve airflow and service access. Ensure the chassis is properly earthed and that any supplied panels or covers are fitted to maintain structural integrity.

Usage recommendations

Verify compatibility of plug-in modules with the 4U depth and mounting pattern before installation. Use cable management accessories to prevent strain on connectors and maintain serviceability. For environments with vibration or shock, confirm that module retention and any optional locking hardware meet your application’s mechanical requirements.
