21500078

Overview

The Schroff 21500078 is a subrack component belonging to the Propac series, designed for industrial electronic systems. It features an aluminum housing with a gray finish and measures 155.5 x 470.3 x 376 mm externally. Classified as a 3U rack unit, it includes ventilation capabilities to support thermal management in enclosed environments. The chassis provides mechanical protection and electromagnetic shielding for internal plug-in modules.

Feature Summary

• Constructed from durable aluminum alloy for robust mechanical integrity
• Provides structural support for standard 3U plug-in module installations
• Incorporates ventilation design to facilitate passive airflow and heat dissipation

Applications

• Industrial control system chassis integration
• CompactPCI or VME backplane mounting infrastructure
• Portable test equipment enclosure assembly

Procurement Notes

Verify the specific Propac series designation and dimensional tolerances against the official Schroff datasheet before procurement. Confirm that the aluminum material specification and surface treatment match project requirements. Ensure compatibility with existing 3U module standards and verify ventilation alignment with cooling strategies.

Selection Notes

Select this model when a rigid, shielded 3U framework is required for modular electronics. Evaluate the external depth of 376mm against available rack space. Consider the aluminum construction for applications needing effective electromagnetic interference protection and lightweight portability compared to steel alternatives.

Part Context

This subrack is part of the Schroff Propac family, which specializes in high-quality industrial enclosures and system racks.
