20860633

Overview

The nVent SCHROFF 20860-633 is a MultipacPRO series 19-inch rack mount chassis designed for horizontal board assembly. Constructed from aluminum, this robust enclosure features a 4U height and a depth of 400 mm. The unit is finished in grey and includes perforated panels to facilitate airflow and thermal management for internal components. It serves as a complete sub-rack solution for industrial applications requiring durable, low-weight housing.

Feature Summary

• Robust aluminum construction for durability and low weight
• Designed for horizontal board assembly within 19-inch racks
• Perforated panels support effective thermal management

Applications

• Industrial control systems
• Electronic equipment housing
• Horizontal PCB mounting infrastructure

Procurement Notes

Verify the specific part number format, as listings may appear with or without hyphens (e.g., 20860-633 vs 20860633). Confirm that the required depth is exactly 400 mm and the height is 4U. Ensure the perforated panel configuration matches your cooling requirements. Cross-reference the manufacturer standard lead time with current distributor availability before finalizing procurement plans.

Selection Notes

Select this model when a rigid, 19-inch compatible chassis is needed for horizontal circuit board integration. The 4U form factor provides sufficient vertical space for multiple boards while maintaining a compact footprint. The aluminum material offers a balance of structural integrity and weight reduction compared to steel alternatives. Verify that the 400 mm depth accommodates the longest internal component or cable routing needs.

Part Context

This component belongs to the MultipacPRO series, which specializes in rack-mount enclosures for electronic assemblies. The 20860 series specifically addresses the need for standardized 19-inch width compatibility. As a sub-rack, it provides the mechanical framework necessary to secure printed circuit boards in industrial environments, distinguishing it from standalone boxes or open frames.

Replacement Considerations

Direct substitutes must match the 19-inch width, 4U height, and 400 mm depth specifications. Verify that alternative models also utilize aluminum construction and feature perforated panels if active cooling ventilation is required. Ensure the replacement maintains compatibility with standard rack mounting hardware.
