20809533

Overview

The Schroff 20809533 is a ventilated plug-in unit (PIU) card frame designed for high-frequency applications. Constructed from aluminum with an anodized front and chromated rear finish, it provides electromagnetic shielding via a stainless steel gasket. The unit measures 103.12 mm in width, 106.68 mm in height, and 167 mm in depth. It conforms to the 3U rack standard and offers 21 horizontal positions (HP). This shielded kit is intended for integration into modular rack systems requiring robust signal integrity.

Feature Summary

• High-frequency electromagnetic shielding using a stainless steel gasket
• Ventilated design for thermal management
• Aluminum construction with specific surface finishes

Applications

• High-frequency electronic equipment racks
• Shielded modular plug-in unit assemblies
• Industrial control cabinet installations

Procurement Notes

Verify the exact part number against official nVent SCHROFF documentation to ensure compatibility with existing rack frames. Confirm that the required shielding specifications match the stainless steel gasket details provided in the datasheet. Check for any recent product change notices regarding material composition or dimensional tolerances before finalizing procurement orders.

Selection Notes

Select this component when high-frequency interference protection is critical within a 3U form factor. Ensure the system requires a ventilated chassis to manage heat dissipation effectively. Verify that the 167mm depth fits within the available rack space constraints. Consider the aluminum material properties for weight and corrosion resistance requirements in the deployment environment.

Part Context

This plug-in unit belongs to the nVent SCHROFF PIU HF series, specialized for high-frequency shielding. It complements other accessories like handles and backplanes within the same modular ecosystem. The product line focuses on providing standardized, shielded enclosures for sensitive electronic modules in demanding industrial and telecommunications environments.

Replacement Considerations

Consult official nVent SCHROFF substitution guides for verified alternatives. Generic equivalents may lack the specific stainless steel gasket shielding or precise dimensional tolerances required for high-frequency performance.
