20817864

Overview

The nVent SCHROFF 20817864 is a plug-in unit designed for VME bus systems, classified as a non-shielded component. It features a trapezoidal shape and is constructed from plastic material, specifically identified as type 2 in grey coloration. The unit has physical dimensions of 3 HE (Horizontal Units) height and 8 TE (Terminal Units) width. This component serves as a front panel or blanking element within rack-mounted electronic enclosures, providing structural integration without electromagnetic interference shielding properties.

Feature Summary

• Non-shielded construction suitable for applications not requiring EMI protection
• Trapezoidal design optimized for specific VME chassis mounting configurations
• Plastic composition offering lightweight structural support

Applications

• VME bus system front panel integration
• Rack-mounted electronic enclosure blanking
• Non-shielded module placeholder installation

Procurement Notes

Verify the exact material specification and dimensional tolerances against the official nVent SCHROFF datasheet before procurement. Confirm that the non-shielded nature aligns with your system's electromagnetic compatibility requirements. Ensure the trapezoidal profile matches your existing chassis mounting standards to avoid fitment issues during assembly.

Selection Notes

Select this part only when EMI shielding is unnecessary for the specific slot application. Compare the 3 HE by 8 TE dimensions against available rack space to ensure proper fit. Consider alternative shielded variants if future regulatory compliance requires enhanced electromagnetic isolation. Validate the plastic type compatibility with environmental conditions expected in the deployment location.

Part Context

This component belongs to the nVent SCHROFF 20817 series, which specializes in aluminum and plastic front panels for industrial computing racks. The series provides standardized mounting solutions for VME and other bus architectures. The 20817864 variant specifically addresses non-shielded needs, distinguishing it from its EMI-protected counterparts within the same product family.

Replacement Considerations

Direct substitutes include other 3 HE by 8 TE non-shielded VME plug-in units from the same manufacturer. Verify mechanical interface compatibility before swapping. Cross-reference with similar models like 20817865 or 20817866 if minor dimensional variations are acceptable.
