VRM-04-20-100-50-03-L

Overview

The VRM-04-20-100-50-03-L is a rectangular military specification connector from the AirBorn verSI series. It features a metal body and vertical through-hole termination with a 0.050-inch (1.27mm) pitch. The component provides 80 positions arranged in 4 rows and 20 columns, utilizing male pin contacts. It includes a guide pin for board thicknesses between 0.125 and 0.250 inches, offers a 10.00mm board spacing, and has a tail length of 0.109 inches.

Feature Summary

• Constructed with a durable metal housing for robust environmental protection
• Incorporates a guide pin mechanism to ensure precise alignment during mating
• Designed for vertical printed circuit board mounting via through-hole termination

Applications

• Vertical PCB interconnection requiring high-density signal routing
• Military and aerospace electronic systems demanding MIL-DTL-83513 compliance
• Board-to-board stacking applications with specific thickness constraints

Procurement Notes

Verify the exact suffix configuration against official datasheets before procurement, as variations exist within the verSI family. Confirm that the metal body construction aligns with your thermal and shielding requirements. Ensure the specified board thickness falls within the guide pin operational range of 0.125 to 0.250 inches. Cross-reference the manufacturer's latest revision notes to confirm material specifications and contact plating details.

Selection Notes

Select this model when a conductive metal enclosure is required for EMI shielding or mechanical strength compared to plastic alternatives. The 0.050-inch pitch allows for high I/O density in constrained spaces. Verify compatibility with existing panel cutouts and mating receptacles. Consider the vertical orientation and through-hole mounting style for assembly process integration.

Part Context

This part belongs to the AirBorn verSI series, which offers various configurations including plastic and metal bodies. The 'VRM' prefix specifically denotes a rectangular plug with a metal shell. This distinguishes it from VSM (plastic plug) or VSF (receptacle) variants within the same pitch and row/column architecture.

Replacement Considerations

Direct substitutes include other VRM-series connectors with identical row, column, and pitch counts. Verify that any replacement maintains the metal body construction and guide pin inclusion. Plastic body equivalents like VSM require separate evaluation for shielding and durability needs.
