305-050-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-268 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual-row configuration with 50 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is specified as 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, housed in a green thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design with half-beam contact type for secure board retention
• Vertical panel mount style with flange features including top-open holes and M3 threaded inserts
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic insulator body providing structural integrity within specified temperature ranges

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing high-reliability signal connections
• Automotive electronics modules with specific board thickness requirements

Edgeboard Connectors Procurement Notes

Verify that the target application strictly requires a 1.57 mm PCB thickness to ensure proper mechanical fit and electrical contact. Confirm that the vertical panel mount orientation with M3 threaded insert flanges aligns with the chassis design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 5 A current rating meets the system's power distribution needs without derating issues.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for vertical installation. The 50-position count suits applications needing moderate I/O density. Consider the gold plating for corrosion resistance in demanding environments. The thermoplastic housing offers cost-effective durability compared to metal shells. Verify compatibility with existing tooling for M3 fastener installation during assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standardized card edge connectors with 3.96 mm contact spacing. The series includes various position counts and mounting options to support diverse electronic packaging needs. The 305 Series is known for its low-profile insulator body and reliable performance in industrial settings. This specific model represents a common configuration within the broader product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-040-520-268 or 305-052-520-268, differing primarily in position count. Cross-series replacements may require verification of row spacing and board thickness compatibility. Ensure any alternative maintains the 3.96 mm pitch and vertical mounting characteristics to preserve mechanical integration.
