305-050-556-201

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-201 is a standard card edge connector receptacle featuring 50 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch with a 3.56 mm row spacing. Designed for PCB mounting at a straight angle, it accepts boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, rated for 5 A current, and terminate via solder pins. The insulator body is green thermoplastic.

Edgeboard Connectors Feature Summary

• Dual-row female connector design for secure board engagement
• Gold-plated copper alloy contacts ensure reliable conductivity
• Low-profile thermoplastic insulator body accommodates standard PCB thicknesses
• Straight-mount configuration facilitates direct panel or board integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust signal interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing reliable high-current connections
• Test and measurement instrumentation hardware

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating thickness, insulation color, and mounting style variations within the 305 series. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the straight-mount orientation aligns with the mechanical assembly requirements. Cross-reference the 50-position count against the system's I/O needs to prevent pin mismatch during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for 1.57 mm thick boards. The 5 A rating supports moderate power distribution alongside signal transmission. Consider the straight mounting angle for space-constrained vertical alignments. Verify environmental operating ranges if deployed in extreme temperature conditions beyond standard commercial limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial applications. The series offers various position counts and mounting options, maintaining consistent 3.96 mm pitch specifications across models. This specific model represents a mid-range position count suitable for complex module interconnections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 50-position dual-row configurations and matching pitch dimensions. Ensure any replacement maintains the same 1.57 mm board thickness tolerance and straight-mount orientation to preserve mechanical fit.
