305-050-556-507

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-507 is a standard card edge connector designed for dual-edge board insertion. It features 50 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The unit supports a maximum PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A current, it employs a solder pin termination method for secure mounting. The housing is constructed from green thermoplastic material, providing necessary insulation and structural integrity for panel-mounted vertical installations.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting 50 contact positions
• Gold-plated copper alloy contacts for corrosion resistance
• Solder pin termination for robust mechanical connection
• Thermoplastic insulator housing with vertical panel mount style

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Test and measurement instrument module docking
• Computing hardware peripheral expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, insulator color, and termination type compatibility. Ensure the target application requires the specified 3.96 mm pitch and 1.57 mm board thickness tolerance. Confirm that the 5 A current rating aligns with the electrical load requirements of the design. Cross-reference the package quantity and RoHS compliance status with the latest supplier documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for high-reliability applications. The 50-position count suits designs needing moderate I/O density without excessive footprint. Verify that the vertical panel mount orientation fits the chassis constraints. Consider the gold plating requirement for environments where oxidation resistance is critical. Ensure the solder pin termination method matches the available PCB fabrication capabilities and assembly processes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and termination options while maintaining consistent dimensional standards. The 305-050-556-507 variant specifically addresses needs for 50-contact dual-row interfaces. It represents a standardized solution within the broader EDAC portfolio for industrial and commercial electronic interconnects requiring durable panel-mount connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 50-position, 3.96 mm pitch specifications, such as 305-050-556-508 or 305-050-521-501, provided the termination and housing variations match the design requirements. Verify cross-compatibility with third-party connectors only if they strictly adhere to the same dimensional and electrical parameters defined by the original specification.
