305-050-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-503 is a dual-row female card edge connector designed for standard PCB applications. It features 50 positions with a 0.156-inch (3.96mm) contact spacing and 0.140-inch (3.56mm) row spacing. The unit utilizes gold-plated copper alloy contacts with a 10.0µin thickness, housed in a green thermoplastic insulator. Rated for 5A continuous current and 1800VACrms, it supports board thicknesses of approximately 0.062 inches (1.57mm). Operating temperature ranges from -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Low profile insulator body design for compact integration
• Gold-plated contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Standard card edge interconnect systems
• Industrial control modules requiring polarized connections
• High-voltage signal routing applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm compatibility with required polarizing key configurations and mounting styles. Ensure the target printed circuit board thickness aligns with the specified nominal 0.062-inch requirement for proper mechanical engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female interface with 0.156-inch pitch is required. Confirm that the application environment falls within the -40°C to 105°C operating range. Verify that the system voltage does not exceed the 1800VACrms rating and that the current load remains within the 5A continuous limit for safe operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for general-purpose electronic interconnections. The 305-050 designation indicates a 50-position configuration within this established product line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes. Compatible alternatives may include variants with different insulation colors or minor dimensional adjustments while maintaining the same 50-position dual-row specification.
