305-020-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-020-556-207 is a standard card edge connector from the 305 series, designed for dual female board-to-board applications. It features 20 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) thickness and semi-bellows contact types. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, and it employs solder pin termination for secure panel mounting.

Edgeboard Connectors Feature Summary

• Dual female configuration for non-specified dual-edge card connections
• Semi-bellows contact design ensures reliable signal transmission
• Gold-plated copper alloy contacts provide corrosion resistance
• Thermoplastic polyester insulation offers stable electrical performance

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust interconnects
• Industrial control systems utilizing dual-edge circuit boards
• Test and measurement equipment needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the panel mounting style aligns with the enclosure design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 20-position interface with a 3.96 mm pitch is required. The vertical panel mount style suits applications where space constraints dictate a perpendicular orientation. Consider the 5 A current rating and operating temperature limits to ensure suitability for the intended electrical load and environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series includes various position counts and mounting styles, all sharing common electrical characteristics such as the 3.96 mm pitch and gold-plated contact options. This specific model represents a mid-range configuration within the product line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with different position counts or mounting angles. Verify that any substitute maintains the same 3.96 mm pitch and dual female configuration to ensure mechanical and electrical compatibility.
