305-042-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-501 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 42 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge insertion
• Panel mount installation style with vertical orientation
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulator for structural integrity

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections
• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact type and plating specifications. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Check for updated datasheets to validate current manufacturing availability and environmental certifications. Ensure compatibility with existing panel cutouts and mating card dimensions.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch offers robust spacing for industrial environments. Consider the panel mount style for fixed installations rather than board-to-board stacking. Verify that the gold plating meets the specific conductivity requirements of the application signals.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in heavy-duty card edge connectors. The series is characterized by its use in demanding environments requiring reliable mechanical and electrical performance. The 305 series typically supports various position counts and mounting styles, catering to diverse industrial and commercial electronics needs.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-042-556-502 or similar variants if different plating thickness or housing color is required. Ensure substitute parts maintain the same 3.96 mm pitch and 42-position count. Verify that alternative manufacturers offer compatible panel mount dimensions and thermal ratings.
