307-056-424-204

Edgeboard Connectors Overview

The EDAC Inc. 307-056-424-204 is a standard card edge connector from the 307 Series, designed for dual-edge mating with a 56-position configuration. It features a 3.96 mm (0.156 inch) contact spacing and a 5.08 mm row spacing. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with a green thermoplastic polyester insulator body and copper alloy contacts, it utilizes a tin plating finish. This component supports through-hole termination for secure panel or PCB mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two-sided card insertion
• Low-profile insulator body constructed from thermoplastic polyester
• Copper alloy contacts with tin plating for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and insulation color, as variations exist within the 307 series. Confirm that the target application requires a dual-edge receptacle rather than a single-edge variant. Ensure the PCB thickness matches the 1.57 mm specification to guarantee proper mechanical engagement. Cross-reference the manufacturer part number against distributor catalogs to identify any regional availability restrictions or RoHS compliance documentation updates prior to finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for double-sided cards in space-constrained environments. The 3.96 mm pitch allows for significant I/O density while maintaining robust mechanical stability. Consider the tin-plated contacts if cost efficiency is prioritized over the corrosion resistance offered by gold finishes. Verify that the through-hole termination method aligns with the assembly process capabilities of the manufacturing facility.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 307 Series, which specializes in standard card edge solutions. The series is characterized by its consistent 3.96 mm contact spacing and compatibility with 1.57 mm thick PCBs. Variations within the series typically differ by position count, row configuration, and termination style, allowing engineers to scale connectivity requirements while maintaining standardized mechanical footprints across different product lines.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 307 series models with matching 56 positions and dual-edge configurations, such as 307-056-424-207, provided the contact plating difference is acceptable. Generic replacements must strictly adhere to the 3.96 mm pitch and 1.57 mm board thickness constraints to ensure physical compatibility.
