305-056-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-258 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 56 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance. The insulator body is made of thermoplastic material, providing durability in demanding environments.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation color specifications. Ensure compatibility with the target PCB stack-up and mounting hole dimensions. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 56 positions is required. The 3.96 mm pitch suits applications needing wider spacing for higher voltage isolation or mechanical stability. Verify that the panel mount style aligns with the chassis design constraints and thermal management requirements of the final product.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, catering to diverse board-to-board and board-to-panel interface needs. The 305 series is characterized by its low-profile insulator body and reliable solder pin termination methods.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different mounting styles or plating options. Cross-referencing dimensional drawings is essential to ensure mechanical fitment without modifying the host panel design.
