305-056-520-208

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-208 is a dual-edge card edge connector designed for panel mounting applications. It features 56 positions with a contact spacing of 0.156 inches (3.96mm) and a row spacing of 0.140 inches (3.56mm). The connector utilizes female contacts with gold plating and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Termination is achieved via solder tails, and the insulator body is constructed from green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates double-sided PCBs
• Gold-plated female contacts ensure reliable signal transmission
• Solder tail termination facilitates secure board attachment
• Low-profile insulator body reduces overall assembly height

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control hardware interfaces
• Telecommunications equipment backplanes
• Test and measurement instrument connections

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the specified range of 0.062 inches nominal to ensure proper contact engagement. Confirm that the application environment remains within the operational temperature limits defined in the official datasheet. Ensure compatibility with the required soldering profile for the tail termination style to maintain mechanical integrity.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is required for panel-mount configurations. The 56-position count suits moderate-density interconnect needs. Verify that the 0.156-inch spacing aligns with the PCB layout constraints. Consider the low-profile design if vertical space limitations exist within the enclosure structure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and termination styles to support diverse industrial and commercial connectivity requirements. The 305-056 variant specifically addresses applications requiring a high pin count in a compact form factor.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-056-520-503 or 305-056-520-568 for alternative packaging or minor specification variations. Ensure any substitute maintains the same 56-position count and dual-edge geometry.
