305-056-520-258

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-258 is a standard card edge connector from the 305 Series, designed for dual-edge board connections. It features 56 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it supports a continuous current rating of 5 A. The housing is made of green thermoplastic, offering a low-profile design suitable for panel mounting.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Low profile insulator body construction
• Gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connection
• Industrial control systems utilizing standardized card edge interfaces
• Equipment needing polarized key compatibility for precise board insertion

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure the correct housing color and contact configuration match the design requirements. Confirm that the target printed circuit board thickness aligns with the 0.062-inch specification for proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS directives if required for the final assembly environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 56 positions is required. The 3.96 mm pitch is suitable for applications where space efficiency does not necessitate finer geometries. Consider the 5 A current rating against the thermal load of the application. The panel mount style dictates the integration method within the chassis structure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by its robust construction and compatibility with polarizing keys. Similar parts in the series vary primarily by the number of positions and specific housing configurations while maintaining consistent electrical and mechanical standards for the 305 line.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 56-position count, 3.96 mm pitch, and dual-edge acceptance. Verify that any alternative component supports the same polarizing key types and panel mounting orientation to ensure mechanical interchangeability without redesigning the enclosure.
