305-032-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-032-555-558 is a standard card edge connector designed for dual female board-to-board applications. It features 32 positions with a contact pitch 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 featuring gold plating, it provides a continuous current rating of 5 A and withstands 1800 VACrms. The unit utilizes a straddle mount installation style with an insulator body made from thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body for compact assembly requirements
• Designed as a card extender with integrated card guide solutions

Edgeboard Connectors Applications

• Board edge interconnections requiring straddle mount stability
• Card extender systems utilizing polarizing key integration
• High-reliability electronic assemblies needing 5A current capacity

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination type and mounting variations. Ensure compatibility with the required PCB thickness of 0.062 inches. Confirm that the selected variant matches the intended polarizing key configuration. Cross-reference the manufacturer part number with authorized distributors to validate current availability status and lead times before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The straddle mount design offers enhanced mechanical stability compared to surface mount alternatives. Verify that the application environment supports the specified operating temperature range. Ensure the mating card meets the 0.062 inch thickness specification to guarantee proper contact engagement and electrical continuity within the connector housing.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for demanding industrial environments. Variants within the series differ primarily in position count, termination style, and mounting orientation. The 305 series generally emphasizes durability and precise alignment through optional polarizing key accommodations.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 32-position count, 3.96 mm pitch, and straddle mount configuration. Verify that alternative components support the same 0.062 inch PCB thickness and provide equivalent 5A current ratings. Check for compatible polarizing key acceptance if mechanical locking is required in the assembly.
