305-040-555-568

Edgeboard Connectors Overview

The EDAC Inc. 305-040-555-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 40 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). It utilizes female contacts made of copper alloy with gold plating to ensure reliable signal transmission. The unit supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The insulator body is constructed from green thermoplastic polyester, providing robust insulation and environmental resistance.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features low profile insulator body for compact assembly requirements
• Provides high dielectric strength with 1800 VACrms rating

Edgeboard Connectors Applications

• Dual-edge card edge interconnections
• Panel mount vertical installations
• High-density electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact finish, and mounting style. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the required polarizing key configuration matches the design specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for non-specified dual-edge cards. The 3.96 mm pitch suits applications needing wider spacing than standard connectors. Verify that the panel mount style aligns with the chassis design constraints and that the 5 A current rating meets the system power distribution requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts up to 86 contacts upon request. These connectors are engineered for durability and reliable performance in industrial and commercial electronic environments requiring secure board-to-panel connections.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers within the same family. Substitutes must match the 40-position count, 3.96 mm pitch, and dual-edge female contact type. Verify mechanical dimensions and mounting flange specifications to ensure interchangeability.
