305-022-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-022-520-502 is a standard card edge connector header featuring 22 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and is designed for .140 inch (3.56 mm) row spacing. The component accepts printed circuit boards with a nominal thickness of 1.57 mm (.062 inch). Electrical specifications include a 5 A continuous current rating and an insulation resistance of 5 GOhms. The contacts are gold-plated copper alloy, while the insulator body is green thermoplastic.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact panel mounting applications
• Dual-edge card edge interface with solder pin termination

Edgeboard Connectors Applications

• Panel mount interconnect systems requiring vertical orientation
• Industrial control modules utilizing standard thickness PCBs
• Communication equipment backplanes needing polarized keying options

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact material certifications. Ensure that the ordering suffix matches the required termination style and contact plating thickness. Cross-reference the part number against the manufacturer's latest release notes to identify any potential obsolescence or alternate package configurations before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating supports moderate power distribution needs. Verify compatibility with the target PCB thickness of 1.57 mm and ensure the housing color meets visual identification requirements. Confirm that the solder pin termination aligns with the assembly process capabilities.
