305-068-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-068-520-504 is a standard card edge connector designed for panel mount and through-hole installation. It features 68 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with half-beam lock contacts for secure board retention
• Low-profile insulator body design suitable for space-constrained panel applications
• Gold-plated copper alloy contacts ensure reliable electrical performance in demanding environments

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement instruments needing high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact tail dimensions and insulation material properties. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status via the manufacturer's latest datasheet revision. Cross-reference the Mouser or DigiKey part numbers with the original manufacturer listing to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a 68-position dual-edge interface is required with a 3.96 mm pitch. The vertical mounting style and panel mount feature dictate its use in chassis-based assemblies. Consider the 5 A current rating and thermal limits when designing for high-power signal paths. Verify that the half-beam lock mechanism meets the mechanical retention requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, characterized by a 3.96 mm contact spacing. The series includes various position counts and termination styles. The 305-068-520-504 specifically denotes the 68-position variant with solder pin termination and gold finish. It is distinct from single-row or different pitch connectors within the broader EDAC portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 68-position layouts and 3.96 mm spacing. Verify mechanical footprint and contact locking style before substitution. Generic equivalents may lack the specific half-beam lock retention characteristics.
