305-072-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-568 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of green thermoplastic polyester, supporting a board thickness of 1.57 mm. It operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure mating with non-specified double-sided circuit boards
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and electrical insulation
• Straight PCB mount style facilitates direct vertical integration into assembly panels

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized modular connections
• Test and measurement instrumentation needing high-density I/O
• Automotive electronics assemblies demanding reliable thermal performance

Edgeboard Connectors Procurement Notes

Verify the specific suffix code '568' against the official EDAC datasheet to confirm exact contact termination and flange specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status through the manufacturer's latest documentation. Cross-reference the 72-position count and dual-row layout with system requirements. Validate that the straight mounting angle aligns with the mechanical enclosure constraints.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for double-sided card edge applications. The 3.96 mm pitch dictates the trace spacing on the mating board. Gold plating is necessary for environments where oxidation resistance is critical. The 5 A rating per contact must be evaluated against total system power dissipation. Consider the -40°C to +105°C operating range for environmental suitability. Verify that the straight PCB mount style fits the available panel space.
