391-072-560-203

Edgeboard Connectors Overview

The EDAC Inc. 391-072-560-203 is a dual-edge female card edge connector from the 391 series, designed for high-reliability applications. It features 72 positions with a 0.100" (2.54mm) pitch and supports board thicknesses of 0.054" to 0.070" (1.37mm to 1.78mm). The connector utilizes gold-plated copper alloy contacts with a 10.0µin plating thickness for stable signal transmission. Constructed with a black thermoplastic polyester housing, it offers a -40°C to +105°C operating temperature range. Key mechanical features include double flanges and .116" floating eyelets for secure panel mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with 72 positions for robust signal connectivity
• Gold-plated copper alloy contacts ensure reliable electrical performance
• Double flange design with floating eyelets for secure panel installation
• Thermoplastic polyester housing provides durability in demanding environments

Edgeboard Connectors Applications

• Industrial control systems requiring durable interconnects
• Telecommunications equipment needing reliable signal paths
• Test and measurement devices utilizing standard card edge interfaces
• Automotive electronics operating within specified temperature ranges

Edgeboard Connectors Procurement Notes

Verify that the required PCB thickness falls within the 0.054" to 0.070" specification range to ensure proper contact engagement. Confirm that the mating card edge meets the 0.100" pitch requirement. Ensure panel cutouts align with the double flange dimensions and .116" floating eyelet placement for correct mechanical fit. Check for any specific environmental certifications if the application involves harsh conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 72 positions is required. The 0.100" pitch is suitable for general-purpose digital and analog signals. Consider the thermoplastic polyester material for its balance of strength and cost. The floating eyelet feature is advantageous for applications requiring tolerance to panel misalignment during assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 391 series of card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting options to accommodate different form factors. The 391-072-560-203 specifically addresses needs for higher pin counts with secure panel mounting capabilities, fitting into standard industrial and commercial hardware architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 72-position count, 0.100" pitch, and dual-edge female configuration. Verify compatibility with the 0.054" to 0.070" board thickness range. Ensure the replacement also features gold-plated contacts and similar mounting hardware like floating eyelets to maintain mechanical integrity.
