305-082-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-207 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 82 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact pitch and is compatible with printed circuit boards of nominal thickness 1.57 mm (0.062 inch). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The unit operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body construction
• Utilizes gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm that the received part matches the specific 305-082-521-207 designation and series requirements. Ensure compliance with RoHS directives as indicated in official documentation. Check for any regional distribution restrictions prior to ordering.

Edgeboard Connectors Selection Notes

Select this model when a high-density dual-row interface is required for thick PCBs. The 3.96 mm pitch accommodates substantial signal routing needs. Verify compatibility with existing polarizing key mechanisms if used in constrained spaces. Ensure the panel mounting style aligns with the mechanical design constraints of the target enclosure.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent electrical and mechanical characteristics. The 305-082 variant provides a higher contact density suitable for complex signal processing applications requiring stable vertical connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical pitch and row configurations. Verify that alternative models support the same 1.57 mm board thickness and 5 A current rating. Cross-reference specific pin counts to ensure functional equivalence in the target assembly.
