305-026-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-208 is a standard card edge connector header featuring 26 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and is designed for .140 inch row spacing. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (.062 inch). Constructed with copper alloy contacts plated with gold, the connector supports a continuous current rating of 5 A. It employs a solder pin termination type and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from green thermoplastic material
• Provides high insulation resistance rated at 5 GOhms

Edgeboard Connectors Applications

• Industrial control systems requiring reliable panel-mounted interconnects
• Communication equipment utilizing standardized card edge interfaces
• Electronic modules requiring polarized connection stability

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or Northern Technologies channels. Confirm that the specific suffix matches the required 26-position configuration and gold plating specifications. Ensure compatibility with existing panel mounting hardware and PCB thickness tolerances before final acquisition.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge interface with a 3.96 mm pitch is required. The 5 A current rating and gold-plated copper alloy contacts ensure durability for repeated mating cycles. Verify that the target application supports vertical panel mounting and accommodates the specified 1.57 mm board thickness constraint.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors designed for robust electronic interconnections. The series offers various position counts while maintaining consistent electrical characteristics and mechanical dimensions. The 305-026-521-208 specifically addresses applications needing a 26-position dual-row interface within this established product family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical 3.96 mm pitch and 26-position configurations. Ensure substitute headers maintain matching gold plating, solder pin termination, and vertical panel mount styling for direct interchangeability.
