305-026-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-204 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 26 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and employs a solder pin termination type.

Edgeboard Connectors Feature Summary

• Dual edge female connector design for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester insulator provides durable housing
• Vertical panel mount style facilitates structured installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation panels
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material composition, as variations exist within the 305 series. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the manufacturer datasheet for precise dimensional tolerances and mating force specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided female connection is required for a 26-position interface. The 0.156-inch pitch suits applications needing wider spacing for high-current or high-voltage isolation. The vertical orientation is optimal for space-constrained panel layouts where horizontal clearance is limited. Verify that the thermoplastic insulation meets the environmental temperature ratings of the operating system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate diverse board sizes. The 305-026 variant specifically addresses mid-range density requirements, balancing connectivity needs with physical footprint constraints in modular electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 26-position dual female configurations and matching 0.156-inch pitch. Verify that alternative options maintain the same vertical panel mount style and solder pin termination. Ensure any replacement matches the 0.062-inch PCB thickness specification to guarantee proper mechanical retention and electrical contact.
