305-026-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-201 is a standard card edge connector from the 305 Series, designed for dual female board-to-board or backplane applications. It features 26 positions with a pitch of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing in green. It supports a PCB thickness of 1.57 mm and offers vertical panel mounting without lugs. The component provides reliable electrical interconnection with a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge insertion
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester housing provides durable insulation and structural stability
• Vertical panel mount style facilitates direct integration into chassis systems

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Embedded computing module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material composition, as variations may exist within the 305 series. Confirm that the target application requires the 0.156-inch pitch specification, as this differs from other common connector standards. Ensure compatibility with the intended PCB thickness of 1.57 mm before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a dual female connector with a 0.156-inch pitch is required for vertical panel mounting. The 26-position count suits moderate-density interconnect needs. Consider the thermoplastic polyester housing for environmental durability. Verify that the 5 A current rating meets the circuit requirements and that the absence of mounting lugs aligns with the mechanical design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in high-reliability card edge connectors. The series is characterized by robust construction suitable for demanding industrial environments. The 305-026-520-201 variant specifically addresses applications requiring dual female termination and a standardized 0.156-inch spacing, distinguishing it from single-row or different pitch alternatives within the broader product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and position counts but differing housing colors or plating options, such as 305-026-520-268. Cross-series replacements require careful verification of pitch, row configuration, and mounting style to ensure mechanical and electrical compatibility.
