305-026-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-026-556-208 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual-edge female configuration with 26 positions and a pitch of 0.156 inches (3.96 mm). The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing durability and environmental resistance for industrial interconnect needs.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, plating thickness, and keying options. Ensure compatibility with the target PCB edge thickness of 1.57 mm before procurement. Confirm that the required polarizing key type matches the available between-contact or in-contact configurations specified by EDAC Inc. for this series.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount card edge connector with 26 positions is required. The 3.96 mm pitch and dual-edge design are critical for matching the mating card specifications. Consider the 5 A current rating and 1800 VACrms dielectric strength for circuit safety requirements. Verify that the green thermoplastic housing meets the environmental and aesthetic constraints of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are engineered for general-purpose and specialized industrial applications. The series offers various position counts and mounting styles, with the 305-026 variant specifically addressing mid-density connection needs. EDAC Inc. designs these connectors to withstand rigorous operational conditions while maintaining consistent electrical performance across diverse sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series parts with identical 26-position dual-edge configurations, such as 305-026-556-204 or 305-026-556-568, provided the specific suffix variations align with the required keying and plating specifications. Cross-brand replacements require careful verification of pitch, board thickness, and current ratings.
