305-026-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 26 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts with a half-bead termination style for reliable signal transmission. Rated for 5 A current at +105°C, it employs a thermoplastic insulator and offers vertical panel mount installation via through-hole solder pins.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Gold-plated copper alloy contacts ensure corrosion resistance and stable conductivity
• Vertical panel mount design with through-hole solder pin termination
• Thermoplastic insulation provides structural integrity within specified temperature ranges

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computing hardware peripheral interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact physical dimensions and plating specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the target PCB design accommodates the required panel mounting hole diameter and vertical clearance constraints defined in the mechanical drawings.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel integration. The 26-position count suits moderate-density interface needs. Verify that the mating card thickness falls within the supported range and that the application environment remains within the -40°C to +105°C operating temperature limits for optimal performance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which encompasses a range of standard card edge connectors. The series is characterized by robust construction suitable for high-reliability environments. Variations within the series typically differ by position count, pitch, and mounting style, while maintaining consistent contact material and termination methods across the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 26-position counts and 3.96 mm pitch, such as 305-026-521-501, provided the housing color and specific flange details match the assembly requirements. Cross-manufacturer replacements require strict verification of mechanical footprint and electrical ratings.
