305-026-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-503 is a dual-edge female card edge connector from the 305 Series. It features 26 positions with a 0.156-inch (3.96mm) contact spacing and 0.140-inch (3.56mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). It utilizes gold-plated contacts on a copper alloy base, housed in a black thermoplastic polyester insulator. Rated for 5A current at +105°C maximum operating temperature, it offers 5 GOhms insulation resistance and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated contacts ensure reliable signal transmission
• Low-profile insulator body design for space-constrained applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Computing hardware peripheral interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating thickness and material specifications against project requirements. Ensure compatibility with the target PCB thickness range of 0.062 inches nominal. Confirm that the panel mount or through-hole installation method aligns with the mechanical assembly design. Check for RoHS3 compliance documentation if environmental regulations apply to the final product deployment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 0.156-inch pitch is required for 26-position circuits. Consider the 5A current rating and +105°C temperature limit for thermal management planning. Evaluate the low-profile housing dimensions against available vertical clearance in the enclosure. Compare alternative series members if different board thickness tolerances or contact materials are necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series provides various position counts and mounting styles for general-purpose electronic interconnections. The 305-026 variant specifically addresses mid-density connection needs within industrial and commercial electronics sectors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 Series parts for position count variations. Verify mechanical fit with existing panel cutouts and PCB layouts before substitution.
