ABC20DRAI-S734

Edgeboard Connectors Overview

The ABC20DRAI-S734 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 40 positions arranged in two rows of 20 contacts with a 0.100 inch (2.54 mm) spacing. The connector utilizes copper beryllium contacts with gold plating, specifically 10.0 µin (0.25 µm) thickness, and full bellows contact types. Designed for through-hole mounting and solder termination, it accommodates non-specified dual-edge cards up to 0.031 inches thick. The insulator is constructed from polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to 150°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with full bellows contacts for reliable signal transmission
• Gold-plated copper beryllium contacts ensure corrosion resistance and low contact resistance
• Polyphenylene sulfide insulation provides high thermal stability and mechanical strength
• Flange features include top mount opening and threaded inserts for secure panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing dual-edge module connections
• Test and measurement instruments needing stable high-temperature performance
• Automotive electronics modules with specific mounting requirements

Edgeboard Connectors Procurement Notes

Verify the specific suffix S734 corresponds to the required flange characteristics and material composition. Confirm that the gold plating thickness meets the application's durability standards. Ensure the PCB design aligns with the 0.100 inch pitch and dual-edge card specifications. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with gold contacts is required for high-reliability applications. The PPS insulator and bellows contacts offer superior performance compared to standard tin-plated alternatives. Consider the flange mounting options for secure integration into chassis designs. Evaluate the thermal rating to ensure compatibility with high-temperature operational environments. Compare pin counts and spacing requirements against alternative connectors in the ABC series.

Edgeboard Connectors Part Context

This part belongs to the ABC series of card edge connectors from Sullins Connector Solutions. The series offers various configurations for single and dual-edge applications. The ABC20 variant specifically provides 40 positions, balancing density and spacing. The S734 suffix indicates specific material and flange attributes within the product line. This series is designed for through-hole mounting and solder termination.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include ABC20DRAS-S734 for tin-plated variants or ABC20DRTI-S734 for different flange configurations. Verify contact material and plating thickness when substituting to maintain electrical performance. Ensure the replacement matches the 0.100 inch pitch and dual-edge card thickness requirements. Check insulation material compatibility for thermal and chemical resistance.
