ABB25DHRN

Overview

The ABB25DHRN is a 50-position female card edge connector designed for straddle mount board edge applications. It features dual gold contacts with a 0.050 inch (1.27mm) contact spacing. The housing is constructed from black polyphenylene sulfide (PPS) insulation material, providing robust mechanical stability and thermal resistance for reliable electronic interconnections in demanding environments.

Feature Summary

• Dual-sided female contact configuration for comprehensive signal routing
• Straddle mount design ensures secure board edge alignment
• Gold-plated contacts maintain low resistance and corrosion resistance
• Polyphenylene sulfide housing offers high thermal stability

Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Computing hardware expansion cards
• Test and measurement instrument interfaces

Procurement Notes

Verify the specific suffix codes against official Sullins Connector Solutions documentation to confirm exact plating thickness and insulation material grades. Ensure mounting hole dimensions match the straddle mount specification. Cross-reference the 50-position count and 0.050-inch pitch with the target PCB layout to prevent mechanical interference during assembly.

Selection Notes

Select this component when dual-edge connectivity is required for high-density signal transmission. The straddle mount style provides superior mechanical retention compared to single-edge variants. Consider the PPS insulation properties for applications involving elevated operating temperatures or reflow soldering profiles that demand high heat resistance.

Part Context

This part belongs to the ABB series of card edge connectors manufactured by Sullins Connector Solutions. The series focuses on providing reliable interconnect solutions for board-to-board and board-to-backplane applications. The ABB25DHRN specifically addresses needs for dual-sided female connections with standardized spacing.

Replacement Considerations

Consult official cross-reference guides for compatible alternatives. Verify that substitute parts maintain identical 50-position counts, 0.050-inch pitch, and straddle mount configurations to ensure mechanical compatibility.
