ASM28DRMD-S288

Edgeboard Connectors Overview

The ASM28DRMD-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 28 total positions arranged in two rows of 14 contacts each, with a standard 0.100-inch (2.54mm) spacing. The connector utilizes bellows-style contacts made from beryllium copper and finished with a 30.0µin (0.76µm) gold plating for reliable signal transmission. Designed for board edge mounting with cross-riding capabilities, it accommodates a card thickness of 0.062 inches (1.57mm). The unit operates within a temperature range of -65°C to 150°C and employs polyphenylene sulfide (PPS) insulation material.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with bellows-style contact design for secure mating engagement
• Cross-riding board edge installation capability with flat flange features
• High-temperature operational stability utilizing PPS insulation material

Edgeboard Connectors Applications

• Interconnection between circuit boards and backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct contact plating thickness and material composition. Confirm that the required card edge thickness matches the specified 0.062-inch tolerance. Cross-reference the flange opening dimensions to guarantee compatibility with existing mounting hardware before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when high-temperature performance up to 150°C is required alongside standard 0.100-inch pitch spacing. The beryllium copper construction offers superior spring properties compared to phosphor bronze alternatives. Ensure the application environment supports the specified PPS insulation characteristics and verify that the dual-row layout fits within the available board real estate constraints.
