RSM28DRMT

Edgeboard Connectors Overview

The RSM28DRMT is a dual-row card edge connector manufactured by Sullins Connector Solutions. It features 56 contacts arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes phosphor bronze contacts with gold plating and a polyphenylene sulfide insulator. Designed for through-hole mounting, it supports a card thickness of 0.062 inches and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density board-to-board interconnection
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Polyphenylene sulfide insulator provides thermal stability and durability

Edgeboard Connectors Applications

• High-density electronic assemblies requiring robust edge-card connections
• Industrial control systems operating in extreme temperature environments
• Telecommunications infrastructure utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official Sullins documentation to confirm exact termination style, flange options, and packaging quantities. Ensure the selected variant matches the required PCB hole dimensions and insertion depth specifications for your application design.

Edgeboard Connectors Selection Notes

Select this component when a 0.156-inch pitch dual-row interface is required. Confirm that the PCB edge card thickness aligns with the 0.062-inch specification. Validate that the through-hole termination method is compatible with the manufacturing process and that the operating temperature range meets environmental requirements.

Edgeboard Connectors Part Context

This part belongs to the RSM series of card edge connectors from Sullins Connector Solutions. The series offers various configurations for different mounting styles and contact counts. The RSM28DRMT specifically addresses applications needing 56 positions with a standard pitch, providing a balance between density and mechanical stability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include variants like RSM28DSEN or GCM28DRMI, provided they match the 56-position count, 0.156-inch pitch, and dual-row female configuration. Verify insulation material and termination type compatibility before substitution.
