• Embedded computing platforms requiring right-angle edge connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix S13 against official Sullins documentation to confirm exact plating thickness and material specifications. Ensure the procurement order matches the required right-angle orientation and surface mount termination type. Cross-reference the RoHS compliance status and ECCN classification EAR99 for regulatory adherence. Confirm that the locking feature aligns with the mechanical design requirements of the target application before finalizing purchase orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, right-angle interface is required for double-sided cards. The 0.156-inch pitch dictates compatible card edge dimensions. Verify that the surface mount termination method suits the PCB fabrication capabilities. The locking feature provides additional stability compared to non-locking variants. Ensure the operating temperature range meets the environmental conditions of the intended deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the RMM series of card edge connectors from Sullins Connector Solutions. The series offers various configurations including straddle mount and through-hole options. The RMM28 variant specifically denotes the 28-position per row capacity. This model represents a specialized right-angle, surface-mount solution within the broader family of industrial-grade interconnect devices designed for demanding applications.

Edgeboard Connectors Replacement Considerations

The RMM28DRSS and RMM28DRAH are related models within the same product family. The RMM28DRSS offers a straddle mount option, while the RMM28DRAH provides a right-angle through-hole configuration. Both share similar contact counts and pitch but differ in termination style and mounting method. Verify mechanical fit and electrical continuity before substituting these alternatives.
