RSM25DTAT-S189

Edgeboard Connectors Overview

The RSM25DTAT-S189 is a dual-edge card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25, with a pitch of 0.156 inches (3.96mm). Designed for through-hole right-angle mounting, it accepts cards with a thickness of 0.062 inches (1.57mm). The contacts are made of phosphor bronze with a gold finish of 10µin (0.25µm) and utilize loop bellows contact types.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Loop bellows contact type for reliable engagement
• Right-angle through-hole termination method
• Gold-plated phosphor bronze contacts

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Embedded computing modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix 'S189' against official manufacturer documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the required PCB layout for right-angle through-hole mounting. Confirm that the 0.156-inch pitch matches the target card edge design parameters before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 0.156-inch pitch is required for right-angle board-to-board connections. Consider the loop bellows contact style for applications needing robust mechanical retention. Verify that the 50-position count fits the system's signal routing requirements and that the 0.062-inch card thickness specification aligns with the mating hardware.

Edgeboard Connectors Part Context

This part belongs to the RSM series of edgeboard connectors from Sullins Connector Solutions. The series typically offers various position counts and pitch options for dual-edge applications. The RSM25 variant specifically addresses designs requiring 50 total positions across two rows, providing a standardized interface for industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include the RSM25DSAN, which shares the same 50-position, 0.156-inch pitch, and dual-edge female characteristics. Both parts utilize similar contact materials and mounting styles. Verify insulation material and temperature ratings if environmental conditions differ significantly between the original and replacement components.
