RCM40DTBI-S189

Edgeboard Connectors Overview

The RCM40DTBI-S189 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 80 positions with a 0.156-inch (3.96mm) spacing and supports cards up to 0.062 inches thick. The contacts are made of phosphor bronze with a gold plating thickness of 10.0µin (0.25µm). Designed for through-hole, right-angle mounting, it utilizes a PPS insulator and offers an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for reliable board-to-board connections
• Gold-plated phosphor bronze contacts ensure stable signal transmission
• Green-colored PPS insulator provides high-temperature resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board interfaces
• Consumer electronics internal module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix 'S189' against your schematic requirements to confirm compatibility with existing PCB footprints and mating card specifications. Ensure that the 0.156-inch spacing aligns with your design constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with 0.156-inch spacing is required. Consider the green color coding for visual identification in complex assemblies. Verify that the 0.062-inch card thickness limit matches your target circuit board specifications.

Edgeboard Connectors Part Context

This component belongs to the RCM series of card edge connectors from Sullins Connector Solutions. It is designed for applications requiring durable, high-density connections. The series typically includes various pin counts and spacing options to accommodate different board layout needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins models with identical 0.156-inch spacing and 80-position dual-edge female configurations, such as RCM40DTMD-S189, provided mounting hole patterns and flange characteristics are compatible.
