RCM40DCMI-S288

Edgeboard Connectors Overview

The RCM40DCMI-S288 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 80 positions arranged in two rows with a 0.156-inch (3.96mm) contact pitch. The contacts are hairpin bellows type, made of phosphor bronze with gold plating. Designed for surface mount installation, it accommodates PCBs with thicknesses typically ranging from 0.062 to 0.125 inches. The insulator material is polybutylene terephthalate (PBT), providing UL 94V-0 flammability rating. Operating temperature range is -65°C to 150°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure connection to double-sided circuit boards
• Hairpin bellows contact style ensures reliable mating and unmating cycles
• Gold-plated phosphor bronze contacts provide corrosion resistance and low contact resistance
• Surface mount termination allows for automated assembly processes

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing high-density signal routing
• Test and measurement instruments needing frequent card insertion
• Computing hardware modules with dual-edge card interfaces

Edgeboard Connectors Procurement Notes

Verify the specific PCB thickness requirement against the datasheet specifications before ordering. Confirm that the surface mount footprint matches the design layout. Ensure compatibility with reflow soldering profiles suitable for lead-free assemblies. Check for any required polarizing keys if orientation locking is necessary for the application.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. Consider the hairpin bellows contact style for applications demanding high durability. Verify that the surface mount package fits within the available board space. Compare insulation material properties against environmental conditions such as temperature and humidity.

Edgeboard Connectors Part Context

This part belongs to Sullins Connector Solutions' edgeboard connector family. It is designed for high-reliability applications where secure electrical connections are critical. The dual-edge design supports complex circuitry on both sides of the card. Similar parts in the series may vary in pitch, position count, or termination style.

Edgeboard Connectors Replacement Considerations

Direct substitutes include RCM40DCMD-S288 and ECM40DCMT-S288, though terminal types differ. Verify mechanical dimensions and electrical ratings before cross-referencing. Ensure that any replacement maintains the same contact pitch and row configuration.
