ECM18DCMS-S288

Edgeboard Connectors Overview

The ECM18DCMS-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 36 total contacts arranged in two rows of 18, with a 0.156-inch (3.96mm) pitch. The connector utilizes phosphor bronze bellowed-type contacts with a gold plating finish and a PBT insulator. Designed for board edge mounting, it accommodates a PCB thickness of 0.062 inches and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with bellowed contact style for reliable signal transmission
• Gold-plated phosphor bronze contacts ensure corrosion resistance and low contact resistance
• PBT insulator material provides structural stability and thermal endurance
• Board edge mounting design facilitates secure installation on specified PCBs

Edgeboard Connectors Applications

• High-density circuit board interconnections
• Industrial control system modules
• Telecommunications equipment backplanes
• Consumer electronics internal interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix requirements against your assembly drawings, as ordering codes may dictate flange or termination variations. Confirm that the target PCB thickness matches the 0.062-inch specification to ensure proper mechanical retention. Check for RoHS compliance status if environmental regulations apply to your production line. Ensure storage conditions maintain the integrity of the gold plating before soldering.

Edgeboard Connectors Selection Notes

Select this component when a 0.156-inch pitch is required for high-current or high-reliability applications. The bellowed contact design offers superior vibration resistance compared to standard straight contacts. Consider the dual-row layout for maximizing I/O density within limited board space. Verify that the mating card edge thickness aligns with the connector's tolerance specifications to prevent insertion force issues.

Edgeboard Connectors Part Context

This part belongs to the ECM series of card edge connectors from Sullins Connector Solutions. The series is characterized by its robust construction and suitability for demanding environments. The ECM18DCMS-S288 specifically addresses needs for medium-density connections with a focus on durability and consistent electrical performance across the operating temperature range.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Sullins series such as ECC or ECA only if pitch and row count match exactly. Verify mechanical dimensions and contact material compatibility before substituting.
