GMA40DRST-S288

Edgeboard Connectors Overview

The GMA40DRST-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 80 positions with a 0.156-inch (3.96mm) pitch and accommodates a board thickness of 0.062 inches (1.57mm). The contacts are made of phosphor bronze with a gold plating thickness of 10.0µin (0.25µm). Designed for through-hole solder termination, it utilizes a polyamide (PA9T) insulator. The unit supports a mounting flange with threaded inserts and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with bellowed contact type for reliable signal transmission
• Mounting flange equipped with threaded inserts for secure mechanical attachment
• Gold-plated phosphor bronze contacts ensure corrosion resistance and conductivity
• Polyamide insulation material provides stability across specified operating temperatures

Edgeboard Connectors Applications

• Adapter board interconnections
• Edge card connections in industrial equipment
• High-reliability electronic assemblies requiring secure mounting

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal style and flange characteristics. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the 0.156-inch pitch matches the design requirements. Check RoHS compliance status if required by project specifications. Validate the threaded insert specification against the mounting hardware available.

Edgeboard Connectors Selection Notes

Select this component when a larger 0.156-inch pitch is required compared to standard 0.100-inch options. The threaded flange feature distinguishes it from non-threaded variants. Consider the phosphor bronze material properties for spring force requirements. Evaluate the PA9T insulation material suitability for the thermal environment. Ensure the dual-row layout fits the available board space constraints.

Edgeboard Connectors Part Context

This model belongs to the GMA series of card edge connectors from Sullins Connector Solutions. The series offers various pitch options and termination styles. The GMA40 variant specifically provides 80 contacts in a dual-row arrangement. The S288 suffix indicates specific packaging and finish details consistent with manufacturer standards for this product line.

Edgeboard Connectors Replacement Considerations

ECC40DRSH-S288 offers similar electrical specs but uses PBT insulation and has a different flange orientation. ACC40DRSS-S288 shares the same pitch but differs in contact material and flange type. Verify mechanical fit and electrical parameters before substitution.
