GBM18DRMS

Edgeboard Connectors Overview

The GBM18DRMS is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 36 contacts arranged in two rows of 18 positions each, with a contact center spacing of 0.156 inches (3.96 mm). The connector utilizes phosphor bronze clip bellow contacts with a gold plating thickness of 10.0 µin (0.25 µm). Designed for through-hole solder termination, it accommodates a card thickness of 0.062 inches (1.57 mm). The insulator is constructed from polyamide PA9T nylon 9T, and the unit operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with clip bellow contact style for reliable signal transmission
• Gold-plated phosphor bronze contacts ensure corrosion resistance and low contact impedance
• Polyamide PA9T insulator provides high thermal stability and mechanical durability
• Through-hole mounting with side-mounting eyelets for secure board installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module connections
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required dual-edge female configuration and 0.156-inch pitch. Confirm compliance with RoHS3 standards and REACH regulations before integration. Ensure the PCB layout supports through-hole soldering and aligns with the specified 0.062-inch card thickness. Cross-reference the insulator material properties against operational temperature requirements to guarantee long-term reliability in the target environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 36 positions is required for rigid board applications. The 0.156-inch pitch suits standard industrial layouts. Consider the gold plating thickness for environments requiring enhanced conductivity. Verify that the side-mounting eyelet design fits the mechanical constraints of the assembly. Ensure the operating temperature range meets the environmental conditions of the final product deployment.

Edgeboard Connectors Part Context

This connector belongs to the GBM18 series, which defines the fundamental electrical and mechanical specifications such as pitch and contact count. The suffix DRMS indicates specific terminal, flange, and packaging variations within this family. Understanding the base series parameters helps in identifying compatible mating cards and ensuring consistent performance across similar connector selections in complex assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GMM18DRMS, which shares identical electrical characteristics but may differ in terminal style or flange features. Verify mechanical compatibility, particularly regarding mounting eyelets and insulator height, before swapping parts. Ensure that any replacement maintains the same contact material, plating thickness, and operating temperature range to preserve system integrity.
