GBA18DTBD

Edgeboard Connectors Overview

The GBA18DTBD is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 36 positions arranged in two rows of 18 contacts, with a 0.125-inch (3.18mm) pitch. Designed for through-hole right-angle mounting, it accommodates non-specified dual-edge cards with a thickness of 0.062 inches (1.57mm). The contacts are made of phosphor bronze with a bellowed type and gold plating (10.0µin/0.25µm). The insulator is black polyamide (PA9T), supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with bellowed contact type for secure mating
• Through-hole right-angle installation for PCB integration
• Gold-plated phosphor bronze contacts ensuring reliable conductivity
• Polyamide (PA9T) insulator housing for thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm terminal style and flange characteristics. Ensure compatibility with the target PCB layout regarding right-angle orientation and hole dimensions. Confirm that the 0.062-inch card thickness matches the design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.125-inch pitch is required for right-angle through-hole mounting. It is suitable for applications needing high durability due to the bellowed contact design. Consider the PA9T insulation material if higher thermal resistance is needed compared to standard nylon variants.

Edgeboard Connectors Part Context

This part belongs to the GBA series of card edge connectors from Sullins Connector Solutions. The series offers various configurations for different card types and mounting styles. The GBA18DTBD specifically addresses needs for dual-edge, right-angle, through-hole connections with standardized spacing.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include GCA18DTBD or GSA18DTBD, which share similar electrical and mechanical specifications but may differ in insulation material or flange details. Verify exact dimensional tolerances and termination methods before substitution.
