GBB35DHBT

Edgeboard Connectors Overview

The GBB35DHBT is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 70 positions arranged in two rows of 35 contacts each, with a 0.050-inch (1.27mm) pitch. The connector utilizes phosphor bronze hairpin bellows contacts with a 10.0µin (0.25µm) gold plating thickness for reliable signal transmission. Designed for through-hole, right-angle installation, it employs staggered solder termination. The housing is constructed from black polyamide (PA9T) nylon and supports a card thickness of 0.062 inches (1.57mm). It operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with hairpin bellows contact type for secure mating
• Through-hole right-angle mounting with staggered solder termination
• Gold-plated phosphor bronze contacts ensuring corrosion resistance
• Polyamide insulation material rated for high-temperature environments

Edgeboard Connectors Applications

• High-density circuit board interconnections
• Industrial control system backplanes
• Telecommunications equipment modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix DHBT against official Sullins Connector Solutions documentation to confirm right-angle through-hole orientation and staggered termination style. Ensure compatibility with 0.062-inch card thickness and 0.050-inch pitch requirements. Cross-reference the 10.0µin gold plating specification to meet environmental durability standards. Confirm RoHS3 compliance status prior to integration into final assemblies.

Edgeboard Connectors Selection Notes

Select this model when right-angle PCB mounting is required for dual-edge card applications. The staggered solder termination facilitates automated assembly processes on standard manufacturing lines. The PA9T insulation provides necessary thermal stability for demanding operational environments. Verify that the 70-position density aligns with the target circuit board layout constraints.

Edgeboard Connectors Part Context

This component belongs to the GBB35 series of high-density card edge connectors from Sullins Connector Solutions. The series offers various mounting styles and termination options to accommodate different PCB design architectures. The GBB35DHBT specifically addresses needs for robust, right-angle connections in space-constrained electronic systems requiring reliable signal integrity.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include GBB35DHBR (through-hole straight) and GBB35DHFT (surface mount), provided the mounting orientation and termination method differences are accounted for in the design.
