GMM44DSEN

Edgeboard Connectors Overview

The GMM44DSEN is an 88-position female card edge connector manufactured by Sullins Connector Solutions. It features a dual-edge configuration with two rows of 44 contacts each, designed for non-specified double-sided PCBs. The connector utilizes phosphor bronze contacts with a gold plating finish and a 0.156-inch (3.96mm) pitch. It supports a board thickness of 0.062 inches (1.57mm) and employs a through-hole right-angle mounting style. The housing is constructed from black polyamide (PA9T) nylon, ensuring operation within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for double-sided PCB integration
• Through-hole right-angle mounting for secure board attachment
• Gold-plated phosphor bronze contacts for reliable signal transmission
• Polyamide insulation material rated for high-temperature environments

Edgeboard Connectors Applications

• Double-sided printed circuit board interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against official Sullins documentation to confirm flange characteristics and mounting orientation. Ensure compatibility with the target PCB thickness of 0.062 inches and verify that the right-angle through-hole termination aligns with the assembly process requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector is required for double-sided boards with a 0.156-inch pitch. Confirm that the right-angle through-hole mounting fits the mechanical constraints. Verify that the operating temperature range and insulation material meet the environmental conditions of the intended application.

Edgeboard Connectors Part Context

This part belongs to the GMM44 series of female card edge connectors from Sullins Connector Solutions. The series offers various mounting styles and flange options. The GMM44DSEN specifically denotes a dual-edge, right-angle through-hole variant with standard flange features, distinct from panel mount or single-row configurations available in the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GMM44DSAN and GMM44DSAS, which share identical electrical specifications and form factor but may differ in flange design or packaging. Verify mechanical fit and pinout compatibility before substitution.
