395-020-521-404

Edgeboard Connectors Overview

The EDAC Inc. 395-020-521-404 is a single edge female card edge connector designed for reliable signal communication and power connections. It features 20 positions with a contact spacing of 0.100 inches (2.54 mm) and a row spacing of 0.200 inches (5.08 mm). The connector utilizes gold-plated contacts to ensure low resistance and durability. It is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), providing a secure mechanical interface for mother, daughter, and extender board applications.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm pin count, termination type, and plating specifications. Ensure compatibility with the target PCB thickness and mating connector requirements. Request manufacturer datasheets for precise mechanical drawings and environmental ratings before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a single-row female connector is required for 0.062-inch thick PCBs. The 20-position layout suits moderate I/O density needs. Verify that the 0.100-inch pitch aligns with the system's board design rules and mating hardware constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 395 series of card edge connectors. The series is characterized by quality engineering solutions for interconnecting electronic modules. These connectors are widely used in industrial and commercial electronics where reliable physical and electrical connections between stacked or adjacent circuit boards are essential.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 395 series family. Single edge variants with matching position counts and pitch dimensions may serve as alternatives. Confirm identical mechanical tolerances and contact plating specifications to maintain system integrity.
