737-026-520-101

Edgeboard Connectors Overview

The EDAC Inc. 737-026-520-101 is a standard card edge connector receptacle designed for press-fit installation. It features 26 positions in a single row with a 3.96 mm pitch, accommodating board thicknesses from 1.37 mm to 1.78 mm. The contacts are gold-plated copper alloy, rated for 3 A current and 5 GOhms insulation resistance. Operating within -40°C to +105°C, it utilizes a thermoplastic polyester housing.

Edgeboard Connectors Feature Summary

• Press-fit termination method ensures secure mechanical attachment without soldering.
• Gold-plated copper alloy contacts provide reliable electrical conductivity and corrosion resistance.
• Vertical mounting orientation supports direct perpendicular PCB integration.

Edgeboard Connectors Applications

• High-reliability industrial control systems
• Telecommunications infrastructure equipment
• Aerospace and defense avionics modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact contact plating, housing material, and termination style compatibility. Ensure that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper engagement and mechanical stability during press-fit assembly processes.

Edgeboard Connectors Selection Notes

Select this component when a robust, non-soldered connection is required for high-vibration environments. The vertical profile and press-fit design simplify assembly while maintaining signal integrity. Confirm that the application demands a single-row interface with a 3.96 mm spacing to match the existing board layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 737 series of standard card edge connectors. The series offers various position counts and termination options, providing modular solutions for diverse electronic interconnect needs. The 737-026 variant specifically addresses applications requiring moderate density connections with durable press-fit capabilities.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference lists for verified substitutes. Generic equivalents may not match the precise press-fit force requirements or dimensional tolerances necessary for reliable operation in critical systems.
