305-086-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-086-520-503 is a standard card edge connector receptacle featuring 86 positions with a 3.96 mm pitch and dual-row configuration. It accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are gold-plated copper alloy, rated for 5 A current, and utilize solder pin termination. Designed for panel mount installation at a vertical angle, the housing is green thermoplastic polyester. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two-sided PCB traces
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount orientation facilitates structured chassis integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact plating thickness and housing color variations. Ensure the target PCB thickness matches the 1.57 mm specification to guarantee proper mechanical retention and electrical contact stability during operation.

Edgeboard Connectors Selection Notes

Select this component when high-density connections are required within a constrained vertical space. The 3.96 mm pitch allows for substantial trace routing on the host board while maintaining compatibility with standard industrial form factors. Verify that the 5 A current rating aligns with the power distribution requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing modular solutions for electronic assemblies. The 305-086 variant specifically addresses applications requiring higher I/O density compared to lower-position counterparts in the same family.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part number 305-086-500-201 for similar specifications. Confirm that alternative suppliers offer identical 3.96 mm pitch and 1.57 mm board thickness compatibility to ensure mechanical interchangeability without redesigning the host PCB footprint.
