305-040-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 40 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector supports a nominal printed circuit board thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A current. It utilizes a solder lug termination type and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density interconnects
• Gold-plated copper alloy contacts for reliable conductivity
• Panel-mount design with vertical installation angle
• Compatible with standard 0.062 inch thick PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Automotive electronic module connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure correct contact plating thickness and housing color options. Confirm that the target application requires a dual-edge female connector compatible with 0.062 inch boards. Check RoHS compliance status against regional regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-row interface is required with a 3.96 mm pitch. Ensure the mechanical design accommodates panel mounting and vertical alignment. Verify that the PCB stack-up allows for the specified 1.57 mm thickness tolerance. Consider the 5 A current rating for power distribution needs within the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting styles and position counts. The series is characterized by its thermoplastic insulator body and standardized dimensions for interchangeability. It serves as a reliable solution for connecting double-sided edge cards in modular electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-040-556-502 and 305-040-556-512, differing primarily in housing color or minor packaging variations. Cross-brand replacements require verification of pitch, row spacing, and PCB thickness compatibility.
