305-040-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-204 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy and gold-plated to ensure reliable signal transmission, supporting a current rating of 5 A. The insulator body is made of thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two-sided PCB contacts
• Low-profile insulator body constructed from thermoplastic material
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing reliable high-density interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact contact termination type and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the panel mount requirements align with the vertical installation angle specified for this component series.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 40-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications where standard spacing is preferred over finer pitches. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry before finalizing the design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options, providing flexibility for different board densities. The 305-040 variant specifically addresses designs requiring forty connection points in a compact dual-row format suitable for industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include part numbers such as 305-040-520-204 or 305-040-520-268, which share identical positioning and pitch but may differ in termination style or packaging. Cross-reference the datasheet to ensure mechanical and electrical equivalence.
