305-064-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-278 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 64 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are gold-plated copper alloy with a half-bead type, rated for 5 A current. The insulator body is made of thermoplastic polyester, offering a low-profile design suitable for vertical installation.

Edgeboard Connectors Feature Summary

• Dual-row female connector structure with gold-plated contacts for reliable signal transmission
• Low-profile insulator body designed for vertical panel mounting applications
• Accepts standard 0.062 inch nominal thickness PCBs with specified board thickness range
• Thermoplastic polyester housing providing structural integrity and environmental resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interconnects
• Communication equipment utilizing standard form factor circuit boards
• Consumer electronics assemblies needing high-density vertical connections
• Medical device hardware with specific thermal and mechanical requirements

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to procurement. Ensure storage conditions maintain material integrity given the thermoplastic composition. Check for any specific handling instructions related to the gold-plated contact surfaces to prevent contamination during assembly processes.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 64-position interface is required for 0.156-inch pitch applications. Verify that the target PCB thickness falls within the acceptable range for proper contact engagement. Consider the vertical panel mount orientation and low-profile height constraints against enclosure specifications. Ensure the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and configurations to support different board densities. As an edgeboard connector, it provides a secure mechanical and electrical interface between the connector header and the peripheral circuit card, ensuring stable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching pin counts and pitch, such as 305-064-520-268 if non-gold plating is acceptable. Cross-reference with 315-064-521-278 for similar specifications within the extended temperature or feature set family. Verify dimensional compatibility and mounting hole alignment before substituting.
