305-064-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-064-520-278 is a standard card edge connector from the 305 series, designed for panel mount applications with through-hole solder termination. It features 64 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The housing is made of green thermoplastic material, providing structural integrity and insulation. This component supports board thicknesses within specified mechanical limits and operates reliably across a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edge PCBs for increased I/O density.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance.
• Panel mount installation style with vertical orientation ensures secure mechanical fixation.
• Thermoplastic insulator housing offers durability and compliance with industrial environmental standards.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing double-sided circuit boards
• Test and measurement instrumentation interfaces
• Medical device hardware connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, contact finish, and housing color specifications. Ensure compatibility with target PCB thickness and panel mounting requirements before procurement. Confirm RoHS compliance status via current manufacturer datasheets as regulatory updates may occur.

Edgeboard Connectors Selection Notes

Select this model when a high-position-count, dual-row card edge connector is required for panel-mount applications. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches, aiding in manufacturing yield. Verify that the target application environment falls within the -40°C to +105°C operating temperature range and that the mechanical load on the connector is within rated limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in general-purpose electronic assemblies. The series offers various position counts and configurations to suit different interface needs. The 305 series is characterized by its durable thermoplastic construction and reliable solder pin termination, making it suitable for demanding industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 64-position dual-row specifications, such as 305-064-520-268 or 305-064-520-208, provided housing color and specific contact finish variations align with system requirements. Cross-brand replacements must match the 3.96 mm pitch, dual-edge geometry, and panel-mount form factor precisely.
