305-064-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 64 positions 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), falling within an operational range of 0.054 to 0.070 inches. It utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) finish and employs a half-crimped termination type. Rated for 5 A current, it operates between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified board types
• Gold-plated copper alloy contacts with half-crimped termination
• Low-profile insulator body constructed from thermoplastic polyester
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement instrumentation interfaces
• Automotive electronics modules needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct flange and mounting hardware specifications. Confirm that the target PCB thickness aligns with the 0.054 to 0.070 inch acceptance range. Check RoHS compliance status and REACH restrictions prior to final integration. Ensure the selected variant matches the required panel cutout dimensions for proper flush installation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge configuration with 64 positions is required for panel-mount applications. The 3.96 mm pitch suits designs needing wider spacing for high-current or high-voltage isolation. Consider the 1.57 mm nominal board thickness compatibility during mechanical design. Evaluate the need for threaded versus unthreaded flange options based on enclosure vibration requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are engineered for durability in demanding environments. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 305-064-521-568 specifically addresses applications requiring a high-density dual-edge interface with secure panel mounting capabilities.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series cross-reference documentation for direct substitutes. Verify that alternative parts match the 0.156 inch pitch and 64-position count. Ensure replacement components support the same 0.062 inch nominal board thickness and panel mount form factor.
