305-068-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-068-556-508 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 68 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, while the housing is constructed from thermoplastic material. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Metal-to-metal contact system ensures ultra-reliable interconnections
• Dual female design accommodates double-sided card edges
• Gold-plated contacts provide corrosion resistance and low contact resistance

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high reliability
• Industrial control systems utilizing double-sided circuit boards
• Rack and panel interconnection environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating and termination specifications. Ensure compatibility with the target PCB thickness within the 1.37 mm to 1.78 mm range. Confirm that the 3.96 mm pitch aligns with the design requirements. Check for RoHS compliance status if required by project regulations. Validate availability through authorized distributors as supply may be limited.

Edgeboard Connectors Selection Notes

Select this component when a robust, panel-mount solution is needed for double-sided cards. The 68-position count suits moderate-density applications. Verify that the vertical installation style fits the mechanical constraints. Consider the 5 A current rating for power distribution needs. Ensure the thermoplastic housing material meets environmental requirements for the intended operating temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for different connectivity needs. The 305 series is characterized by its durability and suitability for harsh industrial environments. It serves as a critical interface between circuit boards and panel-mounted systems.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative position counts or configurations. Direct substitutes must match the 3.96 mm pitch and dual female layout. Verify mechanical dimensions and mounting hole patterns before substitution.
