305-068-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-208 is a standard card edge connector from the 305 Series, designed for panel mounting applications. It features a dual-edge female configuration with 68 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Constructed with copper alloy contacts finished with gold plating, it offers a current rating of 5 A. The housing is made of green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific ordering suffix matches the required pin count and termination style. Ensure environmental specifications align with operational requirements, particularly regarding temperature range and material composition. Check for updated regulatory compliance status such as RoHS3 certification before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a high-density interface with a 3.96 mm pitch is required for panel-mounted assemblies. The dual-edge design accommodates standard double-sided circuit boards within the specified thickness tolerance. Consider the 5 A current rating and gold contact finish for applications demanding robust electrical performance. Verify that the vertical panel mount footprint integrates correctly with the enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series provides various position counts and termination options for diverse electronic interconnection needs. The 305-068 variant specifically addresses applications requiring 68 connection points in a compact dual-row layout. It represents a standardized solution for reliable board-to-panel connectivity in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series connectors with matching 68-position configurations and 3.96 mm pitch. Verify compatibility by comparing mechanical dimensions, contact plating, and insulation material properties. Alternative manufacturers may offer similar specifications, but ensure exact fitment for panel mounting holes and card edge thickness tolerances.
