305-068-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 68 positions and a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The unit offers a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual female contact configuration ensures reliable signal transmission
• Gold-plated copper alloy contacts provide corrosion resistance and conductivity

Edgeboard Connectors Applications

• Medical interconnect systems requiring durable connections
• Agricultural technology equipment operating in harsh environments
• Industrial control panels utilizing card edge modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and insulation material properties. Confirm that the required polarizing key type matches the connector's acceptance specifications. Ensure the target PCB thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Cross-reference the 68-position count with system design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density 68-position interface is required for panel-mounted vertical installations. The 0.156-inch pitch accommodates standard double-sided card edges. Consider the 5 A current rating and 1800 VACrms insulation capability for power and signal integrity needs. Verify compatibility with existing polarizing key strategies if positional locking is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, characterized by green thermoplastic polyester insulation and half-beam contacts. The series provides various position counts while maintaining consistent 3.96 mm spacing. The 305-068 variant specifically addresses higher channel density requirements within the same mechanical footprint constraints as lower-count models.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Verify that alternative parts maintain the 0.156-inch pitch and dual female configuration. Ensure replacement components support the same 5 A rating and 1800 VACrms dielectric strength.
