305-084-520-268

Edgeboard Connectors Overview

The EDAC Inc. model 305-084-520-268 is a standard card edge connector designed for dual-edge board insertion. It features 84 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). It utilizes gold-plated copper alloy contacts and a low-profile insulator body.

Edgeboard Connectors Feature Summary

• Dual-edge female connector configuration for secure board retention
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body design minimizes vertical space requirements

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Medical device internal module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating thickness and material specifications. Ensure the target application PCB thickness aligns with the 0.062-inch nominal requirement for proper mechanical engagement. Cross-reference the pin count and series designation to avoid substitution errors within the 305 family.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 84 positions is required. The 0.156-inch pitch accommodates standard board layouts while maintaining robust electrical performance. Consider the panel mount style and vertical orientation during mechanical integration planning to ensure adequate clearance for mating operations.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles tailored for industrial and commercial applications. The 305 series is characterized by its durable construction and consistent electrical characteristics across different configurations.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 series ordering guide for verified substitute part numbers. Direct replacements must match the 84-position count, 0.156-inch pitch, and dual-edge configuration. Verify that any alternative maintains the same panel mount style and vertical orientation.
