305-020-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-020-521-208 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. This component features a dual-row configuration with 20 positions and a contact spacing of 3.96 mm (0.156 inches). It utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and employs a solder pin termination type for secure mounting.

Edgeboard Connectors Feature Summary

• Dual-row female connector design for high-density interconnect applications
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Vertical panel mount style ensures secure mechanical integration
• Thermoplastic insulator body offers structural stability and insulation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Medical equipment interfaces demanding reliable signal integrity
• Agricultural technology hardware operating in harsh environments
• Embedded system microcontroller peripheral expansion

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure requirements of the final assembly design.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge interface with 20 positions is required. The 3.96 mm pitch accommodates standard board layouts while maintaining signal separation. Consider the gold plating for environments where oxidation resistance is critical. The thermoplastic housing provides adequate insulation for general-purpose industrial voltage levels. Verify that the solder pin termination method matches the available PCB fabrication capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting options to suit different density requirements. EDAC designs these connectors for durability in demanding sectors such as medical and agricultural technologies. The 305-020-521-208 represents a specific configuration within this broader family, optimized for 20-position dual-row applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-040-520-268 and 305-048-521-208, though these feature higher position counts. Direct replacements must maintain the 20-position count and 3.96 mm pitch specification. Verify that any alternative part supports the same 1.57 mm board thickness and vertical mounting style.
