305-080-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-080-521-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 80 positions arranged in two rows 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), within an operational range of 0.054 to 0.070 inches. It utilizes female contacts made of copper alloy with gold plating, rated for 5 A continuous current. The unit employs a solder pin termination style for panel mounting.

Edgeboard Connectors Feature Summary

• Dual-row female configuration supporting non-specified dual-edge card insertion
• Low-profile insulator body constructed from green thermoplastic polyester
• Semi-beam spring contact design ensuring reliable electrical engagement
• Panel mount installation with flange features including top opening and threaded inserts

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device internal module connections
• Consumer electronics assembly interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 80-position dual-row configuration and 3.96mm pitch before ordering. Confirm compatibility with the target PCB thickness of 1.57mm nominal. Ensure the gold-plated copper alloy contacts meet the necessary corrosion resistance requirements for the intended environment. Check RoHS compliance status if restricted substances are prohibited in the final assembly. Validate that the panel mounting flange dimensions align with the mechanical enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a robust dual-edge connector with high current capacity is required. The 5A rating supports significant power distribution needs compared to lower-rated alternatives. The semi-beam contact type offers superior retention force for heavy cards. Consider the vertical orientation and panel mount style for fixed infrastructure applications rather than portable devices. The green insulator provides visual identification within complex assemblies.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in card edge connectors for demanding environments. The series offers various position counts and mounting options while maintaining consistent 3.96mm pitch standards. The 305-080 variant specifically addresses high-density interface requirements with its 80-position layout. EDAC designs these connectors to withstand harsh industrial conditions, ensuring long-term reliability in critical systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 80-position dual-row specifications and matching 3.96mm pitch. Verify that any alternative maintains the same 5A current rating and gold-plated contact finish. Cross-reference mechanical drawings to ensure flange dimensions and panel cutout requirements remain compatible with existing hardware.
