• Provides 1800 VACrms dielectric voltage withstand capability
• Features half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Communication equipment backplanes
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pin count, contact plating, and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and production batch.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 3.96 mm pitch is required. Ensure the PCB thickness falls within the 1.37 mm to 1.78 mm range. Verify that the application environment supports the specified temperature range and current rating without additional derating.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors. The series offers various position counts and configurations for standard board interfaces. The 305 series is characterized by its robust construction and compatibility with polarizing keys, distinguishing it from lower-cost alternatives.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 80-position dual configurations. Cross-brand replacements require verification of pitch, board thickness tolerance, and contact material specifications to maintain mechanical and electrical integrity.
