• High-density signal routing systems

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct flange and termination specifications. Confirm RoHS compliance status and environmental classifications such as MSL rating prior to integration. Cross-reference the part number with the latest datasheet to validate material composition and dimensional tolerances for your specific assembly requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 66-position connection is required with a 3.96 mm pitch. Ensure the host PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the straddle mount style for panel installation needs and verify that the 5 A current rating meets the circuit load requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common electrical ratings and contact materials. The 305-066 variant specifically addresses higher density applications requiring robust mechanical retention and consistent electrical performance across industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange configurations. Verify compatibility with existing polarizing key systems before substituting.
