Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm flange characteristics and mounting style, as variations exist within the 305 series. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical engagement. Check RoHS compliance status against project requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the application environment remains within the -40°C to +105°C operational temperature range. Verify that the 5 A current rating per contact aligns with the electrical load requirements of the connected circuitry.

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 options, utilizing thermoplastic insulators and gold-plated contacts. The 305-052-521-507 specifically addresses needs for 52-position dual-edge interfaces in industrial and telecommunications hardware.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 52 positions and 3.96 mm pitch, such as 305-052-521-502 or 305-052-521-508, provided flange features are compatible.
