Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness, housing color, and flange dimensions. Ensure the target application matches the specified 3.96 mm pitch and compatible PCB thickness range. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 56 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing between contacts compared to finer pitches. Verify that the thermal environment stays within the -40°C to +105°C operational limits. Ensure the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm tolerance for proper engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems.
