Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the panel mount requirement aligns with the mechanical design constraints of the final assembly enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with 56 positions is required for panel-mounted architectures. The 3.96 mm pitch suits applications needing wider spacing between conductors. Verify that the 5 A current rating meets the electrical load requirements of the connected circuits. Ensure the operating temperature range covers the environmental conditions of the intended deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options for diverse industrial needs. The 305-056-500-204 specifically addresses the need for a mid-range position count with durable gold contacts. It represents a standardized solution for connecting double-sided edge-board designs in professional electronics assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference the 305-056-500-204 with other EDAC 305 series variants such as the 305-054-556-278 or 305-048-500-558 if position count adjustments are permissible. Verify that any substitute maintains the identical 3.96 mm pitch and 1.57 mm board thickness tolerance to ensure mechanical fit without modification.
