Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact termination style and flange configuration before procurement. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the required polarizing key specifications match the connector's acceptance capabilities. Cross-reference the manufacturer datasheet for precise dimensional tolerances and environmental operating limits.

Edgeboard Connectors Selection Notes

Select this model when a vertical panel mount solution is required for double-sided edge cards. The 3.96 mm pitch accommodates standard board layouts while maintaining a compact profile. Consider the 5 A current capacity for power distribution needs within the interface. Verify that the thermoplastic housing meets the necessary temperature ratings for the intended operational environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options for diverse industrial applications. The 305-028 variant specifically addresses requirements for moderate density connections with reliable mechanical retention. It shares common design characteristics with other parts in the family, such as consistent pitch and housing materials.

Edgeboard Connectors Replacement Considerations

Direct substitutes include the 305-028-555-508 and 305-028-555-568 variants. These alternatives share identical electrical and mechanical specifications but may differ in termination style or flange threading. Verify that any replacement part maintains the same 28-position count and 3.96 mm pitch to ensure board compatibility.
