Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 26-position count and 3.96 mm pitch before ordering. Confirm that the panel mounting style and vertical orientation align with the mechanical design constraints of the target enclosure. Ensure that the solder lug termination method is compatible with the assembly process used in the manufacturing line. Check RoHS compliance status if environmental regulations apply to the final product deployment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating suits moderate power distribution needs alongside signal transmission. Consider the vertical mounting angle and solder lug termination for PCB layout compatibility. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for robust industrial environments. The series offers various position counts and mounting options to accommodate different board sizes and structural requirements. The 305-026 variant specifically addresses applications requiring a compact dual-edge interface with high durability and consistent electrical performance over time.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 26-position counts and 3.96 mm pitch, such as the 305-026-520-268 or 305-026-520-558, provided the flange and termination specifications are verified for mechanical interchangeability.
