Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact flange dimensions and termination style compatibility. Ensure that the target printed circuit board thickness aligns with the specified 1.57 mm requirement for proper mechanical engagement. Confirm RoHS compliance status through the latest supplier documentation before final procurement authorization.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 28-position count suits moderate-density interconnect needs. Verify that the vertical installation angle and solder pin termination method match the assembly process requirements. Consider the M3 threaded insert feature if secure panel fixation without additional hardware is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust industrial environments. The series typically supports various position counts while maintaining consistent electrical characteristics. The 305-028-520-507 variant specifically addresses applications requiring dual-row connectivity with panel-mounting capabilities and high-current handling.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-018-520-507 or 305-038-520-507 for different position counts. Verify identical pitch, flange type, and termination style before substitution. No direct third-party substitutes are confirmed in public documentation.
