- Industrial control module interfaces
- Telecommunications hardware assembly
Procurement Notes
Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, material composition, and mechanical tolerances. Ensure compatibility with target PCB dimensions and mating connector specifications before procurement. Cross-reference part numbers with authorized distributors to validate current availability status and compliance certifications.
Selection Notes
Select this connector when a 20-position interface with 3.96 mm spacing is required for vertical panel installation. Confirm that the application environment remains within the operational temperature limits defined by the manufacturer. Evaluate mechanical stress requirements to ensure the thermoplastic housing provides adequate insulation resistance and durability for the intended service life.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting configurations tailored for diverse electronic applications. The 306 series emphasizes robust construction and precise alignment features to maintain consistent electrical connectivity in demanding industrial and commercial environments.
Replacement Considerations
Consult official EDAC substitution guides for verified alternative part numbers. Do not assume cross-compatibility with generic card edge connectors without verifying pinout, pitch, and mechanical fit parameters.
