Edgeboard Connectors Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact physical dimensions and termination compatibility. Ensure that the locking feature aligns with the target assembly requirements. Cross-reference the gold plating specifications with environmental compliance standards such as RoHS before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a 0.125-inch pitch is required for high-current or high-reliability applications. The wire wrap termination suits environments where vibration resistance is critical. Compare against standard press-fit alternatives if solderless installation is preferred. Confirm that the polyamide insulation meets thermal requirements for the operating environment.

Edgeboard Connectors Part Context

This component belongs to the GMA series of card edge connectors from Sullins Connector Solutions. The series is designed for demanding industrial and commercial applications. The GMA variant specifically emphasizes durability through its locking design and robust contact structure, distinguishing it from non-locking counterparts in the broader product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other Sullins models with identical 56-pin counts and 0.125-inch pitch. Verify that replacement parts maintain the same wire wrap termination and locking mechanism to ensure mechanical compatibility.
