305-052-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-558 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 52 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold-plated copper alloy contacts and is constructed with a green thermoplastic polyester insulator body. The component supports a continuous current rating of 5 A and withstands 1800 VACrms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm plating thickness and material specifications. Confirm that the target application requires the 3.96 mm pitch and 52-position configuration. Ensure compatibility with the specified 1.57 mm board thickness. Check RoHS compliance status against project requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with 3.96 mm spacing is required. The 5 A current rating suits moderate power applications. The green insulator color aids in visual identification during assembly. Consider the low-profile design if vertical space constraints exist within the enclosure layout.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-052 variant specifically provides a 52-contact configuration. The product line is engineered for reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 Series for alternative position counts. Verify that substitute components maintain the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure electrical ratings meet or exceed the original 5 A and 1800 VACrms specifications.
