305-082-521-212

Edgeboard Connectors Overview

The EDAC Inc. model 305-082-521-212 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 82 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 a green thermoplastic polyester insulator body. Rated for 5 A current, it supports panel mount vertical installation with solder pin termination.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material composition as defined by the manufacturer. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before procurement. Confirm that the panel mounting style aligns with the mechanical constraints of the assembly enclosure. Cross-reference the 82-position count against schematic requirements to prevent mismatched connectivity.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required with a 3.96 mm pitch. The 5 A current rating suits moderate power distribution applications. Verify that the vertical panel mount orientation fits the system layout. Consider the green insulator color for visual identification if required by assembly standards. Ensure the solder pin termination method matches the available PCB fabrication capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts while maintaining consistent 0.156 inch spacing. The 305-082-521-212 variant specifically addresses higher density needs within this family, providing 82 connection points in a dual-row configuration suitable for complex signal routing.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 82 positions and 3.96 mm spacing, such as 305-082-520-212 variants. Verify mechanical dimensions and electrical ratings before substitution. Generic equivalents may lack the specific low-profile body or gold plating specifications.
