305-022-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-208 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card types. The connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current, it accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, providing durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, termination style, and insulation material properties. Ensure compatibility with required polarizing key configurations before procurement. Cross-reference datasheet specifications for mechanical dimensions and electrical ratings to prevent integration errors in final assembly designs.

Edgeboard Connectors Selection Notes

Select this model when a 22-position dual-edge interface is required with a 3.96 mm pitch. Confirm that the target circuit board thickness falls within the 1.37 mm to 1.78 mm acceptance range. Verify that the application environment remains within the specified -40°C to +105°C operational limits and requires a 5 A current rating.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent 3.96 mm spacing. These connectors are engineered for high-reliability applications requiring robust mechanical retention and stable electrical performance across diverse industrial environments.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for direct equivalents. Verify that any alternative maintains identical 3.96 mm pitch, 22-position count, and dual-edge female configuration. Ensure mechanical mounting styles and thermal ratings match original requirements.
