305-046-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-268 is a standard card edge connector from the 305 Series, designed for dual-edge card applications. It features a 46-position configuration with a 3.96 mm pitch and supports a 1.57 mm board thickness. The connector utilizes a two-row arrangement with gold-plated copper alloy contacts rated for 5 A current. It employs a solder pin termination method and is constructed with a thermoplastic housing. Designed for vertical panel mounting, it operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact contact finish specifications and housing color variants. Ensure the selected part number matches the required board thickness tolerance of 1.57 mm. Confirm that the vertical panel mount orientation aligns with the mechanical design constraints of the target enclosure. Cross-reference the 46-position count with the PCB layout to prevent alignment errors during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required. The 46-position count suits applications needing moderate I/O density in a compact form factor. Verify compatibility with the target PCB's 1.57 mm thickness specification. Consider the 5 A current rating per contact for power distribution needs. Ensure the vertical mounting style fits the available panel space and access requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and mounting options for card edge applications. The series is characterized by its consistent 3.96 mm pitch and robust construction suitable for industrial environments. Similar parts in the series differ primarily in position count and specific mounting configurations while maintaining core electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and row configuration but different position counts, such as 305-040-520-268 or 305-054-556-278. Verify mechanical fit and electrical ratings before substitution. No alternative manufacturers are confirmed as direct replacements based on available data.
