305-046-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-268 is a standard card edge connector featuring 46 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. The contacts are gold-plated copper alloy, rated for 5 A current with 5 GOhms insulation resistance. Designed for panel mounting at a vertical angle, the housing is green thermoplastic. Operating temperatures span from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact pin count and termination type. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the vertical panel mount orientation aligns with the mechanical assembly requirements. Check RoHS compliance status if restricted substances are a project constraint.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 46-position layout suits applications needing moderate I/O density. Verify that the 5 A current rating meets the electrical load requirements. Consider the green thermoplastic housing material for environmental durability within the specified temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305 series is designed for general-purpose electronic interconnections. It provides a robust solution for connecting printed circuit boards in modular systems.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC catalog for direct substitutes with identical pitch and row configuration. Verify mechanical dimensions and contact plating specifications before substitution. Generic equivalents may not match the precise thermal or electrical ratings.
