305-048-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-558 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 48 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm (0.054" to 0.070"). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified card types
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount installation style with vertical orientation
• Thermoplastic polyester insulator providing stable performance across wide temperature ranges

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-reliability signal connections
• Automotive electronics modules operating within specified thermal limits

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 521-558 corresponds to the required contact finish and housing color specifications. Confirm compatibility with the target PCB thickness range of 1.37mm to 1.78mm. Ensure panel cutout dimensions align with the connector's mechanical footprint. Check for RoHS compliance requirements if applicable to the end product. Validate that the 5A current rating meets the circuit's electrical demands under all operating conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 48-position interface is required for panel-mounted installations. The 3.96mm pitch is suitable for applications not demanding high-density routing. Consider the gold contact finish for environments where oxidation resistance is critical. The vertical mounting style simplifies integration into chassis designs. Evaluate the thermal range against the operational environment to ensure long-term reliability without derating.
