305-050-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-578 is a standard card edge connector featuring 50 positions arranged in a dual configuration with a 3.96 mm (0.156 inch) pitch. It utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Designed for panel mounting via through-hole solder pins, this component supports printed circuit boards with thicknesses ranging from 1.37 mm to 1.78 mm. The connector provides a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage across the specified operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge applications
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulator body offers durability and thermal stability
• Panel mount design with integrated flange features for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing high-reliability connections
• Automotive electronics assemblies demanding stable electrical performance

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position dual configuration and 3.96 mm pitch before ordering. Confirm compatibility with the target printed circuit board thickness within the 1.37 mm to 1.78 mm range. Ensure the application environment remains within the specified -40°C to +105°C operating temperature limits. Check for any regional distribution restrictions or supply chain constraints associated with the manufacturer. Validate that the gold plating thickness meets the requirements for the intended electrical interface longevity.

Edgeboard Connectors Selection Notes

Select this connector when a dual-sided card edge interface with a 3.96 mm spacing is required. Consider the 5 A current rating and 1800 VACrms insulation capability for high-power or high-voltage circuits. Choose the panel mount style if mechanical stability and alignment are critical for the assembly. Evaluate the thermoplastic polyester material properties against environmental exposure conditions. Compare the physical dimensions and flange characteristics with existing chassis designs to ensure proper fit.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are designed for general-purpose electronic interconnections. The series offers various position counts and configurations to accommodate different circuit board densities. The 305-050-520-578 specifically addresses applications requiring a 50-pin dual interface with robust mechanical retention. It represents a standardized solution for connecting double-sided edge cards in industrial and commercial hardware environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-048-520-578 and 305-038-520-502, though these differ in position count. Verify that alternative parts maintain the identical 3.96 mm pitch and dual female contact type. Ensure replacement components support the same PCB thickness range and mounting style. Confirm that electrical ratings such as current and voltage withstand capabilities remain consistent with the original specification.
