305-052-520-204

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-204 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual female configuration with 52 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm (0.054" to 0.070"). Contacts are constructed from copper alloy with gold plating and employ a half-beamlock termination type via solder pins. The housing is made of green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides robust signal connectivity for double-sided card edge boards.
• Half-beamlock contact design ensures secure mechanical retention and reliable electrical performance during insertion.
• Vertical panel mount style facilitates direct integration into chassis or enclosure structures.
• Gold-plated copper alloy contacts offer corrosion resistance and stable conductivity over the specified temperature range.

Edgeboard Connectors Applications

• Industrial control systems requiring durable interconnects
• Telecommunications equipment utilizing standard card edge modules
• Automotive electronics assemblies needing high-reliability connections
• Test and measurement instrumentation hardware

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 52-position count and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB thickness within the 1.37 mm to 1.78 mm range. Ensure the vertical panel mount orientation aligns with the system enclosure design. Check for RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the gold plating specification against environmental exposure conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 52-position interface is necessary for vertical panel installation. The 3.96 mm pitch dictates the corresponding trace spacing on the mating card edge. Consider the half-beamlock termination for applications requiring secure solder joint integrity. Evaluate the thermoplastic polyester housing material against thermal management needs within the -40°C to +105°C operational window. Ensure the green color coding meets any visual identification protocols in use.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which encompasses various standard card edge connectors. The series offers multiple position counts and row configurations to suit different interface densities. The 305-052 variant specifically addresses higher-density requirements within the standard pitch family. Similar parts in the series may differ in position count, termination style, or housing color while maintaining consistent mechanical interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 52-position count, 3.96 mm pitch, and dual female configuration. Verify that alternative components support the same vertical panel mount orientation and half-beamlock termination type. Ensure replacement housings accommodate the identical 1.37 mm to 1.78 mm board thickness range. Confirm that contact materials and plating meet or exceed the original gold-on-copper-alloy specifications for equivalent performance.
