305-052-555-204

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-204 is a standard card edge connector from the 305 Series, designed for dual female termination with 52 positions. It features a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component utilizes gold-plated copper alloy contacts with a 10.0µin (0.25µm) plating thickness and employs solder lug end-type termination. Constructed with a green thermoplastic polyester insulator, it supports a current rating of 5A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female configuration providing 52 connection points for board-to-board or backplane interfaces
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Low profile insulator body design accommodates standard 0.062 inch PCB thickness
• Solder lug termination facilitates secure panel mounting and robust electrical connections

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment utilizing standard card edge form factors
• Test and measurement instrumentation panels
• Computing hardware peripheral interface modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating specifications, and mechanical dimensions. Ensure compatibility with the target PCB thickness of 0.062 inches and validate that the 5A current rating meets system requirements. Confirm RoHS compliance status and check for any series-specific variations in flange characteristics or insulation material properties before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 52-position card edge connector is required for vertical panel installation. The 3.96mm pitch is suitable for applications needing robust signal integrity with gold-plated contacts. Consider the 5A current rating and -40°C to +105°C operating range for environmental suitability. Ensure the design accommodates the solder lug termination style and the specified PCB thickness constraint for proper mechanical fit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and configurations, all sharing common mechanical and electrical standards such as the 0.156-inch pitch and gold-plated contact options. The 305-052-555-204 specifically represents a high-density dual-row variant optimized for reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series variants like 305-052-520-201 or 305-052-556-502 for similar specifications. Verify that substitute parts match the 52-position count, 0.156-inch pitch, and dual female configuration. Ensure identical PCB thickness acceptance and current ratings to maintain system integrity without redesign.
