305-052-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-052-500-203 is a standard card edge connector from the 305 series, designed for dual female board-to-board or panel mounting applications. It features 52 positions with a contact spacing of 0.156 inches (3.96 mm) and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual female configuration with half-bellows contact type for secure card retention
• Flush mount flange with floating bobbin design for alignment tolerance
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester insulation provides stability across specified operating temperatures

Edgeboard Connectors Applications

• Panel-mounted interface connections for electronic modules
• Edgeboard interconnects in industrial control systems
• Signal routing between backplanes and daughter cards
• High-density I/O connections in telecommunications equipment

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 of 1.57 mm to ensure proper mechanical fit. Check for RoHS3 compliance requirements if environmental regulations apply to the end product. Ensure the flush mount style with floating bobbin aligns with the chassis design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel installation. The 52-position capacity suits high-density signal applications. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. The gold plating offers durability for repeated insertion cycles compared to tin variants.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, including vertical and straight configurations. The 305-052-500-203 specifically denotes a dual female, flush-mount variant with gold contacts, distinguishing it from single-row or different pitch alternatives within the broader family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the 3.96 mm pitch and 52-position count. Verify identical flange dimensions and floating bobbin specifications for direct mechanical substitution. Ensure current ratings and temperature ranges meet or exceed original design requirements.
