305-018-556-502

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-502 is a dual-edge female card edge connector designed for board-to-board or backplane interconnections. It features 18 positions with a 0.156-inch (3.96 mm) pitch and supports PCB thicknesses of 0.054 to 0.070 inches. The contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. This component utilizes a solder termination method and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure card insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Solder termination for stable PCB mounting
• Thermoplastic polyester insulation for durability

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Computer peripheral interfaces
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating and termination style. Confirm that the required PCB thickness falls within the specified 0.054 to 0.070-inch range for proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to your assembly process.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with a 3.96 mm pitch is required. Ensure the mating card meets the specified thickness tolerance. Consider the operating temperature range and current rating requirements relative to the application's electrical load. Verify panel mount compatibility if used in chassis-based designs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles to accommodate different design needs. The 305-050-556-502 variant shares similar structural characteristics but differs in position count. The series is widely used in modular electronic systems requiring robust interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching pitch and position counts, such as 305-018-556-558. Cross-manufacturer replacements require verification of pitch, contact configuration, and mounting dimensions to ensure mechanical and electrical compatibility.
