305-066-520-558

Edgeboard Connectors Overview

The EDAC 305-066-520-558 is a standard card edge connector from the 305 series, designed for dual-row applications. It features 66 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts plated in gold, it provides a continuous current rating of 5 A. The housing is made of thermoplastic polyester, offering an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with low-profile insulator body
• Accepts polarizing keys between or within contacts
• Gold-plated copper alloy contacts for reliable conductivity
• Vertical panel mount installation style

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing high-density I/O
• Computer peripheral devices with vertical mounting constraints

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row spacing against the target PCB design before ordering. Confirm that the mating card edge thickness aligns with the 1.57 mm specification. Ensure the application environment stays within the specified temperature range. Check for any required accessory keys if polarization is needed. Consult official datasheets for detailed mechanical dimensions and soldering profiles.

Edgeboard Connectors Selection Notes

Choose this model when a dual-row interface with 3.96 mm pitch is required. It is suitable for applications demanding a 5 A current rating per contact. Select this variant for vertical panel mounting rather than PCB surface mount. Consider the gold plating for corrosion resistance in harsh environments. Verify compatibility with existing polarizing key systems if signal isolation is critical.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various position counts and mounting options. The series is characterized by its standardized 3.96 mm contact spacing and durable construction. Similar models in the series include different pin counts such as 305-020-520-558 or 305-048-520-558, sharing identical electrical and mechanical specifications except for the number of positions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-066-520-201 or other suffix variations if different plating or material properties are required. Cross-brand replacements must match the 3.96 mm pitch, 66-position count, and 1.57 mm board thickness. Verify that alternative connectors support the same 5 A current rating and voltage insulation requirements.
