305-018-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-507 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features an 18-position dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a maximum board thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C. It provides a continuous current rating of 5 A and utilizes gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density interconnect applications
• Gold-plated mating area ensures low contact resistance and durability
• Panel mount installation style with vertical orientation for secure housing
• Compatible with between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Automotive electronics sub-assemblies

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before ordering. Confirm that the PCB design accommodates the 3.96 mm pitch and 1.57 mm board thickness constraints. Ensure compatibility with any required polarizing keys if mechanical alignment is critical for the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 18-position count suits moderate density needs. Consider the panel mount style and vertical orientation for chassis integration. Verify that the 5 A current rating meets the circuit requirements and that the operating temperature range aligns with the environmental conditions.

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 options while maintaining consistent electrical characteristics. The 305-018-520-507 specifically denotes the 18-position variant with gold plating and panel mount features, distinguishing it from other series members like the 315 or 355 lines.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different position counts. Verify mechanical fitment with alternative manufacturers' connectors offering similar 3.96 mm pitch specifications. Ensure that any substitute maintains the dual-row female contact type and compatible current ratings.
