305-018-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-268 is a standard card edge connector designed for panel mount applications. It features an 18-position, dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A current at temperatures ranging from -40°C to +105°C, it employs a solder lug termination type and a thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided PCBs
• Low-profile insulator body constructed from thermoplastic material
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount installation style provides secure mechanical fixation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific termination style against project requirements, as this model specifies solder lug connections rather than standard pins. Confirm that the target printed circuit board thickness aligns with the 1.57 mm nominal specification to ensure proper seating within the connector housing. Cross-reference the manufacturer datasheet for precise dimensional tolerances and mating force characteristics before finalizing the bill of materials.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for double-sided cards. The 3.96 mm pitch offers robust spacing for higher current applications compared to finer pitches. Ensure the enclosure design allows for the necessary panel cutout dimensions compatible with the 305 series form factor. Consider the operating temperature range if the environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, catering to various industrial and commercial electronic assemblies. The 305 series maintains consistent electrical performance across different configurations, providing a standardized solution for modular hardware designs requiring durable edge connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-018-520-568 and 305-018-555-208. Verify compatibility regarding termination type, as some variants use solder pins instead of lugs. Ensure any replacement maintains the 18-position count and 3.96 mm pitch to fit existing panel cutouts and PCB layouts without modification.
