305-066-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-207 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 66 positions with a 0.156-inch (3.96 mm) pitch and supports double-row termination. The connector utilizes gold-plated copper alloy contacts with a half-beam contact type for reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, providing insulation resistance of 5 GOhms. This panel-mount header accepts PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count and termination style. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical fit. Confirm RoHS3 compliance requirements match project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for boards up to 1.78 mm thick. The 3.96 mm pitch suits applications needing fewer pins than finer pitches while maintaining robust mechanical stability. Verify that the 5 A current rating meets the electrical load requirements of the specific circuit traces being connected.

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 options for diverse electronic assembly needs. The 305 series is characterized by its durable construction and reliable performance in demanding environments, serving as a foundational interconnect solution for multiple industrial sectors.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different pin counts or termination styles. Cross-reference compatible parts within the same series to ensure identical pitch and housing dimensions. Verify that any alternative maintains the same current rating and temperature specifications.
