305-046-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-204 is a standard card edge connector featuring 46 positions with a 3.96 mm (0.156 inch) contact spacing. It utilizes a dual female configuration designed for vertical panel mounting. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and a voltage rating of 1800 VACrms. Contacts are gold-plated copper alloy, terminated via solder lugs.

Edgeboard Connectors Feature Summary

• Dual edge female design for secure PCB connection
• Vertical panel mount installation style
• Gold-plated contacts for reliable conductivity
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing keys and board thickness. Confirm that the 46-position count matches the target PCB layout. Check RoHS compliance status if environmental regulations apply to the assembly. Ensure the solder lug termination method aligns with the manufacturing process capabilities.

Edgeboard Connectors Selection Notes

Select this component when a high-voltage, dual-edge interface is required for thick PCBs. The 3.96 mm pitch suits applications needing robust mechanical retention. Consider the 5A current rating for power distribution needs. Verify that the vertical orientation fits within the enclosure constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors. The series offers various position counts and contact spacings. The 305 series is characterized by low-profile insulator bodies and durable construction suitable for repeated mating cycles in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different position counts. Verify that substitute models maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance to ensure mechanical fit.
