305-084-556-508

Edgeboard Connectors Overview

The EDAC 305-084-556-508 is a standard card edge connector header from the 305 series. It features an 84-position dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. Designed for panel mounting at a vertical angle, it utilizes solder pin termination. The contacts are gold-plated copper alloy, rated for 5 A continuous current. The insulator body accommodates a nominal PCB thickness of 1.57 mm (0.062 inch).

Edgeboard Connectors Feature Summary

• Dual-row female connector design accepting .062 inch nominal thickness printed circuit boards.
• Accepts between-contact and in-contact polarizing keys for secure board alignment.
• Low profile insulator body constructed from thermoplastic material.

Edgeboard Connectors Applications

• High-density electronic module interconnection
• Panel-mounted system integration
• Industrial control hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer datasheet to confirm RoHS compliance status and exact insulation resistance values. Ensure the selected variant matches the required termination style and mounting orientation for the target assembly. Cross-reference official part numbers to avoid confusion with similar pitch or position configurations within the product family.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface with a 3.96 mm pitch is required. The dual-row layout supports significant signal density in a compact footprint. Verify that the mating card edge thickness aligns with the 1.57 mm specification to ensure proper mechanical engagement and electrical contact reliability.
