305-050-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-050-500-508 is a standard dual-row card edge connector designed for panel mounting applications. It features 50 positions with a 3.96 mm (0.156 inch) pitch and accepts board thicknesses between 1.37 mm and 1.78 mm. The contacts are made of copper alloy with gold plating, rated for 5 A current at +105°C maximum operating temperature. Insulation resistance is specified at 5 GOhms, and the housing utilizes thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 50 contact positions
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount vertical installation style
• Thermoplastic insulation housing

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact type and plating thickness. Ensure the target PCB design accommodates the required 3.96 mm pitch and 1.37–1.78 mm board thickness range. Confirm that the panel mounting hole specifications align with the connector's flange dimensions before finalizing the bill of materials.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, vertically mounted card edge solution is required for high-reliability industrial environments. The 3.96 mm pitch offers spacing suitable for higher voltage isolation compared to finer pitches. Verify compatibility with existing mating edge cards and ensure the thermal rating meets the operational environment requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting options and position counts for card edge applications. The series is characterized by its durable construction and standardized dimensions, facilitating integration into modular electronic systems where secure mechanical and electrical connections are critical.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers or mounting variations. Cross-reference the mechanical drawing for exact footprint compatibility when evaluating alternative manufacturers' offerings.
