305-042-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-568 is a standard card edge connector from the 305 series, designed for panel mount installation with vertical orientation. It features 42 positions in a dual configuration with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy and gold plated to ensure reliable signal transmission. This component supports solder pin termination and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. It operates within a temperature range of -40°C to +105°C and carries a 5 A current rating.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual female contact configuration for robust board-to-board connectivity
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment with standardized card edge interfaces
• Test and measurement devices needing precise signal routing

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to ensure correct polarity keying and contact plating specifications. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure panel mounting holes align with the connector's flange dimensions for secure installation.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 42-position interface with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms insulation capability for electrical safety margins. Choose this variant over single-row options if higher density connections are needed on both sides of the card. Verify compatibility with existing polarizing key requirements before finalizing the design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are widely used in industrial and commercial applications. The series offers various position counts and configurations to suit different design needs. The 305 series is known for its durability and consistent performance in demanding environments, making it a preferred choice for engineers designing reliable electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with identical pitch and position count but different flange or keying options. Cross-reference with manufacturer ordering guides to confirm mechanical and electrical equivalence. Ensure any replacement maintains the same current rating and voltage insulation standards.
