305-040-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-508 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 40 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and includes solder lug termination for secure board attachment. It accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and provides a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Designed for non-specified dual-edge card types with female contact interfaces

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge architectures
• Test and measurement devices needing high-density signal routing

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required row spacing and termination style. Confirm compliance with RoHS directives and REACH regulations before integration. Ensure the selected variant aligns with the designated polarizing key requirements for the target assembly.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch is required for dual-edge card connections. Consider the 5 A current rating and 1800 VACrms insulation capability for electrical safety margins. Evaluate the vertical panel mount style against available chassis space constraints.

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 while maintaining consistent mechanical dimensions. It serves as a reliable interface solution for modular electronic systems requiring durable physical connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical 40-position layouts. Verify compatibility with existing polarizing key configurations and panel cutout dimensions before substitution.
