305-042-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-568 is a standard card edge connector designed for dual-edge board applications. It features 42 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold-plated copper alloy contacts and offers a continuous current rating of 5 A. The insulator body is green, and the unit supports solder pin termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact installation requirements
• Provides high dielectric strength with an 1800 VACrms rating

Edgeboard Connectors Applications

• Dual-edge card edge connections
• Panel-mounted electronic assemblies
• Industrial control system interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 42-position configuration and 3.96 mm pitch before ordering. Confirm that the receiving PCB design accommodates the 0.062 inch nominal thickness specification to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure compatibility with existing polarizing key requirements if used in constrained spaces.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 0.156 inch spacing is required. The 5 A current rating suits moderate power applications. The green insulator aids visual identification during assembly. Verify that the panel mount style aligns with the chassis design constraints. Consider the 1800 VACrms insulation capability for environments requiring robust electrical isolation between contacts.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors. The series is characterized by its ability to accept various polarizing keys and its standardized spacing dimensions. The 305 series provides reliable interconnection solutions for dual-edge boards, offering consistent performance across different position counts within the same family structure.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series connectors with matching 42 positions and 0.156 inch pitch. Ensure any replacement maintains the dual-edge female configuration and compatible PCB thickness tolerance.
