305-046-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-504 is a standard card edge connector designed for panel installation with a vertical orientation. It features 46 positions arranged in a dual configuration, utilizing a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports solder lug termination and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. It provides a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features gold-plated copper alloy contacts for corrosion resistance
• Supports dual-edge card configurations with vertical panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact count, pitch, and termination style match project requirements. Confirm RoHS compliance status and environmental ratings prior to integration. Ensure mechanical compatibility with existing panel cutouts and mating card edge specifications.

Edgeboard Connectors Selection Notes

Select this model when a high-density 46-position interface is required with a standard 3.96 mm pitch. Consider the dual-edge design for applications needing increased pin density on a single connector footprint. Verify that the target PCB or card thickness falls within the specified 1.37 mm to 1.78 mm range for proper retention.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its robust construction for industrial environments. The 305 series offers multiple position counts and termination options to suit diverse electronic assembly needs.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts or termination styles. Verify mechanical dimensions and electrical ratings before substituting with other manufacturers' equivalents to ensure interface compatibility.
