305-026-521-503

Edgeboard Connectors Overview

The EDAC 305-026-521-503 is a standard card edge connector featuring 26 positions with a 3.96 mm pitch. Designed for panel mount installation, it utilizes a vertical orientation and solder pin termination. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. It supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The housing is made of thermoplastic polyester, suitable for robust industrial applications requiring secure board-to-panel connections.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for precise alignment
• Provides high dielectric strength with 1800 VACrms insulation capability
• Features gold-plated copper alloy contacts for durable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge interfaces
• Panel-mounted electronic modules needing secure vertical connection
• High-voltage signal transmission environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish thickness and housing color variations. Ensure compatibility with the target PCB edge thickness and verify that the required polarizing keys match the connector's acceptance specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 26-position interface with a 3.96 mm pitch is required. It is appropriate for designs necessitating panel mounting and vertical termination. Consider the 5 A current rating and 1800 VACrms insulation limits to ensure electrical safety margins are met for the intended application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to accept polarizing keys and its robust construction for industrial use. Similar parts in the series vary primarily by position count and specific housing configurations while maintaining consistent pitch and termination methods.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-026-521-107 and 305-026-521-503 variants with different housing colors or minor material updates. Verify that any replacement maintains the 3.96 mm pitch and 26-position count to ensure mechanical fit.
