305-052-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-203 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 52 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) pitch. The connector accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm. Constructed with copper alloy contacts and a thermoplastic polyester insulator, it offers gold plating on the terminals. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a floating lineal flange design with a 2.95 mm diameter for flush installation
• Utilizes half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment with high-density connection needs
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct pin count, pitch, and termination style. Confirm that the required PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Check RoHS compliance status if restricted substances are a concern for your assembly process. Ensure panel mounting holes align with the connector's flange specifications before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 52-position interface with a 3.96 mm pitch is required. It is suitable for applications needing a 5 A current rating and operation up to 105°C. Consider the vertical panel mount style and solder pin termination for integration into chassis-based designs. Verify compatibility with polarizing keys if additional board stability is necessary for the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and configurations for diverse electronic interconnect needs. The 305-052 variant specifically addresses requirements for higher density connections while maintaining the mechanical robustness characteristic of the series. It serves as a reliable interface solution for edge-board applications in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-050-520-203 and 305-052-520-207, provided the position count and electrical ratings match the design requirements. Verify that any alternative part maintains the same 3.96 mm pitch and dual female configuration to ensure mechanical fit and electrical continuity without redesigning the PCB or panel.
