305-050-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-202 is a standard card edge connector header featuring 50 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing, designed to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts and a thermoplastic insulator body for reliable signal transmission. Rated for 5 A current at +105°C maximum operating temperature, it offers 5 GOhms insulation resistance and supports vertical panel mounting via solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-edge card edge interface with gold-plated contacts for enhanced conductivity
• Low-profile thermoplastic insulator body accommodating standard board thicknesses
• Vertical panel mount design with solder pin termination for secure installation

Edgeboard Connectors Applications

• Medical interconnect solutions including ventilators and CPAP machines
• Ambulance and medical room equipment connections
• General industrial control systems requiring robust card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and RoHS compliance details. Confirm that the selected variant matches the required 50-position dual-row layout for the intended application.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 50-position interface is required for double-sided card edge applications. The 3.96 mm pitch suits designs needing wider spacing compared to standard 2.54 mm connectors. Verify that the panel mounting style aligns with the chassis design constraints. Consider the 5 A current rating and thermal limits to ensure performance stability under operational loads without exceeding the specified temperature range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for reliable interconnection in demanding environments. The series typically features durable thermoplastic housings and corrosion-resistant contact plating. These headers are widely utilized in sectors such as medical devices, industrial automation, and telecommunications where stable electrical connections are critical for system integrity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models like 305-050-520-268 or 305-050-520-504, provided they match the 50-position count and 3.96 mm pitch. Verify that any alternative maintains the dual-row configuration and compatible board thickness tolerance. Ensure the replacement part retains the same vertical mounting orientation and solder pin termination type to fit existing PCB layouts.
