305-044-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-203 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 44 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The connector utilizes gold-plated contacts on a copper alloy base, housed within a green thermoplastic polyester insulator. It supports printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The unit operates reliably within a temperature range of -40°C to 105°C and includes flange features for secure installation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced board alignment
• Provides a continuous current rating of 5A and withstands 1800VACrms dielectric strength
• Features a low-profile insulator body constructed from thermoplastic polyester

Edgeboard Connectors Applications

• Industrial control systems requiring robust signal transmission
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct pin count, plating thickness, and insulation color specifications. Confirm that the target application PCB thickness falls within the accepted range of 0.054 to 0.070 inches to guarantee proper mechanical engagement. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure that the required polarizing key configuration matches the available options documented in the series guide.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 44 contacts is required for vertical panel mounting. The 0.156-inch pitch accommodates standard board layouts while maintaining adequate spacing for high-voltage isolation up to 1800VACrms. Consider the gold plating for corrosion resistance in demanding environments. Evaluate the thermal performance limits of -40°C to 105°C against operational conditions. Compare physical dimensions against enclosure constraints due to the flange diameter and overall height.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors designed for general-purpose electronic interconnects. The series offers various position counts and row configurations to support diverse board architectures. Components in this family typically feature durable metal alloys and stable polymer insulators suitable for repeated mating cycles or fixed installations in industrial settings.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing pin counts or row arrangements. Verify compatibility with existing polarizing key requirements when selecting alternative parts from the same series.
