305-044-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-044-500-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A continuous current and 1800 VACrms, it supports panel mounting in a vertical orientation. The unit accepts between-contact and in-contact polarizing keys to ensure secure mating.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Accepts between-contact and in-contact polarizing keys
• Thermoplastic polyester housing with green coloration

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge connection
• Industrial control systems utilizing polarized card interfaces
• High-voltage circuit interconnections up to 1800 VACrms
• Vertical board-to-board or backplane integration

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness, housing material variants, and mounting hardware compatibility. Ensure that the polarizing key requirements match the system design specifications before procurement. Cross-reference the part number with the latest EDAC documentation to confirm current manufacturing status and RoHS compliance details.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge configuration with a 3.96 mm pitch is required for vertical panel mounting. The 44-position count and 5 A rating suit moderate-density applications. Consider the acceptance of polarizing keys if mechanical alignment is critical. Verify that the operating temperature range of -40°C to +105°C meets the environmental constraints of the target installation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing a consistent 3.96 mm pitch. The 305-044-500-503 variant specifically addresses dual-edge applications with gold contacts. It is distinct from single-edge or different pitch variants within the broader EDAC connector portfolio.
