305-044-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-268 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features 44 positions with a 3.96 mm (0.156 inch) pitch and accommodates a nominal printed circuit board thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual row female configuration with straight orientation
• Gold-plated copper alloy contacts for reliable conductivity
• Low profile thermoplastic insulator body construction

Edgeboard Connectors Applications

• Vertical panel-mounted electronic assemblies
• Industrial control system interconnections
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position count and 3.96 mm pitch specifications. Confirm compatibility with the target PCB thickness of 1.57 mm and ensure the vertical panel mounting style aligns with the mechanical design requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface is required for panel mounting applications. Ensure the design supports the specified 5 A current rating and operates within the -40°C to +105°C environmental range. Verify that the gold contact plating meets corrosion resistance needs for the intended operational environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and 1.57 mm board thickness compatibility. The 305-044-556-268 specifically addresses applications requiring a 44-contact vertical interface solution.

Edgeboard Connectors Replacement Considerations

Cross-reference other EDAC 305 Series variants with identical 44 positions and 3.96 mm pitch. Verify that alternative parts maintain the same vertical panel mounting style, gold contact plating, and thermoplastic insulator material properties.
