305-044-521-508

Edgeboard Connectors Overview

The EDAC 305-044-521-508 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features 44 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, supporting a continuous current rating of 5 A and 1800 VACrms insulation. The housing is green thermoplastic, accommodating board thicknesses between 1.37 mm and 1.78 mm. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-edge female contact design for non-specified card edge boards
• Solder termination type ensures reliable mechanical and electrical connection

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing dual-edge card insertion
• Test and measurement devices needing high-reliability signal paths

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with existing panel cutouts and PCB stack-up requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-row interface is required with a 3.96 mm pitch. Confirm that the target PCB thickness falls within the 1.37 mm to 1.78 mm range. Verify that the application environment supports the specified operating temperature range and voltage ratings. Ensure polarizing key compatibility if mechanical alignment is critical.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized card edge solutions. The series is characterized by consistent 3.96 mm spacing and robust construction suitable for various industrial applications. The 305-044 variant specifically addresses higher density needs within the same form factor constraints as other series members.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include variants with different position counts or termination styles, such as the 305-044-521-202. Verify that any replacement maintains identical pitch, row count, and mounting configuration to ensure mechanical fit.
