305-044-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-568 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 44 positions arranged in a dual row configuration with a 0.156-inch (3.96 mm) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports solder pin termination and accommodates board thicknesses between 0.054 inches and 0.070 inches (1.37 mm to 1.78 mm). Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features half-beam contact type for reliable signal transmission
• Includes flange characteristics for flush mounting with top opening

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Communication equipment interface modules
• Medical device internal circuit board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct flange and termination specifications. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference the 44-position count and dual-row layout with PCB design files to prevent mechanical interference during assembly.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount card edge solution is required with polarizing key compatibility. Ensure the host PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Verify that the application environment remains within the -40°C to 105°C operational limits and requires the stated current and voltage ratings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are engineered for high-reliability interconnects in demanding environments. The series offers various position counts and mounting styles, providing flexibility for diverse electronic packaging needs while maintaining consistent electrical performance standards across the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 44-position count, 0.156-inch pitch, dual-row female configuration, and vertical panel mount style. Verify identical flange dimensions and polarizing key acceptance capabilities before substitution.
