305-044-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-507 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 44 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. It supports solder pin termination and accommodates board thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A continuous current and 1800 VACrms insulation, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure connection to non-specified card edge boards
• Accepts both between-contact and in-contact polarizing keys for enhanced alignment
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic housing provides structural integrity and electrical insulation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density interconnects
• Industrial control systems utilizing dual-edge card edge modules
• Test and measurement equipment interfaces
• Communication hardware backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compatibility with required polarizing keys and mounting hardware. Ensure that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with authorized distributors to validate current availability and lead times.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for dual-edge cards with a 3.96 mm pitch. The 44-position configuration suits applications needing moderate I/O density. Consider the 5 A current rating and 1800 VACrms insulation voltage for power and signal integrity requirements. The gold finish is suitable for environments where oxidation resistance is critical. Verify that the M3 threaded insert feature aligns with the chassis mounting design.
