305-046-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-558 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 46 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is constructed from thermoplastic material. Electrical specifications include an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C. Termination is achieved via solder eyelets.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card types with semi-bellows contact geometry.
• Low-profile thermoplastic insulator body provides structural integrity for panel-mounted installations.
• Gold-plated copper alloy contacts ensure reliable signal transmission within specified thermal limits.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standard thickness PCBs
• Medical devices needing high insulation resistance connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with 1.57 mm board thickness before integration. Cross-reference RoHS compliance status directly with the manufacturer's latest datasheet revision. Confirm that the 5 A rating aligns with your system's electrical load requirements under maximum operating temperatures.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution is required for dual-edge cards. The 3.96 mm pitch suits applications needing wider spacing between signal lines. Consider the 5 A current rating for power distribution or high-current signal paths. Verify that the -40°C to +105°C range meets environmental conditions. The solder eyelet termination requires compatible PCB pad designs for secure assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305 series is characterized by its use of thermoplastic insulators and gold-plated contacts. It serves as a foundational component for modular electronic assemblies where reliable panel mounting is essential. Other parts in the series share similar mechanical dimensions but differ in contact quantity.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 46-position count, 3.96 mm pitch, and dual-row configuration. Verify that alternative components support the same 1.57 mm board thickness and solder eyelet termination. Ensure equivalent current ratings and temperature ranges are maintained. Check for identical panel mount orientation and flange features to guarantee mechanical fit without redesigning the enclosure.
