305-046-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-212 is a standard card edge connector from the 305 series, designed for reliable signal communication and power connection between motherboards, daughterboards, and extenders. This dual-edge female connector features 46 positions with a 0.156-inch (3.96 mm) pitch. It utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. The housing is constructed from green UL 94V-0 thermoplastic polyester, providing robust insulation and flame retardancy. Rated for 5 A continuous current and 1800 VACrms dielectric voltage, it supports between-contact and in-contact polarizing keys for secure mating alignment.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration accepts board edges from both sides for versatile mounting options
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Compatible with between-contact and in-contact polarizing keys for precise alignment
• Thermoplastic polyester insulator meets UL 94V-0 flammability standards

Edgeboard Connectors Applications

• Motherboard to daughterboard interconnections
• System extender card connections
• Industrial control panel signal routing
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm contact plating thickness and material specifications. Ensure that the selected polarizing key type matches the system design requirements for between-contact or in-contact installation. Confirm that the PCB edge card thickness falls within the connector's specified tolerance range to guarantee proper retention force and electrical contact integrity during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for high-reliability applications. The 5 A current rating makes it suitable for moderate power distribution alongside signal lines. Consider the green color coding if visual identification of connector rows is necessary. Verify compatibility with existing polarizing key systems before finalizing the design to ensure mechanical locking functionality.
