346-044-526-258

Edgeboard Connectors Overview

The EDAC Inc. 346-044-526-258 is a standard card edge connector receptacle from the 346 series. It features 44 positions with a 3.175 mm (0.125 inch) pitch, designed for dual-edge card insertion. The connector supports a maximum board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 3 A current, it employs a thermoplastic polyester insulator in green. The unit is configured for panel mounting at a vertical angle, providing secure mechanical retention for high-density interconnect applications.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and plating specifications. Ensure compatibility with target PCB stack-up dimensions and mating card thickness limits before procurement. Cross-reference RoHS compliance status with current manufacturer declarations to meet regulatory requirements for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-edge interface is required within the 346 series family. Confirm that the 3.175 mm pitch aligns with the design rules of the mating card edge. Evaluate the vertical panel mount form factor against spatial constraints and thermal management needs of the enclosure design prior to finalizing the bill of materials.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent dimensional standards. The 346 series is engineered for general-purpose industrial and commercial applications requiring durable and reliable electrical connections between printed circuit boards and chassis-mounted receptacles.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 346 series variants with matching 44 positions and 3.175 mm pitch. Verify mechanical footprint and pinout alignment when considering alternative manufacturers. No cross-brand direct replacements are confirmed without detailed engineering validation.
