396-040-526-258

Edgeboard Connectors Overview

The EDAC Inc. model 396-040-526-258 is a standard card edge connector designed for dual-edge mating configurations. It features 40 female contact positions with a 0.125-inch (3.18mm) pitch. The contacts are gold-plated over nickel to ensure reliable signal transmission and corrosion resistance. The housing is constructed from black thermoplastic polyester, providing mechanical stability and insulation. This vertical mount connector supports printed circuit boards up to 1.57mm in thickness, facilitating secure board-to-board or backplane connections.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for robust board interface
• Gold plating on contact surfaces for enhanced conductivity
• Vertical mounting orientation for space-efficient assembly
• Black thermoplastic polyester insulator for durability

Edgeboard Connectors Applications

• Backplane interconnects in industrial control systems
• High-density data processing modules
• Telecommunications equipment interfaces
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation before procurement. Confirm that the gold plating specification matches the application requirements. Ensure the PCB thickness tolerance aligns with the connector's design limits. Cross-reference the part number suffixes to confirm exact pin count and edge type compatibility.

Edgeboard Connectors Selection Notes

Select this component when a high-reliability dual-edge connection is required for thick PCBs. The 0.125-inch pitch offers a balance between density and manufacturability. Consider the vertical form factor for constrained enclosures. Validate that the gold contact finish meets the environmental exposure standards of the target deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the EDAC 396 series of standard card edge connectors. The series provides various position counts and edge configurations. The 396-040-526-258 specifically addresses the need for 40-position dual-edge connectivity. It complements single-edge variants within the same product family for diverse system architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 396 series parts with identical 40-position dual-edge specifications. Verify pitch and plating equivalence when considering cross-manufacturer alternatives. Ensure mechanical dimensions match the existing footprint constraints.
