746-054-541-506

Edgeboard Connectors Overview

The EDAC Inc. 746-054-541-506 is a single-row female card edge connector designed for vertical through-hole mounting. It features 54 positions with a 0.125-inch (3.18mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The contacts are made of copper alloy with a gold finish, utilizing a cantilever spring design for reliable engagement. This component belongs to the 746 Series and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Cantilever contact design ensures secure connection with standard card edge boards
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance
• Vertical through-hole termination supports stable PCB integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 746 Series Ordering Guide to ensure compatibility with required termination styles and plating specifications. Confirm that the intended application board thickness falls within the specified 0.054 to 0.070 inch range to guarantee proper mechanical fit and electrical performance.

Edgeboard Connectors Selection Notes

Select this model when a single-row configuration with a 0.125-inch pitch is required for high-reliability applications. The cantilever contact type offers ease of insertion compared to other terminal designs. Ensure the operating environment remains within the -40°C to 105°C thermal limits defined by the thermoplastic polyester insulation material.

Edgeboard Connectors Part Context

This component is part of the EDAC 746 Series Ultra-Mate line, which specializes in press-fit and standard card edge connectors. The series provides various position counts and row configurations to support diverse electronic assembly needs. The 746-054-541-506 specifically addresses requirements for medium-density single-row connections in rugged environments.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 746 Series cross-reference documentation for verified substitute part numbers. Direct replacements must maintain identical pitch, row count, and termination style to ensure mechanical interchangeability without redesigning the host PCB footprint.
