345-066-542-402

Edgeboard Connectors Overview

The EDAC Inc. 345-066-542-402 is a standard card edge connector from the 345 series, designed for vertical through-hole mounting. It features a single female contact configuration with 66 positions and a 0.100-inch (2.54mm) pitch. The contacts are gold-plated copper alloy cantilever springs, rated for 3A current. The housing is green thermoplastic polyester, supporting board thicknesses of 0.054 to 0.070 inches (1.37 to 1.78mm). Operating temperature ranges from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Single-edge female contact design with cantilever spring terminals for reliable signal transmission
• Gold-plated copper alloy contacts ensure durability and low contact resistance
• Thermoplastic polyester housing provides thermal stability and high insulation resistance
• Vertical through-hole termination facilitates secure PCB integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing reliable signal pathways
• Telecommunications infrastructure components
• Automotive electronics applications

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB trace widths and board thickness tolerances before procurement. Cross-reference RoHS compliance status with the latest manufacturer datasheets to meet regulatory requirements for your region.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 66-position interface is required for vertical board-to-board connections. Consider the 0.100-inch pitch constraint and the need for gold-plated contacts in environments where corrosion resistance is critical. Evaluate the thermal rating range against operational extremes to ensure long-term reliability under heat stress.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and configurations to support diverse connectivity needs. The 345-066-542-402 specifically addresses applications requiring a high-density single-edge interface with standardized mechanical dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffix variations for minor mechanical or material differences. Verify that any replacement maintains the same 66-position count, single-edge orientation, and vertical mounting style to ensure physical and electrical compatibility.
