• Single row female contact configuration for standard card edge mating
• Gold-plated copper alloy contacts ensure durable low-resistance connections
• Thermoplastic polyester insulator supports high-temperature operation up to +105°C
• Through-hole termination with PC pins for secure PCB integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit boards
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 345 Series Ordering Guide to confirm exact mechanical and electrical specifications. Ensure compatibility with target PCB stack-up dimensions and verify RoHS compliance status prior to procurement. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 50-position interface with 2.54 mm pitch is required. Confirm that the target application operates within the -40°C to +105°C temperature range. Validate that the PCB thickness falls within the specified 1.37 mm to 1.78 mm window to ensure proper contact engagement and mechanical stability during insertion.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 Series, a family of standard card edge connectors designed for robust industrial and commercial applications. The series offers various position counts and termination options, utilizing consistent dimensional standards for interchangeability within system designs requiring reliable high-density signal routing.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitutes. Direct replacements must match the 50-position count, 2.54 mm pitch, and single-row female configuration. Verify that alternative parts maintain identical thermal ratings and mounting styles to ensure mechanical fit.
