745-038-520-201

Edgeboard Connectors Overview

The EDAC Inc. model 745-038-520-201 is a dual-edge female card edge connector from the 745 Series Ultra-Mate. It features 38 positions with a 0.100-inch (2.54 mm) pitch and press-fit termination for through-hole mounting. The contacts are gold-plated copper alloy with a thickness of 30.0 µin (0.76 µm). Designed for non-specified dual-edge cards, it supports board thicknesses of 0.054 to 0.070 inches (1.37 to 1.78 mm) and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration provides electrical connectivity along both sides of the card edge.
• Press-fit termination ensures secure mechanical attachment and reliable electrical contact on the printed circuit board.
• Gold-plated contacts offer corrosion resistance and stable signal transmission in demanding environments.

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the target application requires a dual-edge connector rather than single-edge variants within the same series. Confirm that the host PCB layout accommodates the specific press-fit pin geometry and spacing defined by the manufacturer's dimensional drawings. Ensure compatibility with the specified card thickness range to maintain proper retention force and electrical engagement during assembly.

Edgeboard Connectors Selection Notes

Select this component when dual-sided contact is necessary for higher density or redundancy compared to single-edge alternatives. The press-fit installation method eliminates the need for soldering, which may be preferred for high-temperature processing or reworkability requirements. Consider the 745 series packaging options if bulk handling efficiency is a priority for production lines.

Edgeboard Connectors Part Context

This part belongs to the EDAC 745 Series Ultra-Mate family, designed for high-reliability applications. The series offers various position counts and termination styles, including press-fit and wire wrap options. The 745-038-520-201 specifically addresses needs for dual-edge connectivity with standardized 2.54 mm pitch dimensions common in legacy and industrial interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 745 series dual-edge connectors with matching 38-position counts and press-fit terminations, such as the 745-038-540-201. Verify that any replacement maintains identical pitch, card thickness tolerance, and contact material specifications to ensure mechanical and electrical interchangeability without redesigning the host PCB.
