746-040-525-101

Edgeboard Connectors Overview

The EDAC Inc. 746-040-525-101 is a standard card edge connector from the 746 series, designed for single-edge board applications. It features a female contact configuration with 40 positions and a 0.125-inch (3.18mm) pitch. The connector utilizes press-fit termination methods and gold-plated contacts to ensure reliable signal transmission. Constructed with a copper alloy contact material and a black thermoplastic polyester insulator, it supports through-hole mounting. The unit is rated for operation within a temperature range of -40°C to 105°C and accommodates card thicknesses between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Gold-plated contacts on copper alloy for corrosion resistance
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronic circuit boards
• Medical device internal connections
• Energy management hardware modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 746 Series Ordering Guide to confirm exact physical dimensions and plating specifications. Ensure compatibility with the target PCB layout regarding press-fit hole requirements and overall connector height. Cross-reference the RoHS3 compliance status if environmental regulations apply to the final assembly. Confirm that the single-edge configuration matches the mechanical constraints of the host enclosure.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface is required for high-density signal routing. The 0.125-inch pitch offers a balance between pin count and spacing for standard logic signals. Consider the press-fit termination for applications requiring robust mechanical retention without soldering thermal stress. Evaluate the operating temperature range against the environmental conditions of the deployment site to ensure long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 746 series, which provides a broad range of standard card edge connectors. The series includes various configurations for single and dual-edge applications with different pin counts and termination styles. The 746 series is widely used in industries requiring reliable interconnect solutions for printed circuit boards, offering consistent performance across diverse electronic systems.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 746 Series Ordering Guide for direct substitutes with identical electrical and mechanical parameters. Verify that any alternative maintains the same 0.125-inch pitch and single-edge female configuration. Ensure that replacement parts match the press-fit termination style and compatible card thickness specifications.
