345-026-521-202

Edgeboard Connectors Overview

The EDAC Inc. 345-026-521-202 is a standard card edge connector from the 345 series, designed for reliable signal transmission in electronic assemblies. It features a 26-position configuration with a 0.100 inch (2.54mm) pitch and supports dual-edge card insertion. The connector utilizes gold-plated copper alloy contacts to ensure low resistance and corrosion resistance. It is rated for 3A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing robust insulation and mechanical stability.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided circuit boards for increased I/O density.
• Gold-plated bellowed-type contacts provide durable connection with low contact resistance.
• Thermoplastic polyester insulator offers high dielectric strength and thermal stability.
• Vertical mounting style facilitates direct panel or board integration.

Edgeboard Connectors Applications

• Industrial control systems requiring modular interface connections
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronics subsystems

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, contact finish, and termination type. Ensure compatibility with the target PCB stack-up and card thickness specifications before procurement. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with 26 positions and 2.54mm pitch is required. Consider the 3A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the vertical mounting orientation and through-hole termination method align with the assembly design constraints.

Edgeboard Connectors Part Context

This connector belongs to EDAC's 345 series, which provides a range of standard card edge solutions. The series is characterized by consistent dimensional tolerances and material properties across various position counts. It serves as a standardized interconnect solution for replacing legacy connectors or designing new modular electronic hardware.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 345-026-521-802 and 341-026-521-202. Verify that alternative parts match the 26-position count, 0.100 inch pitch, and dual-edge configuration. Confirm that termination types and mounting styles are identical to ensure mechanical fit without redesign.
