345-138-541-278

Edgeboard Connectors Overview

The EDAC Inc. 345-138-541-278 is a standard card edge connector featuring 138 positions with a 0.100 inch (2.54 mm) pitch. It utilizes a dual-edge configuration for female contacts, which are gold-plated to ensure reliable signal transmission. The housing is constructed from green thermoplastic polyester, providing durability and insulation. Designed for panel mount installation at a right angle, this component supports a PCB thickness range of 0.054 to 0.070 inches. It employs a solder pin termination type for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates non-specified card types for versatile interface compatibility
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Right-angle panel mount style facilitates structured equipment integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications infrastructure hardware
• Medical device internal circuitry connections

Edgeboard Connectors Procurement Notes

Verify the specific contact finish and material composition against the official manufacturer datasheet before procurement. Confirm that the target printed circuit board thickness falls within the specified 0.054 to 0.070 inch range to ensure proper mechanical engagement. Check RoHS compliance status directly with the supplier or manufacturer documentation to meet regulatory requirements for your specific region and application standards.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 138 positions is required in a limited panel space. The dual-edge architecture allows for increased pin count compared to single-edge alternatives without increasing the footprint. Ensure the mating card edge thickness aligns with the connector's tolerance. Consider the right-angle orientation for cable management and spatial constraints within the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, a line of standard card edge connectors designed for general-purpose electronic applications. The series offers various position counts and mounting styles to suit different board densities. As a panel-mount solution, it differs from board-to-board connectors by providing a fixed interface point for removable cards or backplanes in larger assemblies.
