392-090-556-212

Edgeboard Connectors Overview

The EDAC Inc. 392-090-556-212 is a high-reliability card edge connector from the 392 series, designed for dual-edge board applications. It features 90 positions arranged in two rows with a 0.100 inch (2.54mm) pitch. The connector utilizes female contacts made of copper alloy with gold plating and employs surface mount terminals for PCB attachment. The insulator is black thermoplastic polyester, rated for operation between -40°C and +105°C. It accommodates card thicknesses from 0.054 to 0.070 inches.

Edgeboard Connectors Feature Summary

• Dual-edge configuration supports connection to both sides of the circuit board simultaneously.
• Surface mount terminal style ensures secure attachment to the printed circuit board.
• Gold-plated copper alloy contacts provide reliable electrical conductivity and corrosion resistance.
• Flanged design with side openings facilitates flush mounting without threading requirements.

Edgeboard Connectors Applications

• High-reliability industrial control systems
• Military and aerospace electronic assemblies
• Telecommunications infrastructure equipment

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required dual-edge configuration and surface mount termination style. Confirm that the supplier provides original manufacturer documentation to ensure authenticity. Check compatibility with the target PCB layout regarding hole diameter and mounting flange specifications before finalizing orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for robust signal integrity in harsh environments. Ensure the PCB design supports surface mount technology rather than through-hole methods. Verify that the board thickness falls within the specified range of 0.054 to 0.070 inches for proper mechanical engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 392 series, which specializes in high-reliability interconnect solutions. The series is widely recognized for use in demanding sectors such as defense and aerospace where consistent performance under stress is critical. The model number indicates specific pin count and series characteristics within the broader product family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 392 series connectors with matching 90-position dual-edge configurations. Ensure any replacement maintains the same 0.100 inch pitch and surface mount terminal type. Verify that alternative parts meet identical environmental ratings and material specifications for direct interchangeability.
