845-106-556-204

Edgeboard Connectors Overview

The EDAC Inc. 845-106-556-204 is a standard card edge connector from the 845 Series, designed for high-temperature environments. It features a dual-edge configuration with 106 positions and a 0.100 inch (2.54 mm) pitch. The contacts are gold-plated copper alloy cantilever type, housed in a green diallyl phthalate (DAP) casing. This panel-mount vertical connector supports female termination for reliable signal transmission in demanding applications.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates double-sided circuit boards for increased I/O density
• Gold-plated cantilever contacts ensure low contact resistance and durable mating cycles
• High-temperature rated construction suitable for harsh operational conditions

Edgeboard Connectors Applications

• Industrial control systems requiring robust connectivity
• Telecommunications equipment infrastructure
• Automotive electronic modules
• Medical device instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish thickness and housing color variations. Ensure compatibility with the target PCB edge guide dimensions and panel cutout specifications. Confirm that the dual-edge orientation aligns with the system mechanical constraints before procurement.

Edgeboard Connectors Selection Notes

Select this model when dual-sided board integration is required within the 845 series family. The 106-position count suits moderate-density applications. Verify that the 0.100-inch pitch matches the existing board layout. Consider the high-temperature rating if the operating environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 Series of high-temperature card edge connectors. The series offers various position counts and mounting styles. The 845-106-556-204 specifically denotes the 106-position variant with dual-edge female contacts and green DAP housing, distinct from single-edge or different pitch alternatives.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 845-106-556-207. Verify pin count and pitch compatibility. Cross-reference mechanical drawings for panel mount hole patterns. Ensure equivalent electrical ratings for temperature and current capacity.
