391-057-522-107

Edgeboard Connectors Overview

The EDAC Inc. 391-057-522-107 is a standard card edge connector from the 391 series, designed for single-edge board applications. It features 57 positions with a 0.100 inch (2.54 mm) pitch and supports a board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts housed in black thermoplastic polyester. Rated for 3 A current and 5 GOhms insulation resistance, it operates within a temperature range of -40°C to +105°C. This receptacle employs panel mount installation with solder pin termination.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Thermoplastic polyester housing provides structural integrity and thermal stability.
• Panel mount design facilitates secure integration into chassis or enclosure systems.

Edgeboard Connectors Applications

• Single-edge circuit board interconnection
• Panel-mounted electronic assemblies
• Industrial control system interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 57-position configuration and 1.57 mm board thickness tolerance. Confirm that the gold contact finish meets the necessary conductivity standards for the intended application environment. Ensure the panel mount style aligns with the mechanical constraints of the assembly design before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 57-position connection is required for boards with a 1.57 mm thickness. The 3 A current rating and high insulation resistance make it suitable for general-purpose industrial electronics. Consider the vertical orientation and panel mounting requirements to ensure compatibility with the target chassis structure.

Edgeboard Connectors Part Context

This component belongs to the EDAC 391 series of standard card edge connectors. The series offers various position counts and mounting options, providing flexibility for different board sizes and mechanical layouts. The 391-057-522-107 specifically addresses the need for a mid-range position count with robust panel-mounting capabilities.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 391 series connectors with matching 57 positions and 2.54 mm pitch, such as the 391-056-522-204, provided the board thickness and mounting style are verified for interchangeability.
