857-044-527-104

Edgeboard Connectors Overview

The EDAC Inc. part number 857-044-527-104 is a single-row card edge connector from the 857 series, designed for high-reliability applications. It features 44 positions with a 0.156-inch (3.96 mm) contact pitch. The connector utilizes gold-plated copper alloy contacts and a black thermoplastic housing. It is specified as a female receptacle intended for vertical panel mount installation. The component supports a PCB thickness range of 0.054 to 0.070 inches and operates within a temperature range of -40°C to +125°C.

Edgeboard Connectors Feature Summary

• Single-edge female receptacle configuration for secure board insertion
• Gold-plated contacts ensure reliable signal transmission in demanding environments
• Flush mount flange design facilitates stable panel integration
• High-temperature rated construction suitable for industrial and aerospace use

Edgeboard Connectors Applications

• Aerospace avionics systems requiring high reliability

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm plating thickness and material specifications. Confirm availability status as lead times may vary due to supply chain constraints. Ensure compatibility with existing panel cutouts and PCB thickness tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-pitch connection is required for robust mechanical stability. The 0.156-inch pitch accommodates thicker circuit boards compared to standard 0.100-inch options. Consider the flush mount feature for applications where space efficiency and panel alignment are critical design factors.

Edgeboard Connectors Part Context

This connector belongs to EDAC's specialized line of rugged interconnect solutions, often utilized in sectors where vibration resistance and environmental sealing are paramount. The 857 series distinguishes itself through its specific flange geometry and high-temperature polymer composition, catering to niche industrial and defense markets.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 44-position count, 0.156-inch pitch, and single-row female configuration. Verify that alternative components support the same PCB thickness range and maintain equivalent thermal ratings for seamless integration without redesigning the host panel or enclosure.
