857-044-425-112

Edgeboard Connectors Overview

The EDAC Inc. 857-044-425-112 is a high-temperature card edge connector receptacle from the 857 Series. It features 44 positions with a 3.96 mm (0.156 inch) pitch and a 5.08 mm row spacing. Designed for panel mount installation at a vertical angle, it utilizes gold-plated copper alloy contacts rated for 5 A current. The housing is constructed from black polyphenylene sulfide (PPS), supporting a board thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• High-temperature resistant PPS insulator construction
• Gold-plated contact termination for reliable signal integrity
• Vertical panel mount configuration for secure integration

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• Communication equipment backplanes
• Medical device interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and insulation material specifications. Ensure the target application supports the 1.57 mm board thickness requirement. Confirm that the vertical panel mount style aligns with the mechanical design constraints of the enclosure.

Edgeboard Connectors Selection Notes

Select this component when high-temperature performance is critical, as indicated by the PPS housing material. The 44-position count and 3.96 mm pitch define the interface density. Consider the 5 A current rating for power distribution needs. Verify compatibility with single-edge card designs if applicable.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 Series, which specializes in high-temperature card edge connectors. The series offers various position counts and mounting options. The 857-044-425-112 specifically provides a 44-position configuration with gold contacts, distinguishing it from tin-plated or lower-position variants within the same family.

Edgeboard Connectors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other EDAC 857 Series parts sharing identical pitch, position count, and mounting style for potential mechanical compatibility.
