857-018-440-202

Edgeboard Connectors Overview

The EDAC Inc. 857-018-440-202 is a standard card edge connector featuring 18 positions with a 3.96 mm pitch. It utilizes a dual-edge female contact configuration and tin plating for termination. Designed for panel mount installation in a vertical orientation, the housing is constructed from black thermoplastic material. The component supports a PCB thickness range of 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card types
• Vertical panel mount style ensures secure structural integration
• Tin-plated contacts provide reliable electrical connectivity
• High-temperature resistant housing material supports extended operational ranges

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics module interfaces
• Medical device circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact contact finish and housing material variations. Ensure the target application PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Confirm that the vertical panel mount orientation aligns with the system enclosure design requirements before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a 18-position connection is required with a 3.96 mm pitch. The dual-edge configuration is suitable for cards requiring contact on both edges. Consider the vertical mounting style for space-constrained panel installations. Verify that the operating environment temperature does not exceed the maximum rating of +125°C to maintain insulation resistance and material integrity over the product lifecycle.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of card edge connectors. The series offers various position counts and termination options. The 857-018-440-202 variant specifically provides 18 positions with tin plating. This series is designed for general-purpose applications requiring robust mechanical retention and reliable signal transmission in industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 857 series variants with matching 18 positions and 3.96 mm pitch. Verify compatibility regarding contact plating type and housing material composition. Ensure replacement parts maintain the same vertical panel mount orientation and dual-edge contact configuration to preserve mechanical fit and electrical performance.
