857-028-458-108

Edgeboard Connectors Overview

The EDAC Inc. 857-028-458-108 is a standard card edge connector receptacle designed for high-temperature applications. It features 28 positions with a single row configuration and a pitch of 3.96 mm (0.156 inches). The housing is constructed from black polyphenylene sulfide, supporting a board thickness of 1.57 mm. Contact plating utilizes tin finish on copper alloy terminals, rated for 5 A current. The component employs wire wrap termination and is intended for vertical panel mount installation.

Edgeboard Connectors Feature Summary

• High-temperature resistant polyphenylene sulfide housing construction
• Single row female contact configuration with tin-plated copper alloy terminals
• Vertical panel mount design with wire wrap termination method

Edgeboard Connectors Applications

• Industrial control systems requiring high thermal stability
• Communication equipment interfaces
• Medical device circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal plating type, as variations exist within the series. Confirm that the target application supports wire wrap termination processes rather than surface mount or through-hole soldering. Ensure the PCB design accommodates the specified 1.57 mm board thickness and 3.96 mm pitch constraints for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a single-row card edge interface is required with vertical orientation. The tin-plated contacts offer cost-effective conductivity suitable for general industrial environments. Verify that the operating temperature range aligns with the material specifications of the polyphenylene sulfide housing for reliable performance under thermal stress.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of high-temperature card edge connectors. The series provides various position counts while maintaining consistent 3.96 mm pitch dimensions. The 857 series is engineered for durability in demanding electronic assemblies where standard connectors may fail due to thermal or mechanical stress.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other EDAC 857 series variants only if pin count and termination method requirements can be adjusted accordingly.
