887-020-523-807

Edgeboard Connectors Overview

The EDAC 887-020-523-807 is a standard high-temperature card edge connector receptacle from the 887 series. It features 20 positions in a dual-row configuration with a 3.96 mm (0.156 inch) contact spacing. Designed for double-sided daughter boards, it accommodates a board thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, and the housing is constructed from polyphenylene sulfide (PPS), rated UL 94V-0. This component supports panel mount installation and offers versatile termination options.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for reliable connection to double-sided daughter boards
• High-temperature polyphenylene sulfide insulator ensures stability in demanding thermal environments
• Gold-plated copper alloy contacts provide low contact impedance and corrosion resistance
• Versatile mounting and termination configurations including offset ears and various tail styles

Edgeboard Connectors Applications

• High-temperature industrial control systems requiring robust interconnects
• Double-sided printed circuit board assemblies needing secure edge connections
• Panel-mounted electronic modules utilizing standard card edge interfaces
• Aerospace or military applications where PPS material reliability is required

Edgeboard Connectors Procurement Notes

Verify the specific termination style and mounting ear configuration against the full datasheet, as the base model number may correspond to multiple physical variants. Confirm that the dual-row, 20-position specification matches the target PCB layout. Ensure the operating environment remains within the -40°C to +125°C range for optimal performance of the PPS housing.

Edgeboard Connectors Selection Notes

Select this part when a dual-row, 20-position interface is required for double-sided cards. The 3.96 mm pitch suits standard board designs. Choose this over single-row variants if higher density per width is needed. Verify that the panel mount option aligns with the enclosure design. Consider the PPS material for superior heat resistance compared to DAP alternatives.

Edgeboard Connectors Part Context

This component belongs to the EDAC 887 series, which specializes in high-temperature card edge connectors. The series utilizes polyphenylene sulfide (PPS) insulation, distinguishing it from the 837 series which uses diallyl phthalate (DAP). The 887 series is engineered for applications exceeding standard temperature limits, offering enhanced durability and electrical performance in harsh conditions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 887 series parts with identical position counts and row configurations but different termination styles. Cross-series replacement with the 837 series is possible only if lower temperature ratings are acceptable, noting the material difference between PPS and DAP.
