887-021-542-112

Edgeboard Connectors Overview

The EDAC Inc. 887-021-542-112 is a high-temperature card edge connector from the 887 series, designed for single-row applications with 21 positions. It features female contacts with a 0.156-inch (3.96mm) pitch and 0.200-inch (5.08mm) row spacing. The component utilizes a polyphenylene sulfide (PPS) insulator body rated UL 94V-0, supporting nominal PCB thicknesses of 0.062 inches (1.57mm). Operating within a temperature range of -40°C to +125°C, it offers a maximum current rating of 3A and insulation resistance of 5 GOhms minimum.

Edgeboard Connectors Feature Summary

• High-temperature PPS insulator body ensures stability in demanding thermal environments
• Female cantilever contacts provide reliable signal transmission with gold plating
• Single-row configuration accommodates standard 0.062-inch thick printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Medical equipment operating in elevated thermal conditions
• Communication infrastructure components

Edgeboard Connectors Procurement Notes

Verify the specific termination style and mounting flange configuration against the official datasheet before ordering. Confirm that the selected variant matches the required PCB thickness tolerance of 0.062 inches. Ensure compatibility with existing panel mounting hardware and check for any specific environmental certifications such as RoHS compliance relevant to the project requirements.

Edgeboard Connectors Selection Notes

Select this connector when high-temperature performance is critical, as indicated by the PPS material and 125°C upper limit. The 21-position count suits moderate-density interconnect needs. Consider the single-row layout for space-constrained vertical installations. Evaluate the cantilever contact type for appropriate insertion force characteristics relative to the mating board design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 887 series, which specializes in high-temperature card edge connectors. The series distinguishes itself through the use of polyphenylene sulfide insulators, offering superior thermal resistance compared to standard materials. The 887 series provides various termination and mounting options to support diverse industrial and commercial electronic assembly requirements.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 837/887 Series Ordering Guide for verified substitute part numbers. Cross-reference pin counts, pitch dimensions, and termination styles to ensure mechanical and electrical compatibility. Verify that alternative parts meet the same high-temperature ratings and material specifications.
