887-070-541-804

Edgeboard Connectors Overview

The EDAC 887-070-541-804 is a high-temperature standard card edge connector receptacle from the 887 series. It features 70 positions arranged in a double row with a 3.96 mm pitch and supports PCBs of 1.57 mm thickness. The unit utilizes gold-plated copper alloy contacts for reliable signal transmission and a Polyphenylene Sulfide (PPS) insulator rated UL 94V-0. Designed for panel mounting, it offers a vertical orientation with a maximum operating temperature of +125°C and a minimum of -40°C, ensuring stability in demanding thermal environments.

Edgeboard Connectors Feature Summary

• High-temperature PPS insulator material ensures structural integrity and electrical performance under elevated thermal conditions.
• Gold-plated copper alloy contacts provide low contact resistance and corrosion resistance for durable connections.
• Double-row configuration accommodates 70 positions within a compact footprint defined by 3.96 mm spacing.
• Panel mount design with vertical orientation facilitates secure integration into chassis or enclosure systems.

Edgeboard Connectors Applications

• Industrial control systems requiring stable connectivity under thermal stress
• Telecommunications equipment utilizing high-density card edge interfaces
• Automotive electronics modules needing robust environmental resistance
• Test and measurement instrumentation with precise signal routing requirements

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before ordering. Confirm that the housing material is Polyphenylene Sulfide to ensure compliance with high-temperature operational specifications. Check for any RoHS compliance documentation if environmental regulations apply to your project. Ensure that the panel mounting style aligns with your mechanical assembly constraints. Validate that the contact plating specification meets your conductivity and durability needs.

Edgeboard Connectors Selection Notes

Select this component when a double-row card edge interface is necessary for high-density applications. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches, reducing manufacturing complexity. The vertical panel mount style simplifies wiring access in enclosed spaces. Consider the PPS material properties for environments exceeding standard plastic temperature limits. Ensure the PCB thickness of 1.57 mm is compatible with your board design to guarantee proper insertion force and retention.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 887 series, which specializes in high-temperature card edge solutions. The series distinguishes itself through the use of Polyphenylene Sulfide insulation, offering superior thermal stability compared to standard materials like DAP found in other series. The 887 series provides various termination options and mounting configurations to suit diverse industrial and commercial electronic packaging needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations in position count or termination style, such as 887-041-558-604 for single-row applications. Cross-series replacements may require evaluating pitch compatibility and housing material differences. Verify that any alternative maintains the 3.96 mm pitch and double-row layout to ensure mechanical fit without redesigning the host PCB.
