837-048-555-207

Edgeboard Connectors Overview

The EDAC Inc. part number 837-048-555-207 is a standard card edge connector from the 837 High Temp Series. It features 48 positions with a 0.156-inch (3.96mm) contact spacing. Designed as a dual-edge receptacle, it accommodates non-specified dual-sided cards. The connector utilizes gold-plated copper alloy contacts and a green diallyl phthalate (DAP) insulator. It supports through-hole mounting with wire wrap termination. The unit operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female receptacle design for secure connection to double-sided circuit boards
• High-temperature resistant construction using diallyl phthalate insulation material
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Wire wrap termination method provides robust mechanical stability for through-hole installation

Edgeboard Connectors Applications

• High-temperature industrial control systems requiring durable interconnects
• Automotive electronics applications subject to thermal stress
• Aerospace and defense equipment utilizing standardized card edge interfaces
• Telecommunications infrastructure hardware demanding long-term reliability

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and flange configuration. Ensure compatibility with target PCB stack-up dimensions and hole patterns. Confirm RoHS3 compliance status matches project requirements. Cross-reference the manufacturer datasheet for precise mechanical tolerances before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when dual-sided card insertion is required alongside high thermal endurance. The 0.156-inch pitch suits larger board layouts where space constraints are less critical than durability. Verify that the wire wrap termination aligns with available assembly tools and processes. Consider the green DAP housing for visual identification in complex assemblies requiring distinct connector differentiation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 837 series, engineered for demanding environments. The series emphasizes high-temperature performance and mechanical ruggedness. The 837-048 variant specifically addresses applications needing higher density connections on dual-edge boards while maintaining the series' established reliability standards and material specifications.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 837/887 Series Ordering Guide for verified substitute part numbers. Direct replacements must match the 48-position dual-edge configuration and 0.156-inch pitch. Ensure any alternative maintains identical termination style and operating temperature range for seamless integration.
