837-064-544-208

Edgeboard Connectors Overview

The EDAC Inc. part number 837-064-544-208 is a high-temperature card edge connector from the 837 series, designed for reliable signal transmission in demanding environments. This component features a dual female configuration with 64 positions and a contact spacing of 0.156 inches (3.96 mm). It utilizes gold-plated contacts to ensure low resistance and durability, housed within a green diallyl phthalate (DAP) insulator. The connector supports through-hole mounting and wire wrap termination, accommodating board thicknesses typically associated with standard card edge applications.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration provides robust connection stability for double-sided circuit boards.
• Gold-plated contact surfaces enhance conductivity and resist corrosion over extended operational lifespans.
• High-temperature rated construction ensures performance integrity under elevated thermal conditions.
• Wire wrap termination method offers secure mechanical attachment and reliable electrical pathways.

Edgeboard Connectors Applications

• Industrial control systems requiring durable interconnects
• Telecommunications infrastructure equipment
• Automotive electronics modules
• Medical device instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 837 Series Ordering Guide to confirm exact pin count, plating thickness, and insulation material specifications. Ensure compatibility with target PCB hole sizes and wire wrap tooling standards before finalizing procurement orders to prevent integration issues.

Edgeboard Connectors Selection Notes

Select this component when a high-density, dual-sided card edge interface is required for high-temperature applications. Consider the 0.156-inch pitch and 64-position capacity relative to available board space. Confirm that the wire wrap termination style aligns with existing assembly processes and that the DAP insulator meets environmental compliance requirements for the intended deployment.

Edgeboard Connectors Part Context

This connector belongs to EDAC's 837 series, which specializes in high-temperature card edge solutions. The series is engineered for sectors where standard connectors may fail due to heat stress. The 837-064 variant specifically addresses needs for higher channel counts in dual-edge formats, maintaining consistent electrical characteristics across the full temperature range specified by the manufacturer.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 837 Series cross-reference documentation for verified substitute part numbers. Direct replacements must match the 64-position dual female layout, 0.156-inch pitch, and wire wrap termination style to ensure functional equivalence without redesigning the host PCB.
