837-082-540-212

Edgeboard Connectors Overview

The EDAC Inc. 837-082-540-212 is a dual-edge female card edge connector from the High Temp Series, designed for through-hole mounting with wire wrap termination. It features 82 positions arranged in two rows of 41 contacts, utilizing a 0.156-inch (3.96mm) spacing. The connector supports PCB thicknesses between 0.054 and 0.070 inches. Contacts are made of copper alloy with a 10.0µin gold plating. The insulator is green thermoplastic polyester, rated for operation from -40°C to 125°C.

Edgeboard Connectors Feature Summary

• High temperature capability up to 125°C for demanding environments
• Wire wrap termination for secure board connection
• Dual-edge female contact configuration for double-sided cards
• Gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring high thermal stability
• Telecommunications infrastructure equipment
• Automotive electronics applications
• Aerospace and defense instrumentation

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct flange and pin count specifications. Confirm that the target application requires wire wrap termination rather than solder tail options. Check RoHS compliance status if restricted substances are mandated. Ensure PCB design accommodates the specified 0.156-inch pitch and dual-edge geometry. Validate thermal ratings against maximum operating temperatures.

Edgeboard Connectors Selection Notes

Select this component when high-temperature performance and wire wrap termination are required. The 82-position dual-edge format suits specific double-sided card designs. Compare against the 337 series if lower temperature ratings or different termination methods are acceptable. Ensure mechanical fit aligns with panel mounting requirements due to flange characteristics.

Edgeboard Connectors Part Context

This part belongs to the EDAC 837 High Temp Series, distinguished by its extended temperature range compared to standard connectors. It shares the 0.156-inch spacing common across many EDAC card edge products but differs in insulation material and thermal rating. The series targets rugged applications where standard connectors might fail under thermal stress.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations like 837-082-540-212 with different suffixes for minor mechanical changes. Cross-series replacements such as the 337 series require verification of temperature limits and termination type compatibility.
