M80-8542042

Overview

The Harwin M80-8542042 is a Datamate L-Tek socket connector featuring 20 contacts arranged in two rows with a 2.00 mm pitch. It utilizes through-hole termination for PCB mounting and operates within a temperature range of -55°C to +125°C. The housing is black, rated at 800V, and constructed from material meeting UL94 V-0 flammability standards. Contact finishes include gold plating on the mating interface and tin on the post. Designed for board-to-board or wire-to-board applications, it supports stacking heights of 7.23 mm and 7.85 mm.

Feature Summary

• High-reliability four-finger beryllium copper contact technology ensures connection integrity under vibration and shock.
• Lock pin slide mechanism provides secure mechanical retention during mating cycles.
• Durable design withstands high mating cycles without performance degradation in harsh environments.

Applications

• Board-to-board interconnections requiring high reliability
• Wire-to-board connections in industrial systems
• Applications subject to high load vibrations and shocks

Procurement Notes

Verify that the specific part number corresponds to the version without locking latches, as indicated by official Harwin documentation. Confirm that the required stacking height matches the available options of 7.23 mm or 7.85 mm. Ensure compatibility with the corresponding male header series for proper mating. Check for any specific environmental certifications required for the target application before finalizing procurement.

Selection Notes

Select this component when a 20-position, 2-row socket is needed with a 2.00 mm pitch. It is suitable for applications demanding high durability against mechanical stress. Consider the absence of integrated locking latches if external retention is preferred. Verify that the 800V rating and current capacity meet the circuit requirements. Ensure the through-hole mounting style aligns with the PCB design constraints.

Part Context

This component belongs to the Harwin Datamate M80 series, known for robust performance in safety-critical applications. The L-Tek variant emphasizes high-reliability contacts designed for extreme conditions. It serves as a counterpart to male headers within the same ecosystem, facilitating secure interconnects in demanding industrial and aerospace environments where standard connectors may fail.

Replacement Considerations

M80-8532042 is a confirmed substitute part number that includes locking latches. Verify if the presence of latches affects the mechanical fit or function in the existing assembly. No other direct substitutes are documented in the provided sources.
