M80-8520642

Overview

The Harwin M80-8520642 is a Datamate L-Tek series connector header designed for vertical through-hole mounting. It features a 6-position configuration with a 2.00mm pitch and single row arrangement. The component utilizes phosphor bronze contacts with selective gold plating on the mating interface and tin plating on the tail, rated for 120V and 3A current. Constructed from black PPS insulation reinforced with glass fiber, it operates within a temperature range of -55°C to 125°C. The unit includes a cover and employs a push-turn locking mechanism for secure board-to-board or cable connections.

Feature Summary

• Datamate L-Tek series construction utilizing high-reliability four-finger beryllium copper alloy contacts to ensure connection integrity in harsh environments.
• Push-turn locking mechanism provides secure attachment for applications subject to high vibration, shock, and acceleration.
• Selective contact plating combines durable gold on mating surfaces with tin on termination tails for optimized electrical performance.
• Integrated cover design protects contacts while maintaining compatibility with panel-mounted receptacles.

Applications

• Board-to-board interconnects in industrial control systems
• Cable-to-board connections requiring robust mechanical retention
• Equipment operating under high vibration or shock conditions
• Harsh environment electronic assemblies demanding high durability

Procurement Notes

Verify that the specific part number M80-8520642 corresponds to the Datamate L-Tek series rather than J-Tek variants, as both share similar numbering structures but differ in technical specifications. Confirm the presence of the push-turn locking feature and the specific contact plating combination (gold/tin) required for your application. Ensure the vertical through-hole orientation matches your PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a vertical, latched header is required for reliable signal transmission in demanding environments. The Datamate L-Tek series offers superior durability compared to standard connectors due to its specialized contact design. Consider the 2.00mm pitch and 6-position count to ensure adequate space on the target PCB. Verify that the 120V rating and 3A current capacity meet the circuit's operational demands without exceeding thermal limits.

Part Context

This connector belongs to the Datamate L-Tek family, which is engineered for safety-critical and high-load applications. Unlike standard headers, this series emphasizes mechanical resilience against physical stressors like shock and acceleration. The M80-8520642 variant specifically addresses needs for vertical mounting with secure locking, distinguishing it from surface-mount or unlatched alternatives within the broader Harwin portfolio.

Replacement Considerations

Compatible substitutes include other Harwin Datamate L-Tek headers with matching 6-position counts and vertical orientations, such as M80-8520642 variants with different plating options. Cross-series replacement with Datamate J-Tek models requires verification of locking mechanisms and temperature ratings, as these families exhibit distinct performance characteristics and environmental tolerances.
