M80-8502042

Overview

The Harwin M80-8502042 is a 20-position, double-row receptacle connector from the Datamate L-Tek series. It features a 2.00mm (0.079") pitch and is designed for board-to-board or cable connections via through-hole solder termination. The unit utilizes female socket contacts with gold plating on the mating interface and tin plating on the tail. Rated for 800V, it operates within a temperature range of -55°C to 125°C. Key physical dimensions include an insulation height of 5.14mm and a stacking height of 7.23mm or 7.85mm depending on configuration.

Feature Summary

• High-reliability four-finger beryllium copper contacts ensure connection integrity under vibration and shock.
• Locking slide mechanism provides secure retention during mating cycles.
• Robust nylon 4/6 insulation material offers UL94 V-0 flammability rating.

Applications

• Automotive electronic systems
• Military equipment interfaces
• General industrial control boards

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm contact count, row configuration, and plating specifications. Ensure compatibility with mating pin headers regarding locking mechanisms and stacking heights. Cross-reference datasheets for environmental ratings and termination requirements before integration.

Selection Notes

Select this component when high-density interconnects are required in harsh environments. The 2.00mm pitch allows for compact layouts while maintaining robust mechanical stability. Consider the through-hole mounting style for superior mechanical strength compared to surface mount alternatives in high-vibration applications.

Part Context

This connector belongs to the Datamate L-Tek family, engineered for safety-critical applications. The series is characterized by its durability against high loads, shock, and acceleration. It supports repeated mating cycles without performance degradation, making it suitable for demanding operational conditions.

Replacement Considerations

Direct substitutes within the same series include M80-8501442 (14-position) and M80-8502042 variants with different pin counts. Verify that alternative parts match the 2.00mm pitch, double-row layout, and through-hole termination style to maintain mechanical and electrical compatibility.
