M80-7821742

Overview

The M80-7821742 is a Datamate L-Tek male plug connector from Harwin, designed for vertical through-board mounting. It features a single row with two contacts and utilizes four-leaf beryllium copper contacts suitable for high-speed data transmission. The connector employs a latched termination mechanism and offers a pin spacing of 2.54 mm. Contact areas are finished in gold to ensure reliable conductivity, while the PCB terminations feature a tin finish. This component supports large bore 22 AWG and small bore 24–28 AWG wire gauges, providing a robust solution for power and signal applications requiring secure mechanical retention.

Feature Summary

• Vertical through-board mounting configuration with latched termination
• Four-leaf beryllium copper contacts optimized for high-speed data transmission
• Gold-plated contact areas paired with tin-finished PCB terminations

Applications

• Power supply units
• Embedded systems
• Automotive solutions

Procurement Notes

Verify the specific ordering suffix against the official Harwin catalog to confirm contact count, orientation, and plating specifications. Ensure compatibility with mating female connectors within the Datamate series. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with the manufacturer's latest documentation to avoid discrepancies in packaging or accessory inclusion.

Selection Notes

Select this component when vertical board mounting and secure latching are required for two-circuit connections. The Datamate L-Tek series provides high durability and versatility for demanding environments. Consider the gold finish for corrosion resistance and the beryllium copper material for superior electrical performance. Evaluate space constraints as the vertical profile impacts PCB layout requirements compared to horizontal alternatives.

Part Context

This part belongs to the Harwin Datamate M80 series, a widely used connector family known for its versatility and durability. The M80 series serves as a popular solution for various industrial and commercial applications. The L-Tek variant specifically enhances mechanical stability and connection reliability. This series is distinct from other Harwin connector lines due to its unique latching mechanism and modular design capabilities.

Replacement Considerations

Compatible mating connectors include female counterparts from the same Datamate M80 series. Verify that replacement parts match the single-row, two-contact configuration and vertical orientation. Ensure the substitute maintains the same contact material and plating specifications for consistent performance.
