M80-8420742

Overview

The M80-8420742 is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a single row with 7 positions and a 2mm (0.079 inch) mating pitch. Designed for through-hole mounting, this right-angle connector utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the termination posts. The housing is constructed from black, glass-filled PPS material rated UL94 V-0. It supports a maximum voltage of 120V and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Right-angle through-hole design for compact board-to-board or cable connections
• Gold-plated contact surfaces ensure reliable signal transmission
• Robust mechanical resistance against shock, bump, and vibration
• High-temperature resistant PPS insulation material

Applications

• Industrial control systems requiring high vibration resistance
• Automotive electronics operating in extreme temperatures
• Compact consumer devices needing space-saving right-angle headers
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific ordering suffix to confirm the exact contact finish configuration, as variations exist between gold/tin and other combinations. Ensure compatibility with the corresponding female socket series for proper mating. Confirm that the right-angle orientation aligns with the PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to the end product. Validate the current component status to avoid obsolescence risks during production.

Selection Notes

Select this model when a single-row, right-angle male header is required for tight spatial constraints. The 2mm pitch allows for dense pin arrangements while maintaining adequate spacing. Consider the 120V rating and 3A current capacity for low-power signal applications. The through-hole termination provides strong mechanical anchoring compared to surface mount alternatives. Ensure the mating partner matches the Datamate L-Tek series specifications.

Part Context

This component belongs to the Datamate L-Tek family, known for its durability and compact form factor. The M80-842 series specifically offers right-angle options for versatile PCB integration. As a male header, it pairs with female sockets to create secure interconnects. The design emphasizes reliability in harsh environments, making it suitable for demanding industrial and automotive sectors where consistent performance is critical.

Replacement Considerations

Direct substitutes within the same series include M80-8420642 (6-position) and M80-8420842 (8-position) for similar right-angle configurations. For vertical orientations, consider M80-841 variants. Always verify that any replacement maintains the 2mm pitch and single-row structure to ensure mechanical and electrical compatibility.
