M80-7890442

Overview

The M80-7890442 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features a right-angle surface mount design with four positions arranged in two rows. The mating pitch is 0.079 inches (2.00mm). The contacts are made of phosphor bronze and are gold-plated for reliable conductivity. The housing is constructed from black polyphenylene sulfide (PPS) insulation. The component has a voltage rating of 120V and operates within a temperature range of -55°C to +125°C.

Feature Summary

Right-angle surface mount configuration for compact PCB integration
Gold-plated phosphor bronze contacts ensuring signal integrity
High-temperature PPS insulation material for thermal stability

Applications

Compact electronic device interconnects
Industrial control board connections
Consumer electronics internal wiring

Procurement Notes

Verify the specific datasheet version for the M80-7890442 to confirm RoHS compliance status and detailed mechanical dimensions. Ensure that the selected supplier provides traceability documentation matching the manufacturer's original part identification. Cross-reference the pin count and row configuration against the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, right-angle connection is required for space-constrained designs. The two-row layout maximizes contact density while maintaining a standard 2mm pitch. Consider the 120V rating and high-temperature tolerance when designing for environments with significant thermal loads or strict safety isolation requirements.

Part Context

This part belongs to the Datamate L-Tek series, known for its robust locking mechanisms and high reliability. The M80-7890442 specifically addresses applications needing a small form factor with secure surface mounting capabilities. It complements the broader Harwin connector ecosystem designed for demanding industrial and commercial sectors.
