M80-8050522

Overview

The M80-8050522 is a vertical connector header from the Harwin Datamate J-Tek series, designed for board-to-board or cable applications. It features a 2 mm (0.079 inch) mating pitch and houses 5 male pin contacts arranged in a single row. The connector utilizes a push-turn locking mechanism to ensure secure engagement. Contacts are constructed from phosphor bronze with gold plating on the mating interface and tin plating on the tail. The housing is made of black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0 for flammability. It supports through-hole termination and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Push-turn locking mechanism provides secure mechanical retention
• Gold-plated phosphor bronze contacts ensure reliable conductivity
• High-temperature PPS insulation material offers durability
• Vertical orientation facilitates compact board integration

Applications

• Industrial control systems requiring vibration resistance
• Automotive electronics harnesses
• Military and aerospace equipment
• General purpose power and signal interconnects

Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to confirm exact contact plating thickness, housing color variants, and locking style configurations. Ensure that the selected variant matches the required stacking height and terminal type specifications for the target PCB layout. Cross-reference the part number with current datasheets to confirm availability status and any recent design changes.

Selection Notes

Select this component when a robust, vertically oriented header with positive locking is required. The 2 mm pitch suits dense layouts while maintaining adequate spacing. Consider the push-turn lock for applications subject to shock or vibration where standard friction locks may fail. Verify that the 5-position count aligns with circuit requirements and that the through-hole termination method is compatible with the assembly process.

Part Context

This part belongs to the Datamate J-Tek family, known for high-reliability interconnects in harsh environments. The M80 prefix typically denotes headers within this ecosystem. These connectors are engineered for repeated mating cycles without performance degradation, utilizing four-finger beryllium copper or phosphor bronze contacts depending on the specific sub-series configuration.

Replacement Considerations

Compatible substitutes include other Harwin Datamate J-Tek headers with matching 2 mm pitch and 5 positions, such as M80-5T10642MC variants, provided the locking mechanism and termination style are identical. Ensure cross-compatibility with corresponding sockets before substitution.
