M20-7893042

Overview

The M20-7893042 is a rectangular connector receptacle from the Harwin M20 series, designed for surface-mount technology. It features a 30-position configuration with a 2.54 mm (0.100 inch) pitch arranged in a single row. The component utilizes gold-plated contacts to ensure reliable signal transmission and low contact resistance. Constructed with a black polyamide (PA6T/Nylon 6T) housing rated UL 94 V-0 for flame resistance, it supports board-to-board or cable applications. The unit employs a jackscrew locking mechanism for secure mating and includes tin-plated tails for solder termination.

Feature Summary

• Jackscrew locking system provides secure mechanical retention during operation
• Gold-plated contact surfaces ensure high conductivity and corrosion resistance
• High-temperature resistant PA6T insulation housing meets UL 94 V-0 standards
• Right-angle surface mount design facilitates compact PCB integration

Applications

• Board-to-board interconnection systems
• Industrial control module interfaces
• Telecommunications equipment backplanes
• General purpose electronic assemblies requiring secure latching

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm orientation and pin count accuracy. Ensure that the procurement documentation explicitly references the M20 series specifications to avoid confusion with similar Harwin header variants. Cross-check the jackscrew mechanism availability as this feature distinguishes the part from standard push-pull connectors.

Selection Notes

Select this component when a right-angle SMT receptacle with positive locking is required for high-density layouts. The 2.54 mm pitch allows compatibility with standard 0.100 inch grid systems. Consider the thermal stability of the PA6T material for environments exceeding standard temperature ranges. Verify that the PCB footprint accommodates the jackscrew hardware clearance alongside the solder tail dimensions.

Part Context

This part belongs to the M20 series, a family of rectangular connectors known for robust mechanical performance. The series offers various configurations including headers and receptacles with different locking mechanisms. The M20-7893042 specifically addresses needs for secure, right-angle connections where vibration resistance is critical compared to non-latching alternatives.

Replacement Considerations

Direct substitutes must match the 30-position count, 2.54 mm pitch, right-angle orientation, and jackscrew locking style. Generic equivalents may lack the specific UL 94 V-0 rating or gold plating thickness. Verify that any replacement maintains the same housing height and tail length for proper solder joint formation.
