Overview
The M20-7890546 is a 5-position socket assembly from the Harwin M20 series. It features a single row of contacts with a 2.54 mm (0.1 in) pitch. The connector utilizes through-hole, right-angle termination for vertical board mounting. Contact plating consists of gold and tin finishes to ensure reliable signal transmission and corrosion resistance. The housing is constructed from nylon, providing mechanical stability and electrical insulation.
Feature Summary
- Right-angle through-hole mounting design for compact vertical integration
- Dual metal plating system combining gold and tin for enhanced durability
- Single-row configuration supporting standard 2.54 mm grid spacing
Applications
- Vertical interconnects on printed circuit boards
- Signal routing in industrial control modules
- Connector interfaces for electronic test equipment
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official Harwin documentation. Confirm that the received items match the specified five-position count and right-angle orientation. Ensure compliance with relevant environmental standards required for the specific application environment before final integration.
Selection Notes
Select this component when a low-profile vertical connection is required within a constrained PCB footprint. The right-angle form factor facilitates cable management and reduces the overall height profile compared to straight headers. Verify that the mating pin dimensions align with the 2.54 mm pitch specification to guarantee secure contact engagement.
Part Context
This receptacle belongs to the M20 series, which provides standardized connectivity solutions for general-purpose electronics. The series offers various position counts and termination styles to accommodate diverse board layout requirements while maintaining consistent mechanical and electrical performance characteristics across the product line.
Replacement Considerations
M20-7890546 is a discontinued item. Potential substitutes include M20-7890246 or other compatible M20 series sockets with matching pitch and termination types.
