Overview
The Harwin M20-7890246 is a 2-position right-angle through-hole socket header from the M20 series. It features a 2.54 mm pitch and utilizes nickel-plated tin contacts made of bronze for reliable conductivity. The housing is constructed from nylon, providing structural integrity within an operating temperature range of -40°C to 105°C. Designed for board-to-board connections, this single-row receptacle supports up to 12A current capacity and complies with RoHS standards.
Feature Summary
- Right-angle orientation facilitates compact vertical mounting configurations on printed circuit boards.
- Through-hole termination ensures secure mechanical attachment and robust solder joint formation.
- Nylon insulation material offers durability and resistance to thermal stress during operation.
Applications
- Board-to-board interconnections in electronic assemblies
- Industrial control system wiring interfaces
- Consumer electronics internal component linking
Procurement Notes
Verify the specific part number M20-7890246 against official Harwin documentation to confirm compatibility with design requirements. Ensure that the right-angle configuration and through-hole termination meet the physical constraints of the target application. Cross-reference technical specifications such as current rating and temperature limits before finalizing procurement decisions.
Selection Notes
Select this component when a low-profile, right-angle connection is required for two-pin circuits. The 2.54 mm pitch aligns with standard PCB grid layouts, simplifying design integration. Consider the 12A current rating and nylon housing properties to ensure suitability for the intended electrical and environmental conditions.
Part Context
This connector belongs to the M20 series by Harwin, known for high-density rectangular connectors. The series offers various configurations including surface mount and through-hole options. This specific model represents a basic two-position variant optimized for simple signal or power transmission needs in space-constrained environments.
Replacement Considerations
Consult Harwin's official substitution guide for verified equivalents. Generic alternatives may not match the precise pin spacing or contact plating specifications required for reliable performance in critical applications.
