Overview
The M20-7872446 is a board connector socket assembly manufactured by Harwin. It features 48 contacts arranged in two rows with a 0.1 inch (2.54 mm) pitch. The component utilizes surface mount terminals and includes a black insulator housing. Electrical specifications include a dielectric withstand voltage of 600VAC, contact resistance of 20 mΩ, and insulation resistance of 1 GΩ. The maximum insertion force is rated at 2.0016 N. The contacts are terminated with tin plating over a nickel barrier.
Feature Summary
- Dual-row configuration designed for high-density board-to-board applications
- Surface mount terminal style facilitates automated PCB assembly processes
- Tin-plated contacts with nickel barrier ensure reliable electrical connections
Applications
- High-density electronic assemblies requiring compact form factors
- Board-to-board interconnection systems
- Industrial control modules with space constraints
Procurement Notes
Verify the specific RoHS compliance status through official manufacturer documentation prior to integration, as regulatory details may vary by production batch. Confirm that the surface mount termination type aligns with your facility's reflow soldering profiles. Ensure the 48-contact layout matches your PCB footprint design requirements exactly.
Selection Notes
Select this component when a dual-row, 48-position socket is required for surface mount technology. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the 600VAC rating and 20 mΩ contact resistance for signal integrity needs. Verify that the black insulator material meets your thermal and mechanical environment standards.
