Overview
The M20-7892746 is a single-row socket header from the Harwin M20 series, designed for through-hole mounting. It features a 2.54 mm pitch and contains 27 positions. The connector utilizes a black nylon housing and tin-plated contacts to ensure reliable electrical performance. Rated for 3 A current and 750 V voltage, it operates within a temperature range of -40°C to +105°C. This component serves as a horizontal free-hanging socket strip for board-to-board or wire-to-board interconnections.
Feature Summary
- Single-row configuration with 27 positions for compact circuit integration
- Through-hole solder pin termination for secure PCB attachment
- Tin-plated brass contacts housed in black nylon insulation
- Horizontal orientation design for flexible assembly layouts
Applications
- Industrial control system interconnects
- Consumer electronics internal wiring
- Test and measurement equipment interfaces
- General-purpose board-to-board connections
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and housing color variants. Check manufacturer lifecycle status as components may be subject to obsolescence. Ensure compatibility with mating pin headers regarding pitch and row count. Confirm RoHS compliance documentation is available for regulatory requirements.
Selection Notes
Select this part when a single-row, 27-position horizontal socket is required. Compare against vertical alternatives if space constraints differ. Verify that the 2.54 mm pitch matches existing board layout patterns. Consider the 3 A current rating against total load requirements across all positions.
Part Context
This component belongs to the M20 series, a widely used line of connectors by Harwin Inc. The series offers various configurations including pin strips and sockets in different row counts and orientations. The M20-7892746 specifically addresses needs for high-density single-row horizontal socket applications.
FAQ
