Overview
The M20-7891946 is a 19-position single-row header connector from the Harwin M20 series. It features a 2.54 mm (0.100 inch) pitch and is designed for through-hole mounting on printed circuit boards. The component utilizes square pin contacts with tin plating to ensure reliable electrical connections. This straight-style connector is intended for board-to-board or cable applications, providing a secure mechanical interface within electronic assemblies.
Feature Summary
- Single-row configuration with 19 positions
- Through-hole termination for PCB mounting
- Tin-plated square pin contacts
- Standard 2.54 mm spacing
Applications
- Board-to-board interconnections
- Cable-to-board wiring systems
- Industrial control panel assembly
- General electronic equipment integration
Procurement Notes
Verify the specific contact length and housing material against the official datasheet before procurement. Confirm that the tin plating specification meets the environmental requirements of the target application. Ensure compatibility with mating female receptacles from the same M20 series family to guarantee proper engagement and electrical performance.
Selection Notes
Select this component when a single-row, through-hole header with tin contacts is required. The 19-position count suits moderate density layouts. Consider the M20 series' robust construction if high reliability is needed. Verify that the straight orientation fits the mechanical constraints of the enclosure design.
Part Context
This part belongs to the M20 series, which offers industrial-grade connectors with durable double-beam contacts. The series supports various row counts and terminations, designed for high-density PCB applications. The M20-7891946 represents the standard through-hole variant within this versatile product line.
Replacement Considerations
M20-7891942 is a compatible alternative featuring gold plating instead of tin. Both parts share the same 19-position count, 2.54 mm pitch, and through-hole mounting style. Select the gold-plated version if enhanced corrosion resistance is required.
