Overview
The Harwin M20-7821746 is a single-row, vertical receptacle connector designed for through-hole mounting. It features 17 positions with a 2.54 mm (0.1 inch) pitch. The connector has a current rating of 3A and a voltage rating of 1000V. The housing is constructed from Polyamide (PA6T) or Nylon 6T, while the contacts are tin-plated. This component belongs to the M20 series, which utilizes high-temperature liquid crystal polymer for enhanced durability and SMT reflow compatibility.
Feature Summary
- Single row vertical design for space-efficient PCB integration
- High voltage insulation capability up to 1000V
- Durable polyamide housing material resistant to thermal stress
Applications
- General purpose electronic assemblies
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the specific insulation material variant (Polyamide PA6T vs. Nylon 6T) as specifications may vary by production batch. Confirm that the tin-plated contact finish meets the required solderability standards for the intended assembly process. Ensure the through-hole footprint matches the target PCB design guidelines for reliable mechanical retention.
Selection Notes
Select this part when a single-row, vertical female connector is required for board-to-board or cable connections. The 17-position count suits moderate density applications. Consider the 1000V rating if operating in high-voltage environments. Verify that the through-hole installation method aligns with the manufacturing capabilities of the production line.
Part Context
This component is part of the Harwin M20 series, a family of 2.54 mm pitch PCB connectors. The series includes both single and double-row variants in various lengths. The M20 series is characterized by its compact form factor and robust construction, suitable for demanding industrial and telecommunications applications requiring reliable interconnection solutions.
