M20-7821442

Overview

The Harwin M20-7821442 is a 14-position single-in-line (SIL) vertical through-board socket assembly from the M20 series. It features a 2.54 mm (0.1 inch) pitch and utilizes selective gold plating on contact interfaces with tin plating on termination points. Designed for board-to-board connectivity, this component supports a rated current of 3A and operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T), ensuring UL94 V-0 flammability rating. The connector employs phosphor bronze contacts with square pin shapes, offering reliable mechanical retention and electrical performance in general-purpose applications.

Feature Summary

• Vertical through-board mounting configuration for standard PCB integration
• Selective gold and tin plating ensures corrosion resistance and reliable soldering
• High-temperature polyamide insulation provides thermal stability and safety compliance

Applications

• General-purpose board-to-board interconnections
• Industrial control systems requiring robust vertical headers
