Product Description

HARWIN M20-9990446 is a high-quality straight through hole pin header connector with 4 contacts arranged in a single row at 2.54 mm pitch. It features an unshrouded nylon housing capable of withstanding reflow soldering temperatures, making it suitable for mass production PCB assembly processes.

The connector is designed for board-to-board and wire-to-board connections in embedded PCs, motherboards, consumer electronics, communications, industrial controls, and other electronic applications. The brass contacts plated with tin ensure reliable electrical performance and durability under mechanical stress.

With a current rating of 3A and an operating temperature range from -40°C to 105°C, this pin header functions well under a wide range of environmental conditions. The tail pins extend 3 mm for through-hole mounting, while the mating pins have a length of 6.1 mm to provide secure mate with complementary connectors.

Construction includes features such as castellations allowing size customization by cutting; care should be taken to avoid damaging the tail pins during modification. The unshrouded, straight orientation design enables versatile integration into various PCB layouts.

The connector housing is made of high-temperature nylon to endure reflow soldering. Four brass contacts provide a robust electrical interface supporting 3A current. 2.54 mm pin pitch matches industry-standard spacing for PCB connectors.

Operating temperature specifications allow use in harsh industrial environments. Pin lengths are optimized for secure solder joints and mating connection retention. The design supports board-to-board and wire-to-board connector systems.

This product is ideal for embedded systems, consumer electronics, and industrial control applications.
