HARWIN M20 Series Straight Through Hole Pin Header 4 Contacts 2.54 mm Pitch 1 Row Unshrouded M20-9990445

HARWIN M20-9990445 is a straight through hole pin header connector from the M20 series featuring 4 contacts arranged in a single row with a 2.54 mm pitch. Manufactured with a nylon housing capable of withstanding reflow soldering processes, this unshrouded male pin header offers durable, high-quality PCB interconnection.

The pins utilize brass as the base material with gold plating to ensure superior conductivity and corrosion resistance, making this connector reliable for demanding industrial and electronic applications. It mounts through the PCB with a tail pin length of 3 mm, supporting secure solder termination, while the mating pin length of 6.1 mm ensures firm connectivity with mating components.

This connector operates effectively from a minimum temperature of -40°C up to a maximum of 105°C, making it suitable for applications in consumer electronics, industrial monitoring, communications, and embedded computing systems. The flexible design allows it to mate with various M20 series sockets and jumpers, providing versatility for board-to-board and wire-to-board connections.

The pin header housings incorporate castellations enabling them to be cut to size if required, although care should be taken to avoid damaging the tails during modification. The product is ideal for embedded PCs, motherboards, and other large electronics systems where standard reliable connectivity is needed.
