Harwin M22 Series Straight Through Hole Pin Header, 16 Contacts, 2 mm Pitch, 2 Row, Unshrouded, Gold Plated, M22-2020805

The Harwin M22-2020805 is a straight, through-hole pin header from the M22 Series, engineered for dense board-to-board connections in electronic systems requiring reliable signal transmission. With a compact 2 mm pitch, this header is designed to maximize PCB space while offering a robust interconnection solution, making it particularly well suited for embedded computing and industrial automation platforms.

This pin header features 16 gold-plated contacts arrayed in two rows, optimizing both electrical performance and mechanical reliability. Its unshrouded format allows for flexibility in stacking and mating with compatible sockets or jumpers. The phosphor bronze contacts, finished with gold plating, ensure consistent conductivity and are resistant to oxidation, delivering long-term durability even in high-frequency or high-cycle applications.

The housing is constructed from high-temperature thermoplastic nylon, enabling the connector to endure reflow soldering without deformation or loss of integrity. It is optimized for soldered PCB assembly, with a tail pin length of 3.4 mm and a mating pin length of 3.5 mm to support secure engagement with complementary connectors. The construction also incorporates features such as castellations, allowing for size customization where required.

This header is rated for a current of 1 A per contact and withstands working voltages up to 500 V, accommodating both signal and low-power needs. The connector is rated for reliable operation within an ambient temperature range of -40°C to 105°C, suitable for use in industrial, automotive, or consumer environments where resilience to thermal stress is essential.

Harwin M22 Series pin headers are commonly used in applications such as embedded PCs, motherboards, industrial controllers, communication modules, drives, monitoring systems, and a variety of personal computing and commercial electronics. The connector’s design allows it to mate with compatible M22 series sockets, housing, and jumpers, ensuring versatility across multiple designs.

Engineers and designers benefit from the M22-2020805’s multiple configuration options, its robust construction for reflow soldering compatibility, and the ability to cut the header to custom lengths due to castellated housing features. This flexibility is critical for small-scale or prototype runs and for integration into complex, modular system designs.
