Molex Pin Header, Gold Contact Plating, 250V Voltage Rating - KK 254 Series - 22-29-2021

This two-contact pin header from Molex gives you high-quality wire-to-board connections without overcrowding a busy PCB. It's unshrouded, meaning there's no plastic wall around the contacts, so it takes up minimal space. For flexible use, the standardised 2.54mm pitch is compatible with most breadboards. The sturdy nylon housing material resists wear and abrasion, so this hardy device can cope with a challenging environment. Gold-plated brass contacts are highly conductive and corrosion-resistant for long-lasting, reliable connectivity.
