Molex KK 254 Series Straight Through Hole Pin Header, 2 Contacts, 2.54 mm Pitch, 1 Row, Unshrouded 22-27-2021

Molex 22-27-2021 KK 254 Series Straight Through Hole Pin Header is a high-quality electronic connector designed for efficient wire-to-board connections. Featuring 2 male contacts arranged in a single row with a compact 2.54 mm pitch, it is engineered to fit tightly on packed PCBs while maintaining reliable electrical contact.

The pin header is constructed with a robust nylon housing that provides excellent tensile and compressive strength, protecting the terminals from mechanical stresses. Its brass contact pins are tin-plated to resist corrosion, ensuring long-term durability and consistent conductivity in demanding industrial and commercial environments.

Rated for a maximum current of 4 amperes and a voltage tolerance of up to 500 volts, this unshrouded header supports a wide range of low current applications. The through-hole mounting and solder termination type facilitate straightforward and secure PCB assembly.

This connector performs reliably across a broad temperature spectrum from -40°C to 105°C, making it suitable for use in automotive equipment, consumer electronics, communication devices, and medical technology instruments.

Moreover, the header is designed to mate perfectly with Molex crimp terminal housings, such as those in the 2695 and 6471 series with locking ramps, and the 7880 series high-pressure housings, offering a versatile connection solution.
