Polarized

Polarized

Polarised connectors and headers provide a keyed, mating pair for power and signal in perf board and PCB projects. They help prevent incorrect or reversed connections, improving reliability in robotics, sensing, and embedded systems. The assortment covers male headers, female housings, and crimp pins, with a range of housing styles to fit common wiring harnesses and board footprints.

These parts integrate with standard tooling and assembly processes, offering dependable contact performance and resistance to vibration in real‑world use. They support clear polarity and consistent mating, making prototyping and final builds simpler and more robust, whether connecting sensors, actuators, or power rails across a compact harness.
