Simply put, we are a company that produces sensor products. But, we are much more than that. We are the catalyst that helps drive innovation in virtually any, and every industry by helping to transform mechanical motion into electrical signals. When a company has an engineering sensor challenge, we are the first they turn to help ensure that their project is a success.


Our Story

HSI Leadership
David Posey, Travis Posey, Ryan Posey

William Posey wasn’t just an entrepreneur. He was an engineer. And he didn’t just start a company. He pioneered a technology…one that over the years has made a lot more technology possible, in everything from pacemakers to pilot ejection seats and security systems to space stations.

The reed switch that Posey helped perfect has evolved over four decades—we’ve made sure of that. But it’s still one of the safest, greenest and most responsive sensing solutions in the world. William Posey pioneered it, and—under the leadership of his son David – CEO and chief technology officer, and his grandsons, Ryan – president, and Travis – vice president of business development—HSI Sensing continues to perfect it every day at our 55,000-square-foot facility in Chickasha, Oklahoma.

Innovative Technical Culture

We are constantly looking to reimagine the way we use sensor technology in our everyday lives. Whether our engineers are looking at a chemical processing plant, a fighter jet or a pinball machine, we are imagining the way that we can use our products to make those technologies better. We encourage imagination and innovation because we love seeing our customers projects become a success. The only question is how can we help with your next innovation?
