When Only The Best Will Do

HSI Sensing has been meeting the unique challenges of aerospace sensors for more than 50 years, providing mission-critical solutions for everything from seat belt connections and shock sensing to fluid level monitoring and wing positioning. Our outstandingly reliable products can handle millions of cycles in applications and hermetically sealed switches ensure safety no matter where they are applied. In fact, our sensors are so precise that we can detect 1/100 of an inch of movement to individual degrees of rotation.

Our AS9100 certification ensures that when we take on your aerospace project, you can be confident in our credentials.
