Unsurpassed In-House Capabilities

We can tailor a standard product or start from scratch with a new magnetic design to solve for low and high frequencies, power inductors and common mode choke needs.


Customers often pair our actuators with our proximity sensors for a matching magnetic sensor package. Also, many of the actuator housings provide a way to mount the magnet onto a surface.


We offer magnets in four different shapes: square, rectangular, disc and cylindrical. HSI Sensing magnets also come in different dimensions, gauss strengths and material composition.

Below is just a sampling of our 1500+ products to choose from with various options available for customization, including switching and range. All HSI products can be modified to your specifications.
