A Perfect Match

Sensors use the reed switch as the heart of their switching mechanism. When paired with a permanent magnet they are an ideal method of sensing and detecting metal, movement, proximity, and liquid level and flow.

Limit Switching

Spot On™ Leverless Limit-Switches are designed to handle the most extreme operating environments. The four different Spot On™ models can sense farther, work faster and last longer than the competition.

Steel Sensors

Our full line of ferrous metal sensing proximity sensors are the perfect fit for applications where space is at a premium. Since no actuator is required, the overall footprint of the sensor is greatly reduced.

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.
