Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish. These switches send out high-frequency sound waves that target small areas, so the surface and structure of your object won't affect results like photoelectric sensors, which sense using light. This makes them great for materials with uneven surfaces, such as granules and powder. They also sense objects when obscured by smoke, dust, debris, or water, but they don't work as well where there's wind, since it could disrupt their sound waves. Once an object is detected or a set level is reached, the digital output sends a signal to your controller to turn components in your system on or off. Use their plug to quickly connect and disconnect to cables with a socket (sold separately). UL listed, C-UL listed, and CE marked, all meet American, Canadian, and European safety standards.

Switches with two outputs let you set a minimum level on one output and a maximum on the other—for example, you can keep liquid levels constant by turning on a pump when the level drops too low and turning off the pump when it reaches the maximum.

Switches with PNP/NPN signal output automatically produce the signal you need based on the connected device.

90° elbow switches are compact to fit in tight spaces. They’re best for conveyors.

Rated IP67, all of these switches seal out dust and water if briefly submersed. NEMA 6 rated switches also stand up to weather and washdowns.

The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity. Change the color to show different process statuses. For more visibility, change the intensity of the color or choose a light pattern. These switches can flash, rotate, and show other patterns, all at speeds you can control. To change how much force they need to actuate, alter the sensitivity. With a high sensitivity, they’ll actuate even if you’re wearing gloves. With a low sensitivity, they’re more resistant to accidental actuation.

To program your switch, download the free Banner Pro Editor Software. You’ll need a switch programming kit (sold separately) to connect your switch to the software.

Switches with a copolyester base are FDA compliant for incidental food contact once installed.

Switches with an audible alarm can be programmed to 12 different tones ranging from sirens to melodies.
