Potentiometer Membrane Magneto Pot 50mm

The Magneto Pot was designed as simple, yet elegant in its ability to track motion in a contactless manner. This Magneto Pot potentiometer comes with a magnet inside of a cylinder, or a magnet on the opposing side of a motion device. This magnet will guide the built-in magnetics of the Magneto Pot for position location through a potentiometric output. The Magneto Pot is basically a sealed potentiometer, in the membrane potentiometer tradition. Thus it does not require any wiper/actuator to connect the collector and the resistor. Instead, an outside magnet in this module controls the Magneto Pot, which attracts the magnetic forces within the Magneto Pot to connect to the linear resistor and give linear potentiometer feedback.

The wiper inside the sealed pot is magnetic or ferromagnetic, and will only perform if connected with an exterior magnet. As opposed to a magnetically-based Reed Switch, which gives simply “open” or “close” signals, the Magneto Pot gives the full linear travel of a hydraulic or pneumatic cylinder. Basically, in liquid level applications, the Magneto Pot attaches to the outside of a liquid tank.  And thus gives the position of the magnet inside the float. No water ingress, no wearing of the part by environment, because the Magneto Pot is outside of the tank.

The MagnetoPot is made up of polyester, fiberglass, and Kapton, depending on the specification/ application required. Moreover, it functions as a voltage divider, a resistor, or rheostat, as desired by the end-user. By bringing the exterior magnet into proximity necessary to connect with the internal magnetic attractors, the operator can obtain linear position sensing based on the location of the exterior magnet. As the exterior magnet moves, so does the electrical output of the Magneto Pot. Finally, the Magneto Pot should not be mounted to a ferromagnetic surface.
