Sparkfun MagnetoPot Linear Potentiometer - 50mm (Male Pins)

The MagnetoPot Linear Potentiometer - 50mm (Male Pins) offers a seamless solution for tracking motion without physical contact. Utilizing internal magnetics, it detects position through a potentiometric output, guided by an external magnet. This sealed potentiometer operates without a traditional wiper or actuator, providing reliable linear feedback by connecting a linear resistor with magnetic forces.

Ideal for applications requiring precise motion tracking, it can be used in hydraulic or pneumatic systems to provide full linear travel data. Unlike Reed Switches, which only indicate open or closed states, it offers continuous feedback over the entire range of motion.

In liquid level measurement, the device can be mounted externally on a tank. It accurately tracks the position of a magnet within a float, ensuring no water ingress and protecting the component from environmental wear, as it remains outside the tank. This innovative approach not only extends the lifespan of the potentiometer but also maintains accuracy and reliability in demanding conditions.
