The Low Power Non Magnetic Inductive Proximity Sensor is a Great way for Engineers, Makers, and DIYs to easily detect low permeability (non iron) metals such as aluminum. Why aluminum? Aluminum is widely available, inexpensive, very thin, and easy to apply. With a small piece of aluminum attached by tape or glue to almost anything, it can be detected by this Low Power Non Magnetic Inductive Proximity Sensor. Other low permeability metals such as copper can also be easily detected. This sensor is not to be confused with low cost magnetic sensors which obviously need magnets to operate. The Low Voltage Metal Sensor outputs a digital signal when a low permeability (non iron) metal is detected. This signal can be used to stop-start or change direction of something in motion or just turn a light off and on to indicate the presence of metal. Best of all no magnet is needed, and ...
