Thus, if we discuss about different types of targets such as plastic target, metal target, and so on requires different types of proximity sensors such as capacitive proximity sensor or photoelectric proximity sensor, inductive proximity sensor, magnetic proximity sensor and so on. Misc. These inductive proximity sensors are available in AC, DC, and AC/DC modes (universal modes). Unlike the other sensors, proximity sensors can last for long life and have very high reliability as there are no mechanical parts as well as no physical contact exists between the sensor and sensed object. If the metal object (called as target, as we discussed earlier in this article) is moved towards the proximity sensor, then the eddy current will increase accordingly. If the metal object or target is moved away from the proximity sensor, then the amplitude of the oscillator will increase.
