Proximity sensors employ a sensing technology to detect the presence of an object without physical contact. They are mainly used in automated production lines, industrial robots and aerospace applications, and are typically categorized into inductive, capacitive, ultrasonic and optical types. Among them, the inductive proximity sensor is the most widely used, which consists of two coils and a core. The ZX-EM02HT is picked as an example of inductive proximity sensors, of which the application fields and working principles are discussed as below.

The ZX-EM02HT inductive proximity sensor mainly applies to the detecting, positioning and speed measurement of metal objects in auxiliary equipment and automated production lines. It is frequently mounted in various machinery and devices to detect the presence of metal objects, such as machine tools and robots in industrial automation, as well as cars and aircrafts in transportation. For these applications, the environment wherein the ZX-EM02HT inductive proximity sensor is often put may have dust, moisture, strong vibration, and high temperature. Therefore, the ZX-EM02HT is featured with high dust and waterproof protection, with an IP67 rating, as well as EMC strenghtened shielding and robust operating temperature range from -25℃ to 75℃.

In terms of working principle, the ZX-EM02HT employs the eddy currents induced by the proximity of a metal object to produce a detectable voltage signal that can be amplified. It has four core components -- the oscillator circuit, the coil, the amplifier-mixer, and the detector circuit. When the ZX-EM02HT is powered on, the oscillator circuit produces an alternating current in the coil, making the coil acts as transmitter. If a metal object approaches the coil, an eddy current will be generated in the object’s metal by electromagnetic induction, and the eddy current will also induce a voltage in the coil. Such a voltage signal is amplified by the amplifier-mixer and then detected by the detector circuit, triggering the output switching signal from low to high.

In conclusion, the ZX-EM02HT is an inductive type proximity sensor with wide application fields and a straightforward operating principle, which makes it widely used in various industries. Its dust and waterproof design as well as EMC strengthened shielding and temperature resistance allows it to operate reliably in most environments.
