Frequently asked questions

What is an inductive proximity sensor?

An inductive proximity sensor is a non-contact switch that uses electromagnetic induction to detect the presence or absence of a metal object. It is commonly used in industrial automation and control systems to detect metal objects.

It works as follows: When a metal object enters the magnetic field generated by the sensor, eddy currents are generated in the object. These eddy currents create a reverse magnetic field that weakens the original magnetic field generated by the sensor. The sensor’s internal circuitry detects this change in the magnetic field and triggers the sensor’s output, indicating the presence of a metal object.

The advantages of inductive proximity sensors are that they do not require contact with the detected object, have fast switching time and high frequency (the switching frequency of our inductive proximity sensors can be 100-500Hz or customized), and have a high protection level, our Lorentzzi brand inductive sensors protection level is IP67.

The disadvantage is that the load capacity of the transistor is not strong and can only be used to detect metal objects. If you need to increase the load capacity, you need to use it with an intermediate relay.

The main difference between inductive and capacitive proximity sensors lies in the types of objects they detect. An inductive proximity sensor detects metallic objects, while a capacitive proximity sensor can detect both metallic and non-metallic objects, such as plastic, fluids, and dust, among others.

For more differences, please refer to this article: Capacitive Vs Inductive Proximity Sensor: 5 Things To Know.

Applications of inductive proximity sensors include object counting, position confirmation, object movement displacement measurement, obstacle avoidance, etc.

Yes, inductive proximity sensors can detect aluminum materials, but the detection distance is usually shorter than iron.

This is because aluminum has a lower magnetic permeability and a higher resistivity, so the eddy currents generated in aluminum are usually smaller than those generated in iron.

According to the output differences, they can be divided into PNP and NPN inductive proximity sensors. The differences? Please learn according to our blog: PNP Vs NPN Proximity Sensors: Key Differences, Wiring Diagram And How To Choose.

According to the working voltage differences, they can be classified into DC or AC type.

If categorized by wire differences, the inductive proximity sensors are AC or DC two wires such as NAMUR sensor, DC three wires(output is NO or NC) and DC four wires types(output is NO+NC).

The two types of proximity sensors have their own advantages and disadvantages.

An inductive sensor can only detect metallic objects. This makes it a good choice in dusty or moist environments, as it will not be affected by dust or moisture. However, the main disadvantage is its relatively short detection distance, which is generally less than that of a photoelectric sensor.

If you want a longer detection distance, you can try using a photoelectric sensor, but the environment must be very clean and the ambient light intensity should be less than 3000 lux.
