Inductive sensors | Proximity sensor

An inductive sensor or inductive proximity sensor works according to the principle of change of impedance / inductance. When the proximity sensor comes close to a metal object, the inductance / impedance changes in the coil. This change in inductance or impedance depends on the distance between the metal object and the sensor. The inductive sensor or inductive proximity sensor is ideal for detecting ferrous metals (alloys where iron is the main ingredient) at a short detection distance and is not affected by non-conductive materials such as wood and plastic.

Proximity sensor

Proximity sensors are not optical sensors, but react to metal objects using magnetic fields. Proximity sensors are implemented in concise and non-concise sensors. Proximity switches are insensitive to dust, sunlight, dirt and reflections. An inductive sensor is often used in harsh conditions with short switching distances and metal objects.

In addition to the materials to be detected, the following factors are important for the choice of a sensor type:

  • Switching distance
  • Installation type: concise / non-concise
  • Construction: cylindrical / rectangular
  • Connection: connector / cable
  • Output type: PNP / NPN
