What are Inductive Sensors?
Inductive proximity sensors function so that ferrous metals in the proximity of the active surface (sensing area) will produce oscillations that lead to a change of state. Unlike a capacitive proximity sensor that oscillates when the target is present, an inductive proximity sensor oscillates until the target is present.

By applying a voltage to the oscillator coil, an alternating inductive field is created in front of the active surface (sensing area) of the unit. When a metallic object (e.g. steel, aluminum, copper, brass etc.) enters the sensing field from any direction, it causes the state of the oscillator to be modified until the threshold trigger is inverted. This induces a change in the condition of the final stage and the consequent command of an external load.

In inductive ring sensors, sensing is made within the ring itself. The sensor is activated when a metallic object is introduced within it. When choosing an inductive ring sensor, select a size based on the minimum hole diameter required.

How are Inductive Sensors Used

How are Inductive Sensors Used?
Inductive sensors have wide uses in many applications, some of which involve difficult working conditions that may use oils, powders, liquids, and vibrations that do not have any effect on the sensors’ secure functioning. AECO’s inductive proximity sensors can also be used in the automobile industry and in all applications where solutions for automation are required. Aeco’s inductive proximity ring sensors are particularly advantageous for:

  • Detection of small metal objects (e.g. screws, nuts, washers etc...)
  • Detection of breaks in continuous metal wires that pass through it

Things to Consider When Choosing an Inductive Sensor

Things to Consider
When Choosing an Inductive Sensor

When selecting an inductive proximity sensor, it is suggested to take into consideration:

  • Sensing distance
  • Housing (shielded or unshielded)
  • Output type
  • Material (plastic or metal)
  • Shape (cylindrical or rectangular)

The sensing distance depends on the type of metal and the thickness of the material. The main advantages offered by proximity sensors in relation to normal limit switches are:

  • Mainly unlimited duration since they have no moving parts (wheels, springs etc...)
  • Lack of maintenance required
  • Elimination of possible false contacts from contact movement
