Inductive proximity switches are sensors capable of detecting the presence of objects in the immediate proximity of its sensitive side without physical contact.Let’s find out their characteristics together and why choose them!
Which are their main characteristics?
- A high resistance to electrical and electromagnetic disturbances
- A considerable mechanical strength
- A wide range of versions with different functions
- Customizable houses and different way of connections
How do inductive proximity switches work?
The inductive sensors contain a transistor oscillator whose power consumption is influenced by the approach of metals and other electrically conductive materials. This effect can also be achieved through a non-conductive material. Depending on the type, the current change of the oscillator will be amplified to a streamlined output signal or output as a binary signal by a switching amplifier.
The proximity sensors can be used in machines, systems and vehicles as limit switches, contactless position switches for monitoring and positioning, as pulse generators for counting tasks, distance and speed measurements, and for many other applications.
Why choose proximity sensors?
Inductive proximity sensors are applied on hydraulic cylinders, pistons, translating shafts, control levers, in particular on machine tools, agricultural and industrial vehicles and machines intended for the textile and automotive industry. These sensors are also used to detect metal objects in harsh environments, as well as to control the passage of objects that follow one another at a high speed. Furthermore, inductive sensors represent the most economical and technically correct solution for safe detection up to a distance of 10 mm in 99% of cases.
