Presents new inductive proximity sensors

Turck presents new proximity sensors with extremely large switching distance and magnetic field immunity making their use safer and more accurate.

Inductive proximity sensors serve for wear-free and non-contact detection of metal objects. They operate with a high frequency electro-magnetic AC field which interacts with the target. With conventional sensors, this field is generated by a LC-resonance circuit with a ferrite core coil. Uprox inductive sensors operate on a new detection principle. In addition, due to their ferrite-less 3-coil construction, they incorporate features which provide them with significant advantages for a wide range of applications compared to conventional inductive sensors.

The new uprox ® generation combines the features of our proven uprox ® sensors with quite new characteristics, making their application even more simple and safe:

• extremely large switching distances

• integrated pre-damping

• protection through self-compensation

• excellent electromagnetic

capability according to EN 61000-4-6 (future standard for proximity switches from 2005 on) In addition to the known and well established properties of inductive uprox ® sensors, such as

• factor 1 for all metals

• magnetic field immunity

• high switching frequency

• large temperature range

the new generation offers these novel and exceptional features without accepting the common disadvantages associated with sensors with large switching distances. The most significant drawback of sensors with extremely large switching distances, i.e., the difficult and hardly practicable mounting procedure, has been completely eliminated.
With TURCK sensors, flush mounting is what you expect: a really fully embeddable design. This is also true for the uprox ® types with extremely large switching distances, such as the CK40 (40 x 40 mm) with a nominal switching distance of 30 mm.

That’s a world record! Take full advantage of the sophisticated performance of the entire sensor series - you won’t have to make any concessions. The novel pre-damping protection allows partial embedding of most non-flush sensor types in metal. This is made possible by the self-compensation feature of the pre-damping protection, ensuring constant availability of the maximum switching distance. 

Mounting errors are eliminated, thus enhancing system availability, facilitating system construction and reducing sensor inventories. The switching distance variations always remain within tolera-ble limits as opposed to conventional inductive sensors, which are pre-damped when partially embedded in metal and are then liable to deliver faulty signals (e.g. due to temperature drift). 

With the new uprox ® series, reliable operation is ensured, even when all other features are used (e.g. the full temperature range). With these sensors you will always be on the safe side - without having to make any compromises on effectiveness. In other words: top performance in all applications.
