Inductive Encoder Eliminates Need for Compromises

Turck’s new encoder means that the user no longer has to make a

compromise between resolution and rugged design. All the mea-

sures required to protect encoders from mechanical stress using

springs or double bearings are no longer necessary. Apart from

the interference immunity and wear-free design of the system,

the user also benefits from the universal parametrization concept.

The mounting concept also keeps this universal approach: Adapter

rings make it possible for the user to fit the positioning element to

shafts of different diameters. He only has to keep a single encoder

in stock which he can use for all applications on shafts up to 20

mm in diameter. Our customers are thus able to reduce their stor-

age costs effectively.

The QR24 universal encoder can be used for a countless number of

applications and replace several 100 different encoder types.

The resonant circuit measuring principle makes it possible to

design a fully potted sensor housing without seals, that is separate

from the positioning element. This therefore fully excludes the

possibility of dust or water penetrating into the electronics.

The contactless measuring principle of the encoder enables it to

compensate for vibration and offset.

Magnetic fields cannot disturb the measuring process, since the

positioning element is not based on a magnet but on an inductive

coil system, through which the sensor and the positioning element

(resonator) can form an oscillation circuit.
