Forgestal Bets by the sensor DT35 of Sick

Forgestal Is a Catalan company with international projection devoted to the manufacture of machinery for the sectors of ceramics and metal. Roger Noguera, technical manager of the company, explains why in Forgestal bet by the sensors of Sick: “In Forgestal apply sensors Sick DT35 connected to the PLC by means of IO-Link to control the position of the axles of our machines. A typical machine uses five sensors of this type to control other so many axles.”

The environingingment of work is relatively last for the cell, dry but with quite a lot of dust. The company has not experienced problems of failure by ensuciamiento in his rank of apli-cación (until 10 metres).

“The advantages that obtain with regard to the previous systems are multiple”, continuous Noguera. “The sensor DT35 does not have delicate mobile parts and does not be necessary to do one ranges-ción accurate as it requires an encoder. We obtain an absolute position, that natural-mind conserves after a cut of current. It is more, we can substitute a sensor damaged and the position also conserves , without need to realizar a put to zero”.

The parameters of the sensor remain stored together with the program of the PLC and does not be necessary to remember complicated sequences of keys on the cell to set up it. The works of maintenance remain very simplified. The interface IO-Link allows to use conventional cables with connector M12. Like this it avoids the use of cables apantallados, that require special connectors and a more delicate setting.

“The delay of the signal that arrives to the PLC is smaller compared with the cards of in-trada 4-20mA conventional that used in the past. In definite, when the preci-sión and speed are sufficient for the application, the DT35 is an excellent election”, concludes Roger Noguera.
