Key position

Proximity switches are key products in auto-mation systems. Thousands of them are usedin factories in the automobile industry and inmachine construction, e.g. for the area ofpackaging machines, machines for the foodand beverage industry.

An overview of the mostimportant features

The wireless proximity switches provide thesame basic functions as conventional inductiveproximity switches. However, they do notrequire any cable connections for the powersupply and data transfer between sensors andmachine control system. This opens up com-pletely new possibilities for the construction ofmanufacturing machines. Particularly the highcosts for wiring to connect a high number ofsensors with the machine control system canthus be avoided. Furthermore, the reliability,safety and availability of a production systemare considerably improved. The continuouspresence check of each wireless sensor enablesearly fault detection and the time-consumingsearch for faulty cables is no longer necessary.

The assortment ...

... consists of 4 flush-mounting and 4 non-flush-mounting, wireless inductive proximity switches.Depending on the size M8, M12, M18 and M30,nominal switching distances Sn can be achievedbetween 1.5 mm and 15 mm.

Design

The wireless proximity switches consist of twoparts: the sensor head and the communicationmodule which is identical for all sensors. Themodule obtains the required energy for thesensor function and the radio communicationfrom an electromagnetic field.

Communication ...

... takes place in the 2.4 GHz band according to the stan-dard ETS 300328 and uses a frequency jumping process forreliable data transfer. The input module, which up to 120 wire-less proximity switches are allocated to, communicates thesensor signals via two antennas and transmits these to themachine control system via a FieldBusPlug (FBP).A maximum of 3 input modules and with these up to 360wireless proximity switches can be used in one machine cell.A continuous function messaging of the sensors every 500ms ensures maximum reliability and immediate detectionof failures.

Energy transfer

The electromagnetic field used for transfer of power is pro-duced by a power supply via primary loops. The individualpower loop has a dimension of 1 m x 1 m to 3 m x 6 m. Thisresults in a supplied volume of 1 m x 1 m x 1m to 3 m x 3 mx 6 m.

Advantages ...

... of the wireless proximity switches:> considerably reduced engineering costs> short commissioning times> high reliability and availability of the production system> high level of safety due to continuous presence check
