counting, measurement or monitoring

SIMATIC PX proximity switches for reliable

sensing, counting, measurement or monitoring

Whether the objects are in solid, liquid or powder form;

whether you want to detect, count, measure, monitor or posi-

tion: Proximity switches are invaluable in plants of all types

and sizes; in conveyor systems, packaging lines or printing

presses, and in production robots, lifts, industrial presses or

automatic welders.

Comprehensive automation, complex operational sequences

and high work speeds pose exceptional demands which are

met by the broad range of proximity switches:

Portfolio overview

Totally integrated in TIA

IQ-Link is a concept for the intelligent integration of sensors in

automation systems. Just like all products and systems incor-

porated in Totally Integrated Automation, IQ-Link devices also

feature the same properties with respect to communications

capability, data management and configuration/program-

ming. This provides advantages in every aspect, and not just

enormous savings potential for engineering. For the first time,

plant-wide communication down to the sensor level can be

implemented not just extremely easily, but highly profitably as

well.

SIMATIC PXS sonar proximity switches

Sonar proximity switches can be used as non-contact proxim-

ity switches in many fields of automation.

These devices can be used whenever distances through air

have to be evaluated, because they not only detect objects,

but can also output and evaluate the absolute distance

between the Sonar proximity switch and the object. Changing

environmental conditions (e.g. temperature variations) are

compensated during evaluation of the measurement.

SIMATIC PXO optical proximity switches

The photoelectric proximity switches react to changes in the

received quantity of light. The light beam emitted from the

emitter diode is interrupted or reflected by the object to be

detected.

Depending on the type of BERO, the interruption or reflection

of the light beam is evaluated.

SIMATIC PXI inductive proximity switches

Inductive proximity switches are the low-cost solution for

non-contact detection of metal objects.

Inductive proximity switches are extremely reliable with a

very high repeat accuracy and long service life thanks to no-

wear operation as well as their insensitivity to temperature,

noise, light and water.

SIMATIC PXC capacitive proximity switches

Capacitive proximity switches are also non-contact sensors for

measuring conducting and non-conducting materials in solid,

powder or liquid state.

Intelligent proximity switches

Easy to insert, simply more productive

Sensors and PLCs are growing together

Sensors are becoming more intelligent and versatile. Thus set-

ting and evaluation possibilities are increasing.

Thanks to intelligent linking to the PLC, IQ-Link can now be

used to implement significantly more flexibility and reliability

of the sensors.

The uniform exchange of data presents a great number of ad-

vantages - for plant construction as well as for its operation.

Thanks to the integrated availability of parameters, for exam-

ple, a setting made on a sensor can be transferred to other

sensors as often as required.

Central data management ensures that the sensors continue

to work with the correct setting values without new parame-

terizing even after replacement.

Furthermore, IQ-Link permits channel-specific system diag-

nostics. In addition to failures in wiring sensor-specific errors

will be detected.

Thanks to TIA all these augmented functions are available in

the usual system environment without additional configuring.

TIA provides this already system integrated.

New communication standard:

IO-Link

Well-known manufacturers of sensor and automation technol-

ogies partnered up under the roof of the PROFIBUS user orga-

nization (PNO) to develop an integrated communication stan-

dard for sensors and actuators. After completion of the

specification at the beginning of 2008 together with the inte-

gration into the fieldbus level first IO-Link products will come

into the market.

Retaining the low-priced point-to-point wiring the goal was to

create potential for further cost reductions for the user on

commissioning and maintenance costs as well as plant avail-

ability.

The proven IQ-Sense technology from Siemens was incorpo-

rated into the IO-Link specification. Siemens has played and

will play a leading role in the creation of the new standard

which additionally has been turned in as an IEC standard.
