Sonar Proximity Switches SIMATIC PXS
From 2,5 cm to 10 m - They Hear Everything!
Our sonar proximity switches sense objects of varying materials, shapes, colors or consistencies with absolute precision, flexibility and reliability. The application potential is almost unlimited. Whether recording fill levels or heights, measuring distances or counting bottles, our switches recognize objects with a wide range of properties from a distance of 2,5 cm to 10 m, regardless whether they are liquid, solid, powdery or even transparent. Surface conditions are irrelevant as well - they can be rough or smooth, clean or dirty, wet or dry. Our proximity switches feature maximum ruggedness and resistance against dirt, vibration and extraneous light or sound.

Capacitive Proximity Switches SIMATIC PXC
Monitoring Fill Levels and More
Capacitive proximity switches also operate contactless and equally respond almost instinctively when conductive or non- conductive materials in solid, powdery or liquid states have to be measured. They are particularly convincing in monitoring fill levels through non-metallic materials such as plastic or glass, and in counting objects made of various substances.
|
|
|
Proxistor capacitives produce an electric field with which they detect electrically conducting or non-conducting materials, solids particles or liquids, without making contact. Target detection is not affected by colour. Almost all Proxistor capacitives feature adjustable sensitivity allowing them to be set-up to differentiate between materials or compensate for varying mounting conditions.
|
|
Capacitive proximity sensors react to metals and non-metals that exceed a specific capacitance on approaching the active surface.
The sensing distance with resprect to a specific material is greater the higher the dielectric constant.
The sensors are used to detect objects, for counting functions and for all types of level monitoring applications (liquids and solid materials.
|
|
|
Capacitive proximity switches are designed for non-contact and wear-free detection of metal (electrically conductive) and non-metal (electrically non-conductive) objects.

In all automated processes the use of sensors to provide information for the plc is of prime importance. Sensors supply the necessary signals on positions, end stops, levels or serve as pulse transmitters for counting jobs or for monitoring rotational speed. In industrial usage inductive and capacitive proximity switches are indispensable. As compared to mechanical switches they offer almost ideal conditions: non-contact, maintenance-free operation, high switching frequencies and switching accuracies as well as high protection against vibration, dust and humidity.
Inductive sensors detect all metals without contact, capacitive sensors detect nearly all solid and liquid media such as metal, glass, wood, plastic, water, oil, etc...
Both inductive and capacitive proximity switches are available in NAMUR versions. In conjunction with an NV0100/NV0200 amplifier the sensors can be used in zone 1 hazardous areas (the amplifier which contains Zener barriers as well as power supply and output must be mounted outside the hazardous area).

The capacitive sensors with extreme long sensing distance are based on the three-electrode measuring-principle. this measuring principle allows much larger sensing distances compared to the two-electrode principle of common capacitive sensors, up to 10-times the norm. Although one achieves essentially larger switching distances with these capacitive systems, the size of the sensors is small.
KXS-Systems are used for applications where the sensing distances of standard sensors are not sufficient.
A further feature is the Duplex-or Triplex-operation. With the corresponding evaluation unit it is possible to adjust 1, 2 or 3 switching points with only one sensor.

Capacitive sensors (KAS) react to metals and non-metals that exceed a specific capacitance on approaching the active surface. The sensing distance with respect to a specific material is greater the higher the dielectric constant. The sensors are used to detect objects, for counting functions and for all types of level monitoring applications in liquid materials (i.e. water, oil, acids, glue) and bulk materials (i.e. pouder, granulate, pellets).

Inductive Proximity Switches SIMATIC PXI
Instinctive Response to Metal
When identifying metal objects without contact, inductive proximity switches are simply the most cost-effective solution. If an electrically or magnetically conductive object approaches or leaves, they automatically send out a signal change. Inductive proximity switches are extremely reliable with a high repeat accuracy. And thanks to wear-free operation as well as resistance to temperature, noise, light or water, they have a markedly long service life. We cover the complete application spectrum with a large variety of designs and transmission ranges.

Inductive proxistor's detect the presence of ferrous or non-ferrous metals without making contact and offer metal sensing unaffected by dirt, oil humidity & dust. This makes them particularly suitable for use in both the machine tool and general manufacturing environments where they are present in great volume and variety.
|
|
Inductive sensors (IAS) feature transistorised oscillators whose power consumption is influenced by the approach of metals and other electrically conductive materials such as carbon. Non-conductive metals can also achieve this effect.
These devices can be used as limit switches and position sensors for monitoring and positioning applica-tions in machines and installations as well as pulse generators for counter systems, distance measurements, speed control and many other applications

Position and movement detection is indispensable in the automation industry. Non-contact proximity switches allow for a significantly higher number of switch operations than mechanically operated switching elements. The different elobau variants usually use reed technology and are operated with magnets. Steel proximity switches and vane switches are the exception as they are operated by a ferrous metal.

BNS range magnetic safety sensors serve to monitor the position of sliding, hinged and removable safety guards. Sensors without integral evaluation can only be used for safety duties to DIN VDE 0660-209 in combination with a safety guard monitor of the AES / AZR range for protection up to Control Category 4 to EN 954-1, see chapter 10.2.
The use of magnetic safety sensors is of particular advantage in cases where extremely dirty conditions can occur or high hygienic standards need to be maintained. This is provided by the simplicity of cleaning the units.
A further advantage is the facility for concealed mounting under non-magnetic materials. Working surfaces and storage areas can be arranged without the need for dust-collecting edges or other functionally required cut-outs or projections.
BNS range magnetic safety sensors can also be used in cases where a precise approach is not possible and greater tolerances are required.
Schmersal make both standard and AS-i Safety at Work magnetic safety sensors.

Ultrasonic sensors use ultrasonic waves for non-contact and wear-free detection of a large variety of objects. It does not matter whether the object is transparent or opaque, metallic or non-metallic, or of liquid, solid or powdery consistence. Environmental conditions such as spray, dust or rain hardly affect their function.

Capacitive sensors evaluate the change in capacitance which occurs when an object enters the electrical field of a capacitor. When appropriately dimensioned, the capacitive sensor is also able to “see through” certain non-metallic materials. This ability makes it the classical level detector, sensing the level of liquids and granular products through container walls..

Capacitive Sensors
Like inductive sensors, capacitive sensors function without physical contact with the target material. Capacitive sensors allow for the detection of both, conductive and non-conductive materials, but are most commonly used for sensing materials such as plastics, liquids, powders and granular materials.
In applications utilizing capacitive technology the sensitivity of capacitive proximity switches is dependent on the material characteristics of the target object. This material characteristic of the metal, plastic or liquid object will influence the sensing range and therefore the output detection point of the capacitive sensor. To allow for this variation in material characteristics Pepperl+Fuchs offers many models with adjustable sensitivity to allow for more flexibility in applying these sensors to your application.
These capacitive sensor products offer an alternative technology for use in applications where the use of inductive sensors may not be possible.
