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 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 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.

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.

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.

PSEN sensor technology, Safety for man and machine
Safety switches ... for safety gate and position monitoring :
Hazardous machine movements must be stopped when a guard is opened. It must not be possible to either defeat or manipulate these guards. PSEN safety switches meet this requirement and are therefore suitable for monitoring gates in safety fences for safety zones, for example.
Safety bolt ... for safety gates in a rugged everyday industrial environment :
For safety gates that are difficult to adjust or in areas where safety gates are often opened and closed, protection must be provided against defeat and manipulation, but a long material service life must also be guaranteed. PSENbolt provides a complete solution, comprising safety switch, handle and bolt.
Safe camera systems : to monitor two-dimensional (2D) or three-dimensional (3D) zones.

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.

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.

Capacitive sensors
The non-contact capacitive sensor transforms a dimension important for production technology (distance or fill level) into a signal for further evaluation. It functions on the basis of the modification of the electrical field surrounding its active zone. The basic structure of the sensor consists of a RC oscillator as sensor, a demodulator and an amplifier. Metals or non-metals which come close to the active zone of the capacitive sensor cause a capacity change, so that the RC oscillator begins to oscillate. As a result, the trigger downstream from the oscillator switches and the signal amplifier alters its output status. Depending on the type of device, the switching function at the output can be N.C, N.O or a change-over contact.
Applications
The capacitive proximity switches are suitable for the control and monitoring of machine processes and as signal transmitters for counting tasks, which involve metals and non-metals; for signalling levels in containers and through container walls, where liquid, powdered or grained substances are to be detected.
