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.

The reed switch is an electrical switch operated by an applied magnetic field. It was invented at Bell Telephone Laboratories in 1936 by W. B. Elwood. It consists of a pair of contacts on ferrous metal reeds in a hermetically sealed glass envelope. The contacts may be normally open, closing when a magnetic field is present, or normally closed and opening when a magnetic field is applied.
A magnetic field (such as from an energized coil around the glass tube or a permanent magnet moved towards it) will cause the contacts to pull together, thus completing an electrical circuit. The stiffness of the reeds causes them to separate, and open the circuit, upon removal of the magnetic field. A more complicated configuration contains a nonferrous normally closed contact that opens when the ferrous normally open contact closes. Good electrical contact is assured by plating a thin layer of precious metal over the flat contact portions of the reeds.

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).

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.

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.

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.

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.

Inductive sensors
Inductive sensors use the interaction between metallic conductors and their electromagnetic alternating field. Eddy currents are induced in the conductor, which remove energy from the field and thus reduce the height of the oscillation amplitude.
This change is evaluated by the inductive sensor.
