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.
SensoPart offers a variety of inductive sensors with standard or enhanced working ranges.

Proximity sensors are the most common and affordable solution for no-touch object detection. The most commonly-used proximity sensor is the inductive type, which generates an electromagnetic field to sense metal objects passing close to its face. This is usually the easiest sensing technology to apply in applications where the metal object to be detected is within an inch or two of the sensor face. Autonics offers 12 products of 6 different types of proximity sensors, inductive and capacitive, and maintains No. 1 market share in Korea for more than 10 years, and still endeavoring to advance product quality and sensing reliability up to the top level of global marketplace. If you are looking for the most cost effective and reliable proximity sensors, Autonics is the answer.

Different object colours and surfaces can heavily effect the detection behaviour of an energetic switch. With purely energetic evaluation, it is, for example, not possible to detect a black object in front of a white background.The white background reflects more light than the object itself.
In order to deal with such applications reliably, the background suppression procedure was developed. In this procedure, both the light reflected by the background and by the object is evaluated.The light is captured by two different receiver elements. With this procedure, it is possible to reliably detect e.g. a dark object on a light color conveyor belt.
There are two different procedures for the physical realisation of background suppression. In general, a distinction is made between a fixed and adjustable background suppression. With a fixed background suppression, the transmitter and receiver elements are rigidly mounted.
The laser units are particularly suitable for the detection of very small objects. With larger objects, a red-light or infrared sensor should be used. Only the background suppression procedure enables the detection of a dark object on a light conveyor belt.

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.

Honeywell environment sealed proximity sensors use a variety of technologies, including Eddy Current Killed Oscillator (ECKO) and Hall-effect, which are used to detect metallic objects passing in front of the sensing face. Once a target metal is detected, a trigger signal is produced and passed through the output conditioning circuitry to give an output that can be configured according to the sensor's application. These rugged, one or two-piece products meet demanding requirements such as temperature, vibration, shock and EMI/EMP interference. They are available in a variety of housing materials and termination styles, and meet military standards.
Best Used For:
Harsh environments such as aerospace, ordnance and marine applications.

Capacitive proximity sensors are ideal for sensing non-metal objects or for level control of fluids and granular material.
Adjustment can be used to zero out the presence of an object allowing the sensor to sense "through" a bulk material or liquid level.
The operating distance of a capacitive sensor is related to the dielectric constant (εr) of the object material to be detected. The higher the value of εr, the easier the detection of the object will be. The object to be detected through must have a lower εr value.
The threshold level is adjustable via a 20-turn potentiometer located at the rear of the sensor

Level and feed monitoring - that is one of the attributes of capacitive sensors. Irrespective of whether it involves a solid material such as paper or wood, granules or liquids. They reliably detect the status of the product in the production process and during final inspection.
Capacitive sensors supplied by SICK are always convenient to use. Sensing ranges between 1 and 25 mm allow clearance in almost any installation situation and they are extremely adaptable for a wide range of applications.
Thereby these sensors are suitable for extremely adverse industrial environments. Impurities and contamination, dust and airborne spray particles have little effect upon them as does electro-magnetic interference. No wonder that they are installed in the most diverse branches of industry. In the food industry, car industry or in storage and conveying technology.
