Working of proximity sensor pdf

Because of this operating principle, inductive proximity sensors are only used for sensing metal objects. They will not work with non-metallic materials. Solid state technology : no moving parts, therefore service life of sensor independent of the number of operating cycles.

For inductive proximity sensors sold to the Original User for the lifetime of the original application.

The following terms apply to the LIFETIME. A magnetic field sensor is suitable for objects capable of car- rying magnets. Additional information on the functions of these proximity switches can be found at the beginning of the respective sec- tions. Principle of high-frequency oscillation type inductive proximity sensor.

When an object (metallic) approaches this magnetic fiel induced currents flow in the metal, causing thermal loss and . Capacitive proximity sensors are similar to inductive proximity sensors. The main difference between the two types is that capacitive proximity sensors produce an electrostatic field instead of an electromagnetic field. Whether metal or other solid materials such as wood or pa- per, liquids, granules or permanent magnets, the solution for your application is within reach with the proximity sensors from SICK. EMC, supply voltage available, load type , etc.

Select the sensor by referring to the size and type of material to be detected. Check the minimum distances between sensor and damping materials or another sensor. Check that the number of operations does not exceed the maximum switching frequency. Typically used for intrinsically safe applications. An enclosure rating per NEMA Standard 250.

There are many types, each suited to specific applications and environments. Output reverse polarity protection, . C 2-wire NAMUR Intrinsically Safe, Cable Style Tubular Sensors. Nickel-plated Brass Barrel, Plastic Face. Navigation in the PdF document.
