There are three types of detection systems . Proximity Sensors convert information on the movement or presence of an object into an electrical signal. Proximity sensors are discrete sensors that sense when an object has come near to the sensor face. There are four fundamental types of proximity sensors —the ind— uctive proximity sensor , the capacitive proximity sensor , the ultrasonic prox— imity sensor, and the optical proximity sensor.

An alternating magnetic field is generated in front of these windings.

Composition of an inductive proximity sensor.

The sensors provide excellent even with difficult-to-detect objects, e.

Thus, devices are available with N. 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 . 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. Making Proximity sensing history.

Development of a “dream switch”. As automation spread throughout. Japan, the market demand for high-performance precision switches capable of withstanding more than 1million cycles increased. 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.

They are found in various application domains such as transportation, robots, assembly lines, telecommunication or. Programmable Decision Thresholds sensors. Post-manufacturing configuration and calibration is. Product information - Product Overview for Factory Automation. Inductive proximity sensors provide solid-state reliability for non-contact sensing of the presence or absence of ferrous metallic objects.

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. There are many types, each suited to specific applications and environments. They detect the approach of metal or aluminium targets without contact.

Inductive displacement sensors not only detect the presence of metal objects but also measure distances. This site is operated by KEYENCE CORPORATION. Different principles have been applied to the model that detects metal only and to the model that can also detect non- ferrous .
