Promixty switches also caled proximity sensors. Sensor can devided into inductive type, capactive type, simulative type, Hal l type, magnetic type. Sensor can suppor using of PLC programmable controller, SCM,Sr circuit,Electronic counters, Solid - state relay, Small relays and other products. Capacitive proximity switch are composed by H igh frequency concussion and amplificaton .Sensor detection surface and between the earth form a cpacitor. participated Oscllation circuit work, starting at the stop v bration state. When the object near the surface, the circuit capacity changes, is the Oscillation of highfrequency oscillator. The two states of OscillatorOscillations and stopping vibration, Converted to electrical signals through the shaping amplifer Swith into binary signals. Simulative sensor (also known as the linear displacement sensor), when the metal ovject close to the detection surface.With the change of the distance, then output the singal which have linear relationship changes with the distance, So as to achieve the purpose of monitorng . Hallsensor s a kind of proximity sensor which inside with HalIC.Using Hall effection convert magnetc signal on or off into switch capacity.Widely used n signal detection,automatc control and safety protect on. Magnetic sensor are composed by reed tube and amplfication.When the externa magnetic field near the magnetc reed sensor to force the acton, and then amplif ed by the amplif er,increasing the switching capacity, in order to realize the onoff control of external circuits .
