Proximity switch also called proximity sensors . Sensor can devided into inductive type , capacitive type , simulative type , hall type, magnetic type . Sensor can support using of PLC programmable controller ,SMC , Sr circuit ,Electronic counters, Solid-state relay ,Small relays and other products .
Capacitive proximity switch are composed by High frequency concussion and amplification. Sensor detection surface and between the earth from a capacitor participate Oscillation circuit work , starting at the stop vibration state . When the object near the surface , the Circuit capacity changes , is the Oscillation of high-frequency oscillator . The two states of Oscillator-Oscillations and stopping vibration , Converted to electrical signals through the shaping amplifier switch into binary signals .
Simulative sensor (also known as the linear displacement sensor ),when the metal object close to the detection surface . With the change of the distance , then output the signal which have linear relationship changes with the distance ,So as to achieve the purpose of monitoring .
Hall sensor is kind of proximity sensor which inside with Hall IC.Using Hall effection convert magnetic signal on or off into switch capacity . Widely used in signal detection , automatic control and safety protection .
Magnetic sensor are composed by reed tube and amplification. When the external magnetic field near the magnetic reed sensor to force the action , and then amplified by the amplifier , increasing the switching capacity , in order to realize the on-off control of external circuits .
