About Pneumatic Air Cylinder Magnetic Reed Switch

Introduction to proximity switch: Integrated circuit proximity switch, also known as non-contact proximity switch, it is composed of an oscillator and shaper amplifier oscillator up, so that the oscillation amplitude is weakened so that the shutdown makes the proximity switch reach the month of reversal, P by shaper into binary switch electrical signals, so as to achieve the purpose of detection. This approach switch series is designed for high frequency mode, it with no contact, no pressure, no spark, signal detection, fast to drive the relay or logic gates, it has high sensitivity, fast frequency response, high repeat positioning accuracy, shun variable process short, big output power, anti-jamming performance is good, work stability, reliable, long life and other advantages, switch inside filled with resin, fully enclosed, vibration resistance, corrosion resistance and waterproof, etc. Working principle: The proximity switch consists of three parts: the oscillator, the switching circuit, and the amplifying output circuit. The oscillator generates an alternating magnetic field. When the metal target is close to the magnetic field and reaches the induction distance, eddy currents will be generated in the metal target, which will lead to attenuation of oscillation and even vibration stopping. The changes of oscillator oscillation and shutdown are processed by the rear stage amplifier circuit and converted into switch signals to trigger the driving control device, so as to achieve the non-contact detection of the self-labeling sensor, the closer the target is to the sensor, the greater the damping in the coil; The greater the damping, the smaller the current in the sensor oscillator. The current loss of inductance proximity switch decreases with the decrease of the distance from the metal target. Package list: 1 x Magnetic Reed Switch
