Proximity switch is a type of switch type sensor (i.e. contactless travel switch) that has the characteristics of travel switch and micro switch, as well as the performance of sensors. It has reliable action, stable performance, frequency response, long service life, strong ability, waterproof, shockproof, corrosion-resistant, and other characteristics. It is widely used in industries such as machine tools, metallurgy, light textiles, and printing. In automatic control systems, it can be used as a limiting, counting, positioning control, and automatic protection link. Proximity switch LN21R magnetic switch proximity switch working principle proximity switch consists of three main parts: oscillator, switch circuit, and amplifier output circuit. The oscillator generates an alternating magnetic field. When the metal target approaches this magnetic field and reaches the induction distance, eddy currents are generated within the metal target, causing oscillation attenuation until it stops. The oscillation and stop changes of the oscillator are processed by the subsequent amplification circuit and converted into switch signals, triggering the driving component to achieve non-contact detection. Proximity switch, also known as contactless proximity switch, is an electronic switch quantity sensor. When the metal detection body approaches the sensing area of the switch, the switch can quickly issue electrical commands without contact, pressure, sparks, and accurately reflect the position and travel of the moving mechanism. Even when used for general travel control, its positioning, operating frequency, service life, convenience of installation adjustment, and adaptability to harsh environments are incomparable to general mechanical travel switches. Magnetic proximity switches are domestically produced products that fundamentally solve the impact caused by any electric field interference due to the use of magnetic induction principle. This series of switches has a long operating distance, strong performance, good sealing performance, stable and reliable magnetic force, and a hemispherical working characteristic. It has the characteristics of easy installation, long service life, and can work in high temperature, temperature, and harsh environments. They are widely used as position control switches in steel rolling, coking, shipbuilding, mining, lifting, transportation, and other fields, or replace the original slide contactor mechanical limit switches. They are domestically produced products and components that achieve contactless transmission of control signals.
