Safety Explosion-proof Proximity Switch

      Namur sensor, also called safety explosion proof proximity switch, is made according to NAMUR and DIN 1923, measured and designed as per chemical industry standard.

      With low-voltage power supply,micro-current output,small volume and other advantages.Namur sensors can be applied for special places with requirements of explosion proof.

Working priciple inductive proximity switch
 
      Inductive proximity switch is composed of three parts:oscillator,switch circuit and magnified output circuit.The oscillator will generate an alternating electric field.When hemetal object approaches this electric field and reaches the induction distance, whirlpool will generate in metal object, resulting in attenuation of vibrati on and then stop.The changeof vibration and stop of oscillator is treated by begid stage magnified circuit and convertedto switching sign,triggering driving con-contact detection.
     Current consumption of inductive proximity switch decreases proportional to the metal object distance.
