Reed Sensor

 

Reed sensor also called magnetic switch, reed sensor is application for position determination of pneumatic and / or hydraulic cylinder and piston pump. It also can be used as limit switch .When the magnetic object approaches, the reed closes and sends out switch signal through magnification. Compared with inductive sensor ,it has the following strong points: can be installed in metal closely and side by side and detect through metal object.Its detection distance subjects to the intensity of magnetic field of detected object.Reed sensor is not applicable in the occasion of severe vibration.

 

Features:

 

1 . Diversified exterior structures 
2 . Good performance of anti-interference. 
3 . Many output forms 
4 . Dust proof,vibration proof,water proof and oil proof. 

5 . With short-circuit protection and inverted connecting protection.

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.
