  22. Inductive proximity switch Inductive Proximity switch produces high frequency alternating field at the sensing face. When any metallic material enters in the sensing zone of the switch, the field gets disturbed. A Sensitive detector circuit senses this change which is further processed by amplifier circuit to produce output signal.

  32.            <title>Capacitive Proximity Switches</title>
  33.            <description>When the object enters in the sensing zone of the switch, capacitance between two plates of capacitor (one plate is represented by electrode at sensing .face of the switch and another by all surrounding material which is connected to the earth) changes. As soon as capacitance value crosses preset level, oscillator starts. This change is detected and resulted in an output signal.</description>

  42. The magnetic switch senses presence of magnet and give specified signal.
  43. Magnetic switches are of two types :
  44.  
  45.    1. Reed Type
  46.    2. Solid state, Hall effect type</description>

  53.            <description>Beam of invisible pulsed modulated infra-red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by received placed near emitter (in diffuse version). When this beam is interrupted by object, the receiver signal gets changed and signal is produced.
  54.  
  55. Optical proximity switches are used where higher sensing distance is required with non contact operation.
  56.  
  57. The object can be sensed by three methods
  58.  
  59.    1. Diffused Reflective Type
  60.    2.  Retro Reflective Type
  61.    3. Through Beam Type
