• Output provides relative position of the shaft –external electronics such as
  
• Use when retention of position data is not required when power is lost
  
• counters are required to accumulate data to determine position ,speed
  &direction
  
  
• Used for speed or relative position :

Velocity Control
Point to Point
Sequencing

• Output provides the absolute angle position of the shaft Use when position data must be retained on loss of power
  
  
• Used for position control for :

Packaging Machines
Robotics
Lead / Ball Screw
Rotary Table Positioning

• No Touch Detection:

Presence
Distance
Level
Diameter

• Not affected by the following:

Color
Light
Dust
Mist

• Transducer / Receiver :

Sends Sound Waves
Receives

• Comparator & Detector Circuit :

Calculates “ Times of light ” to determine distance

• Solids State Output Switching Device :

Sends the output to be interpreted by an interface
Discrete – Presence / Absence of a Target
Analog – Distance to an Object
