Inductive Proximity Sensors

Features :
  • For sensing metal targets
  • Non-contact sensing
  • Solid state circuitry
  • Durable in aggressive environments
  • Wide Variety in Extended Sensing Range
  • Available in all voltage Range ( AC / DC / AC, DC )

 

Capacitive Proximity Sensors

Features :
  • Detects non-metal objects
  • Address more applications
  • Not color-dependent
  • Less surface-dependent
  • Very small “blind zone”
  • Lower cost to customer than ultrasonic
  • Available in all voltage Range ( AC / DC / AC, DC )

 

Limit Switches

Features :
  • Electromechanical Device
  • Requires Contact with target object
  • Can handle heavy loads
  • No leakage current or voltage drop
  • EMI/RFI Immune
  • Availble in all standards

 

PhotoElectric Sensors

Features :
  • Strengths over other sensor technologies
  • Does not depend on target material
  • Extended distances to 200m or more
  • Fast response times to 30ms
  • Available in rectangular , cylindrical shapes
  • Available in all voltage Range ( AC / DC / AC, DC )
  • IP 67 Protection

 

INCREMENTAL ENCODER

Features :
  • 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

ABSOLUTE ENCODER

Features :
  • 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

Ultra Sonic Sensors

Features :
  • 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
