The WK2 system is especially suited for tool monitoring in the most challenging machining environments.


Characteristics:

  - Absolutely leak proof in the most demanding environment
  - Fast and constant scanning speed
  - Sensor diameter only 22mm
  - Scanning direction right or left
  - Object, tool, and free space scanning
  - PNP outputs, wear resistant, short protected
  - NPN outputs, wear resistant, short protected
    (with WK2S controller only)
  - Inverting of outputs via DIP switch
    (with WK2S controller only)
  - Output latching until new scanning cycle
    (with WK2S controller only)

Features:

  - Triple sealed
  - The V-seal eliminates reliably any deposit between moving parts
    dried up coolant during production standstill does not create malfunctions
  - The chromium-plated special steel housing is wear resistant against shavings and chemicals
  - Wear resisting probe end made of carbide
  - Positioning, speed, and torque controlled drive offers a soft contact at the tool
  - No external mechanical stop
