SPEED DETECTOR　KPS Series  
Surely detects the speed change of the conveyor!
Prevents parts and motors from being damaged.
  • High precision detection is achieved by using a digital control method.
  • The operating speed can be set freely with the range of 3 to 1999 rpm.
  • The built-in startup compensation timer makes it possible to set up the startup compensation of 99 seconds at the maximum.
  • Use of a proximity sensor for the sensing unit makes the detector contact-free and eliminate moving parts, which results in the long life duration.
    (KPS-21)
  • As the conveyor belt speed is detected directly, the speed change of the belt alone is surely detected.

operating principles

An electrical signal is sent from the built-in photo sensor through the rotation of the cam installed on the shaft or from the built-in proximity sensor through the rotation of the metal piece installed on the mechanical unit.
By counting this electrical signal for a given length of time, the shaft rotation speed is detected as the rotation speed per minute. The contact output is executed when the rotation speed reaches below the preset speed.
