Electronic Switches (I) P. Ltd; offers 6 Digits, Preset Counter with 19 mm height seven segment LED display. Units operates on 220 Volts AC supply and accepts input from sensors. These micro-controller based digital counters are widely used for counting number of turns at coil winding machine. There is function for counting UP or DOWN. When the number of turns are more than the required value, the counts can be reduced to the required value by rotating the coil in the opposite or reverse direction.


  • NPN, PNP or Both outputs
  • Multiple ranges available as required
  • LED indication for output status
  • Non Critical alignment between the Sensors
  • Available in M 18 Brass Plated Housing
  • Also available in ABS Plastic Housing
