Digital Ring Kits


  • High speed digital pulse train
  • Easy to retrofit
  • Impervious to dust, oil, and water
  • 60 or 120 pulses per revolution
  • NPN open collector output
  • Line driver option available 5 -15 VDC

Digital Ring Kits include a mounting ring, hardware, a magnet wheel, and a sensor. They provide digital feedback from motors with NEMA C face end bells, can generate pulses down to zero speed, and transmit without amplification up to 1,500 feet. This is an ideal pulse generator for speed monitoring, motor control, counting, process control, cut-to-length, and ratio/draw controlling applications.

The DRK Series Ring Kits can be quickly and easily installed on NEMA C face motors or between a motor and gear box. Each kit features a non-contacting digital pulse generator system.

The QDRK Quadrature Ring Kit provides a 60-pulse per revolution quadrature signal, for use with electronic control equipment requiring rotational-direction information. Two signals, 90° out-of-phase, are produced by the sensor. When the leading edge of signal A precedes the leading edge of signal B, shaft rotation is forward. When the opposite is true, the monitored shaft is rotating in reverse.
