Reliable Products Trustworthy People Shaft Speed Pulse Generators Features • NEMA C Frame • High speed digital pulse train • Kits include mounting ring, hardware, magnet wheel, and sensor • Easy to retroﬁt • Impervious to dust, oil, and water • 60 or 120 pulses per revolution • NPN open collector and line driver options Description Electro-Sensors digital ring kits 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. Fits NEMA Frame Shaft Size 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 'Output A' precedes the leading edge of 'Output B', shaft rotation is forward. When the opposite is true, the monitored shaft is rotating in reverse. Quadrature Output (QDRK Series) Provides two square wave output pulses offset from each other by 90°. The pulses lead or lag each other depending on the direction of shaft rotation. Output A Output B Quadrature Sensor Adjustment (QDRK Series) All ring kits are preset at the factory to a 0.020" gap distance and aligned for a 90° phase shift. To adjust gap distance between the magnet ring and the sensor, use these steps (see figure 1): 1. With the mounting ring and magnet wheel mounted, set the gap adjustment screw so that it extends approximately 1/8" below the adjustment block. 2. Place the sensor with the guide post fitting into the guide hole and the barrel of the sensor down the neck of the ring. The sensor face should be resting on the magnet wheel. Gap Adjustment Screw Guide Post Set Screws Adjusted when Gap is Set 3. Apply a slight downward pressure on the sensor and turn the gap adjustment screw clockwise until it rests on the base of the junction box. 4. With continued pressure on the sensor, adjust the gap adjustment screw 3/4 turn clockwise, raising the face of the sensor slightly off the magnet ring, and tighten the set screws on the neck of the ring kit. This procedure will result in the sensor being gapped to approximately 0.020". The kit is now ready to run. 6111 BLUE CIRCLE DRIVE
