QDRK 254TC Quadrature Ring Kit

QDRK 254TC Quadrature Ring Kit

The QDRK 254TC Quadrature Ring Kit provides a digital, quadrature (bi-directional) feedback signal from motors with NEMA C Face end bells. The QDRK Series is designed for use with electronic control equipment requiring rotational direction information. Two signals, approximately 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 reverse is true, the monitored shaft is rotating in the opposite direction.

The QDRK Ring Kit consists of three components the NEMA-C Frame Ring, a Quadrature Hall Effect Sensor, and a Magnet Wheel mounted on a hub bored to fit the size of the monitored shaft. A special sensor mounting assembly has been added to the standard DRK Ring Kits to ensure proper mounting of the Quadrature Sensor.
