SNG-Q Series, quadrature speed and direction sensor, plastic housing, 45 mm housing length, Amp Superseal 1.5 connector 282106 with 145 mm cable, straight exit The SNG-Q Series Quadrature Speed and Direction Sensors are designed to provide both speed and direction information. Speed information is provided from digital square wave outputs; direction is provided using a quadrature output with signals 90° phase shifted from each other. With the quadrature output, target direction is determined by output lead/lag phase shifting.
