When mounted to any rotating shaft, the PM Series Encoder provides a single channel square wave output for speed/position control. The Encoder can be used to supply digital feedback for motor speed control and speed indication. The small size of the PM Series Encoder makes it easy to use where space is limited. The Screw Mount design has a 10-32 threaded shaft that is easy to mount. Special mounting brackets and couplings are not required. The Face Mount design has three tapped mounting holes and a snychro groove.
