low cost solution for measuring shaft speed/position

When mounted to any rotating shaft, the PT Series Encoder provides a single or dual 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 PT Series Encoder (2.0" dia., 900" long) makes it easy to use where space is limited. The hollow shaft design is easy to mount with no coupling or tedious alignment procedures.
