IE2-1024 Encoder Family


The IE2-1024 [1] is an incremental, two-channel magnetic encoder family with 64 to 1024 lines per revolution. Requires a 5 V supply voltage and outputs two digital square waves that can be used for the indication and control of both shaft velocity and direction of rotation as well as for positioning.


These encoders have 6 wires with the following functions:

Pin Function
1 Motor -
2 Motor +
4 Vdd
5 Channel B
6 Channel A

The connector may vary so, when in doubt, simply note that the wires are numbered from 1 to 6 starting from right to left, or better, starting from the wire that is partially colored in red.
