This is a small ball bearing construction, rotary encoder without index that goes up to 3000 rpm.

The encoder comes with a 1 meter cable and 2 mounting screws.


This quadrature encoder can be read by an encoder interface. To attach the shaft of this encoder to a motor or some other device, you can use a shaft coupler. See the "Compatible Products" tab for details.

Encoder Interfaces

This quadrature encoder must be read by an encoder interface. These interfaces will interpret the two quadrature signals in order to determine the continuous position of the rotating part. The following interfaces are compatible with this encoder:

Image Part Number Price Number of Encoder Inputs Count Rate Max
1047_1 $100.00 4 1E+06 pulses/s
1057_2 $60.00 1 2E+06 pulses/s
1065_0 $80.00 1 500000 cycles/s
ENC1000_0 $15.00 1 400000 pulses/s

Shaft Couplers

If you need to connect the main shaft of this motor to the shaft of another device, you can use a shaft coupler:

Encoder Cables


The easiest way to connect your encoder to a Phidgets encoder interface is to use a Phidgets encoder cable, cut it to the desired length and solder the encoder wires to the encoder cable as follows:

Alternatively, you could buy the male connector (Molex part 50-57-9405), and crimp it onto the end of the cable, if you have the appropriate tools.
