For cw, leave Black/Red disconnected
For ccw, set Black/Red wire to ground.

**colours may vary due to cable supplier - please verify with label on unit or contact us if in doubt

 

FOR BINARY ONLY: (For different resolution in gray code, specify when ordering)

All our multi-turn encoders are 12 x 12 bit standard.  For different resolutions, leave some of the wires disconnected as follows:

Single Turn Changes:  The MSB must always be wired and the LSB left unwired to adjust resolution

Multi Turn Changes:  The LSB must always be wired and the MSB left unwired to adjust resolution

 

Example:  If 1024 positions / turn are required with 2048 turns in total, make the following changes:

 

Single Turn Section: Leave pin 3 and 4 disconnected

Multi Turn Section: Leave pin 26 disconnected
Mounting Instructions
To mount encoder on machine:  Option 1 is to mount with 3 screws or, option 2 is to mount using synchroflange mounting brackets.  Hook up the encoder with the connections as described.  Make sure power supply meets specifications.  Attach encoder to mounting bracket as shown.  Attach shaft using a flexible coupling.
