Line the parts up with the mounting holes on the back of the motor. It doesn't matter which way the encoder is facing, but for cable management purposes you may want to have the connector facing the same direction as the motor's wires. Screw the parts onto the back of the motor, tightening until there is no visible gap between the PCB and the plastic base. Do not over-tighten.
Take the plastic encoder wheel and place it on the shaft with the comb-shaped edge facing the motor. Slowly slide the wheel onto the shaft until the combs are in front of the optical sensor on the PCB. Be careful not to push so far that the wheel is contacting components on the PCB.

Get the encoder disk and hex key. Do not touch the surface of the encoder disk, as your fingerprints could affect the operation of the optical sensor. Place the encoder disk on the rear shaft of the motor with the metal coupler facing outward. Slide the encoder disk until the surface of the disk is approximately 1.5mm from the optical sensor on the PCB. Use the hex key to tighten the set-screw on the coupler of the encoder disk.

Getting Started

Checking the Contents

ENC4109 Parts.jpg

You should have received:

  • Plastic encoder cap and base
  • Plastic encoder disk
  • Encoder PCB
  • Two screws
  • 3035 - Encoder Cable

In order to test your new Phidget you will also need:

  • A motor with a rear shaft and compatible mounting holes
  • A motor controller Phidget
  • A Phidget with an encoder input

Connecting the Pieces

Take the plastic base, the encoder PCB, and the two screws. Place the PCB inside the base in the orientation shown above so that it fits in. Place the combined base and PCB on the back of the motor such that the mounting holes line up with the holes in the base. There are two orientations possible- use whichever is more convenient for motor wiring. Place the screws in the two holes in the PCB and screw until the base and PCB are firmly attached, being careful not to over-tighten and damage the pieces.

Take the plastic encoder wheel and place it on the shaft with the comb-shaped edge facing the motor. Slowly slide the wheel onto the shaft until the combs are in front of the optical sensor on the PCB. Be careful not to push so far that the wheel is contacting components on the PCB.
