Standard Primary Feedback Connector (Encoder and Hall)

I have two standard feedback connectors:

  • The HD15-FC for differential encoders and single ended hall (commutation) sensors
  • The MF10-FC for single ended encoders and single ended hall sensors

The hall sensors are not used in two cases:

  • Brush motors (of course)
  • Brushless motors that can only be used with sinusoidal commutation, such as some Yaskawa motors

If the motor provides differential commutation signals (e.g. many commutating encoders), use the positive signal, and do not connect the negative signal.

I always define positive movement to be clockwise when you are facing the motor.

A and B are the standard quadrature signals; I is the index signal (sometimes called Z), and U, V, & W are the commutation signals.

I provide two power pins and two ground pins to make it easier to connect motors with separate encoders and hall sensors.

HD15-FC Feedback Connector

I use the high density 15-pin D-Sub connector for differential encoder feedback because it's rugged, it is readily available, cables are readily available, it is easy to wire, and it has enough pins. A number of other companies, including AMC, Copley Controls, and Galil, also use HD15 connectors but each one has a different pin out.

  • The motor uses a HD15 Male connector
  • The controller uses a HD15 Female connector

MF10-FC Feedback Connector

I choose the Molex Mini-Fit Jr 10 position connector for my single ended feedback connector because it's affordable, readily available, easy to crimp, and has the right number of positions.

The motor uses the receptacle housing so it can be plugged into a PCB-mount plug connector (PCB-mount receptacle connectors are not available, GRRRR!).

IMPORTANT NOTE: Mini-Fit Jr pins are available with tin or gold finishes. You should not mix the finishes; use only gold or only tin on all your contacts. Tin is cheaper and works fine in most cases.

TE's Val-U-Lok connectors are supposedly interchangeable with the Mini-Fit Jr connectors.

The connectors are cheaper at Mouser, but the pins are cheaper at Digikey if you get them in cut tape.

  • The motor uses the receptacle housing and crimp sockets.
    • I am currently using Molex 39-01-2100 receptacle housings and Molex 39-00-0038 crimp sockets.
  • The controller uses the plug housing and crimp pins.
    • I am currently using Molex 39-01-3103 plug housings and Molex 39-00-0040 crimp pins.
