Encoder mode: “DETENTED2”, 24 steps per turn

Pinout: http://www.avishowtech.com/mbhp/images/encspecs17.gif

Note: the rightmost picture is “top down” (as seen from the top of the encoder looking down to the shaft)

pin “A” goes to D1

pin “C” goes to Vs

pin “B” goes to D0

(This means that, encoder C pin is “common”. Encoder B pin goes to lower numbered DIN pin (of two pins assigned to that encoder) and encoder A pin to higher numbered DIN pin.)

the detent can be removed

M-SW-ROT, detented rotary encoder

Encoder mode: “DETENTED2”, 24 steps per turn

pinout: http://www.voti.nl/docs/rotary-encoder.jpg

if you view the encoder from the top with the pins pointing towards you;

left pin goes to D1 (highest numbered din pin)

middle pin goes to D0 (lowest numbered din pin)

right pin goes to Vs (ground)

the detent can also be removed

Pollin (http://www.pollin.de) has cheap encoders with button;

Encoder mode: “DETENTED”, 16 steps per turn

Pin connection is (laying the encoder before you, cap pointing towards you, pins on top):

0: GND (button)

1: GND (enc)

2: pin A (eg D0)

3: pin B (eg D1)

4: pin C (button, eg D2)
