- Hello, fellow geeks, and welcome to Another Geek Moment.
I'm Reid and today I will be talking about
CUI's AMT Modular Encoder Series.
CUI's AMT Series
is a range of rugged,
highly accurate modular encoders available in
incremental, absolute, and commutational versions.
Thanks to its innovative design,
the AMT series is not susceptible to contaminants
such as dirt, dust, and oil,
that often plague encoders in industrial environments.
AMT's design also simplifies the assembly process.
Mounting and alignment are reduce to mere seconds
combined with a wide operating temperature
of -40 to 125 degrees Celsius,
a compact package,
high accuracy, and a low current draw,
the AMT encoder provides a compelling solution
for industrial, automation, robotics,
and renewable energy applications.
Today I will be doing two demonstrations
to showcase CUI's AMT encoders,
the first of which will be an environmental test
to compare the difference between an optical encoder,
which is mounted on this side,
to an AMT encoder which is mounted over here.
What I'll do is I'll turn this on to show you the waveforms.
Looking at the O-scope,
the top two waveforms are from the optical encoder
while the bottom two waveforms are from the AMT encoder.
What I'll do now is introduce chalk dust
to show you what happens.

As you see,
the optical encoder
has been severely malformed
while the AMT encoder
still has a nice waveform.
And here you can see
after only 24 hours in a dusty environment,
the waveform on the optical is nearly nonexistent,
whereas the CUI AMT encoder has not been affected.
Now that we've demonstrated the AMT encoder
in a dusty environment,
I would like to demonstrate it
in a submerged oil environment.
What I have here is an LCD screen
to show the RPM and direction of the motor,
taking readings off of the AMT encoder.
I have a brushless DC motor and a motor driver board.
As you can see I'm getting RPM readings
and direction readings off of the motor.
I will now submerge it in oil.

You will notice we did not lose
any valid information from the encoder.
We still have our direction and RPM readings.
Now you can see that AMT encoders
can handle the entire gauntlet of industrial contaminants,
dust, oil, and dirt.
CUI's AMT Encoder Series includes AMT10,
AMT11, AMT20,
AMT31,
all of which can be found at digikey.com.
Thanks for watching.
