Frequently Asked Questions
General Encoding
What is an encoder?
Resolution
How can I get a rotary encoder resolution that is not one of the standard resolutions?
What are the minimum and maximum resolutions available with US Digital encoder modules?
How closely does the line density of the encoder disk or linear strip have to match the line density of the module?
Mounting
Can adhesives be used instead of screws?
What is meant by "artwork side of encoder disk?"
How will the gap between the encoder disk and the detector side of the encoder module affect the output?
What is TIR?
Materials
What is the material of the encoder module housing?
What is the encoder module lens made of?
What are the encoder disks made of?
Reliability
Will US Digital encoders work in a vacuum?
Will US Digital encoders work in a radioactive environment?
Will US Digital encoders work in a fluid?
How well do US Digital encoders work in a dusty environment?
What solvents can be used to clean in the vicinity of the encoder modules?
Electrical
What kind of output drives do US Digital encoders have?
I am trying to drive a fairly long length of cable. What kind of additional circuitry should I consider?
I am having some problems with noise affecting my encoder signals. What should I do?
Does US Digital provide encoders with differential line driver outputs?
Typically, how much current do the LED and photodetector IC draw?
Miscellaneous
How thick are US Digital encoder disks and/or strips?
Does US Digital provide optical encoder rotary disks and/or linear strips?
On the HEDS-9000/9100/9200 encoder modules, there are two metal straps on either side of the five pinouts. What are they for? Can they be cut or removed?
