Analyze the application to make sure that
the proper encoder will be selected for the
machine.
To do this, bear in mind the following considerations
L i n e a r
n L i n e a r
Installation
Consider the physical length of the installation and the space
available for it.
These aspects are crucial to determine the type of linear
encoder to use (type of profile).
Accuracy
Each linear encoder comes with a graph showing its
accuracy along its measuring length.
Signal
Consider the following variables for selecting the type of
signal: Resolution, cable length and compatibility.
Resolution
The resolution of the control of machine-tools depends on the
linear encoder.
Cable length
The length of the cable depends on the type of signal.
Speed
The speed requirements for the application must be analyzed
before choosing the linear encoder.

Shock and Vibration
Fagor linear encoders withstand vibrations of up to 20 g and
shocks of up to 30 g.

Installation
This point considers the physical dimensions of the
installation and the space available for it.
It is essential to determine its type of shaft: Hollow or solid.
Accuracy
Each encoder comes with a graph showing its accuracy
along its measuring length.
