4.1 Preparation before installing the encoder
4.1.1 Installation cavity for the linear encoder
The method of installation depends on the cylinder design. Generally, the sensor is
installed from the piston rod side. It is also possible to install the sensor from the head
side of the cylinder.
The encoder dimensions are listed in the technical specifications: see "Encoder dimen‐
sions", page 48.
