INTRODUCTION
The Draw Wire Series SX300 by WayCon is designed for use in combination with hydraulic cylinders and measuring the cylinder position.
Especially designed for long stroke cylinders with pressurized housings to be anged directly to the cylinder head. By giving feedback signals to
a machine control unit, it is possible to control the position of a cylinder, to program specic movements or to manage synchronous movements
of several cylinders. Due to its small overall size, its short assembly time and its possible customisation, this sensor technology is a cost-eective
and exible solution for a wide range of industrial applications.
A constant spring force coils the measuring rope accurately single-layered on a wire rope capstan, so that its linear motion is converted into
rotation. The sensor element (rotary encoder) provides the output signal required. Due to the dynamics of the draw wire transducer high
motion speed and fast acceleration of the cylinder piston can be measured. Its high quality makes applications in harsh industrial environments
possible.

INSTALLATION
The wire xation unit has to be screwed into the piston of the
cylinder and locked with counter nut.
Note: use screw locking device. If it is not possible to work
through the cylinder head bore, you have to take o the
cylinder head (please refer to the cylinder manual).
Drawing contains O-ring (blue) installed in cylinder head bore.
This is not necessary! The SX300-...-F2 already features an O-ring
sealing on its ange.
Install 3 stud bolts at the cylinder head.
It is necessary to use stud bolts on the underside of the sensor
ange, as conventional screws (e.g. according to DIN 912)
cannot be mounted for space reasons.
Note: Studs have to be greased with MoS2 during assembly,
unless otherwise described. Please follow the operating
instructions for the cylinder.
Move the transducer near the cylinder bore. Use a crane if
necessary. Remove the red protective cap at the cable outlet
of the sensor. Open the rope clip, guide the rope through the
hole and hang the rope clip in the clip xation. Finally, close
the rope clip again.
Note: Do not let the draw wire snap! If the draw wire retracts
freely into the sensor, it can cause injury and damage the
device. Take care when unhooking and retracting the draw
wire into the sensor. Avoid leading the draw wire over edges
or corners.

INSTALLATION
Move the transducer toward the cylinder head and insert the
stud bolts through the bores in the ange.
Note: Avoid leading the rope over edges or corners. Be
careful not to damage the O-ring. Do not operate the sensor
if there are buckles or damages in the draw wire. Tearing the
draw wire may cause injury or damage to the sensor.
Mount the xing screws through the ange and tighten them
crosswise with a torque of 100 Nm in the rst step.
Note: The fastening screws must be greased with MoS2
during assembly, unless otherwise described. Please follow
the operating instructions for the cylinder.
Screw the nuts onto the stud bolts at the bottom of the
ange. Tighten the bolts and nuts crosswise to the specied
torque. Observe the following values if the manual of the
cylinder does not prescribe a torque:
• 145 Nm for M16, quality 8.8
• 215 Nm for M16, quality 10.9
• 250 Nm for M16, quality 12.9
Note: The nuts must be greased with MoS2 during assembly,
unless otherwise specied. Please follow the operating
instructions for the cylinder.
