INTRODUCTION
WayCon Positionsmesstechnik GmbH is a manufacturer of high quality draw wire position sensors for
industrial use. Due to its small overall size, its short assembly time and its possible customisation, the
SX sensor technology is a cost-effective and flexible solution for a wide range of industrial applications.
The dynamics of the draw wire transducer allows a high motion speed and acceleration of the
measuring target. Its rugged design and high quality makes applications in harsh industrial
environments possible. Special instruments are available with mounting service of encoder on site, as
well as customised versions of housing.
example: SX50
measuring rope
tension spring
rope capstan
Sensor principle:
The key component of a draw wire sensor is a highly flexible steel wire rope, that is winded singlelayered on an ultra light capstan. This capstan is connected to the sensor housing by a pre-stressed
spring. The end of the steel wire rope, that is equipped with a rope clip gets connected to the target
object. As soon as the distance between sensor and target object changes, the steel wire rope gets
pulled out of the sensor and is rolled off the capstan (or vice versa). The shaft of the capstan is
connected to a potentiometer (for analog output signals), or to an encoder (for digital output signals). If
there is a rotation of the capstan due to a change in the distance to the target object, the sensor
element will turn proportionally. This way the potentiometer, or the encoder converts a linear movement
into a proportional electrical signal. If a standard analog output signal, like 0...10 V or 4...20 mA is
needed, the sensor is equipped with an additional electronics.

WARNING NOTICES
•
Don‘t let the rope snap back. If the rope is retracted freely, this may lead to injuries (whiplash effect) and the device may be damaged.
Caution when unhooking and retracting the rope into the sensor.
•
Never exceed the specified measurement range when extracting the rope!
•
Do not try to open the device. The stored energy of the spring drive may lead to injuries when being mishandled.
•
Do not touch the rope when operating the sensor.
•
Avoid guiding the rope over edges or corners. Use a deflection pulley instead.
•
Do not operate the sensor if the rope is buckled or damaged. A ripping of the rope may lead to injuries or a damaging of the sensor.

INSTALLATION
•
Mount the sensor at the designated place by using the fixing holes before extracting the rope and before attaching the rope to the
measuring target.
•
Open the rope clip after the sensor is fully mounted and extract the measuring rope. Hook the rope clip on the measuring object and
close the bracket of the clip. For safety reasons put a screw driver trough the clip to extract the rope.
•
Check the track of the measuring target on collision with the sensor housing and on exceeding the specified measurement range. When installing the sensor make sure
that the rubber stopper does not touch the rope outlet.
•
Connect the electronics according to the sensor type. When laying the cables be careful not to under-run the minimal allowed bending radius of the cable (5 x cable
diameter).
•
The rope must be extracted from the sensor vertically. The maximum variation from the vertical is 3°. Avoid carefully extracting the rope at an inclination, since the
durability of the instrument would shorten considerably. If it is not possible to keep the limit of 3°, a deflection pulley has to be used.
•
The measuring range begins after approximately 2 mm extracted rope (=zero point). The mechanical reserve at the end of the measuring range is about 20 mm.
•
When mounting outdoors protect the sensor and the rope from icing at temperatures below 0 °C.
•
Guide the rope preferably in corners or guarded in channels to prevent pollution or accidental touch.
•
When operating the sensor, take care not to let the rope snap back by mistake or extract the rope over the specified measurement range, as this might destroy the
sensor.
•
Maintenance: These instruments are maintenance-free. If however, the rope is soiled due to adverse environmental conditions, it can be cleaned with a cloth drenched
in resin-free machine oil.

SX80, SX120: standard rope outlet, rope outlet sideways top (S1)
The sensor is usually installed by using the regular mounting plate (see technical drawing on page 4).
By disassembling the mounting plate, there are 4 threads (2 x M3, 2 x M5) in the sensor housing for alternative installation.
SX80: rope outlet sideways bottom (S2), rope outlet bottom (S3)
SX120 rope outlet sideways bottom (S2), rope outlet bottom (S3)
Sensors with option rope outlet S2 and S3 have a modified base
plate.
Sensors with option rope outlet S2 and S3 have a modified base

ACCESSORIES
Deflection pulley - UR2
The rope must be extracted from the sensor vertically. The maximum variation from the
vertical is 3°. A deflection pulley allows a change in the direction of the wire rope. Several
pulleys may be used. The rope clip must not be guided over the deflection pulley.
material:
anodised aluminium, POM
mounting: by 2 hexagon socket or countersunk screws M6,
vertical or horizontal mounting possible.
Ball bearings: with special low temperature grease and RS-sealing.
Temperature: -40...+80 °C.
Rope extension - SV
For bridging a greater distance between the measuring target and the sensor a rope extension
can be applied. The rope clip must not be guided over the deflection pulley.
Please specify the length needed in your order (XXXX). The minimum length is 150 mm:
SV1-XXXX: rope extension (150...4995 mm)
SV2-XXXX: rope extension (5000...19995 mm)
SV3-XXXX: rope extension (20000...40000 mm)
Magnetic clamp - MGG1
Use the magnetic clamp to quickly attach the rope to metallic objects without any assembly time. A rubber coating
provides gentle contact (e. g. on varnished surfaces) and prevents from slipping due to vibration.
The magnet consists of a neodym core for an increased adhesive force of 260 N. The hook makes it easy to attach the
rope clip.
