INTRODUCTION

WayCon Positionsmesstechnik GmbH is a manufacturer of high quality draw wire position trans­ducers 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. Sensors specifically designed for off-shore use receive a
HARTCOAT surface, which makes them resistant to e. g. sea water. Special instruments are
available with mounting service of encoder on site, as well as customised versions of housing.

rope capstan

Sensor principle:
A constant spring force coils the measuring rope accurately, single-layered on an ultralight rope

capstan, so that its linear motion is converted into rotation. The sensor element (encoder) provides
the output signal required.

OPTIONS

HG

A reinforced spring drive provides a greater rope tension and allows a higher rope acceleration. Please note the different dimensions of the housing and the higher
traction of the rope. This option is only available for the series SX50.

CO

By the use of a special technology all components of the housing and the inner mechanics become HARTCOAT® coated. This coating is a hartanodic oxidation that
protects the sensor from corrosion by aggressive media (e. g. sea water) with a hard ceramics-like layer. The sensor can thus be used off-shore.

IN

The analogue signal of the sensor is increasing by extracting the rope (standard).
Option IN inverts the signal, i. e. the signal of the sensor declines by extracting the rope.

L25 / L10 / L05 / L02

Improved linearity on 0,25 %, 0,10 % or 0,05 % of measuring range. Resolution, repeatability and sensibility remain unchanged.

L02: Improved linearity on 0,02 % of measuring range. Resolution, repeatability and sensibility remain unchanged. This option is only available for incremental
sensors.

IP67

Use option IP67, if sensor is fully immersed in water (temporarily). Note that with this option there may occur a light hysteresis in the output signal due to the special
sealing. The max. acceleration is reduced to 60 % of the specified value.

mounting

The sensor can be installed by using the mounting plate (see drawing
above).
By disassembling the mounting plate, there are 4 threads (2 x M3, 2 x M5)
in the sensor housing for installing.
