WCS* Read Head Position Encoding System
Product Description
Overhead Conveyors
Many vehicles have to be positioned on a circular track—the WCS offers the optimal solution
for this. Branches (track switches) and curves can be created. The WCS3 is particularly well-
suited for this task. After a power failure, the current position of the vehicle is transferred to the
control panel immediately; the vehicle does not have to be moved. The WCS can also be used
for distances longer than 314.573 m.

Harbor Applications
The WCS with protective enclosure is used for material handling plants in particularly demand-
ing areas such as harbors, offshore installations, and ships. To meet the requirements of these
areas, the WCS includes an IP69-compliant protective enclosure that, in addition to protecting
against dust and humidity, has been specifically designed for resistance to aggressive sub-
stances such as salt water, salty air, acids, and alkalis. It offers increased impact resistance
compared to typical outdoor sources of interference such as falling branches and hailstorms. In
combination with built-in heating, the WCS can even be used in snow and temperatures as low
as -40 °C. The indicator LEDs and the display are always visible through the translucent enclo-
sure material.
