WCS* Read Head Position Encoding System
Product Description
The variants available can be found in the product selector at https://www.pepperl-fuchs.com,
as well as in the model overview for read heads, see chapter 10.
Mounting System
There are three different mounting systems available for mounting the code rail. The bracket
system, the WCS3 aluminum profile system, and the WCS2 aluminum profile system with fix-
ture for a guide trolley. The three mounting systems can be screwed directly to the surface or
mounted on standard C profiles.
The bracket system is the easiest to mount as it features mounting brackets for straight section
elements and curved sections (vertical, horizontal). The brackets are screwed directly to the
code rail and to the surface and C profile.
As an alternative to the mounting brackets, the WCS3 aluminum profile system provides better
stabilization of the code rail and simplified mounting for long, straight sections. In this case, the
code rail is inserted into an extruded aluminum profile developed for the WCS and fixed in
place with a fixing cord. The aluminum profile rail is clipped to plastic brackets and attached to
the surface with a C profile.
The WCS2 aluminum profile rail system with guide trolley is intended for applications with high
running tolerances. The aluminum profile accommodates the code rail and the guide trolley.
The guide trolley is connected to the vehicle via a free-running tappet and guarantees that the
read head is always in the optimal position in relation to the code rail. At the same time, the
read head is decoupled from vehicle vibrations. Use of the guide trolley is generally recom-
mended with the WCS2 read head due to the low read head gap. For the WCS3 read head with
outdoor protective enclosure, an optional guide trolley can be used in combination with the
WCS2 profile rail.
