Wireless Proximity Switches / Issue: 09.2004
The product range of wireless proximity switches includes flush mountable as well as non
flush mountable sensor heads. Flush mountable sensor heads can be mounted in the
machine in a way that they are particularly well protected against mechanical damages.
Compared with that, the non flush mountable sensor heads have a significant higher
switching distance. However, their plastic cap has to stand out of the metal environment as
shown in the figure.
