6.3 Switches
6.3.1 Switch versions
For position detection, depending on the requirement, mechanical switches in different protection classes as well as inductive proximity
switches Figure 6.41 with the usual output circuits are available.
For the emergency shutdown of the drives before the mechanical end position damper be achieved, mechanically actuated switches
are usually used. A combination with outside placed inductive proximity switches to set additional switching points for example for
reference movements is possible. A mechanical limit switch set consists of two switches with fasteners and cam switch.
An extremely compact version for Linear Axis of the AXC series are the inductive proximity switches for installation in the profile grooves
(Figure 6.42). They are flush with the surface of the aluminum profile of the axis and have almost no interference contour. In this case
a groove insert (Chapter 6.6) will be mounted in addition to assured positioning of the cable in the groove.
The inductive proximity switches are available in the versions PNP-NC (opener), PNP-NO (closer) and NPN-NC (opener). An inductive
proximity switches set consists of two switches with fasteners and cam switch.
All switches are installed factory-provided.
