With the help of limit switches, data can be easily and reliably recalled from the system – for example, the on/off information that can be electrically forwarded to the control system.
Our product range includes mechanical and inductive limit switches.
Several operating options
In mechanical models, the motion of the valve stem is integrated in the switch that rises or lowers with the motion of the valve and signals the opened or closed state of the valve.
An inductive switch generates an output signal if a metallic or other conductive material approaches the sensing surface.
The operation of the magnetic switch is based on changes in the magnetic field while the valve stem rises or lowers. Magnetic limit switches are also applicable in explosion hazard areas
