Maximum Pressure
To ensure long service and life select the pressure range as follows:
Dynamic pressure applications Pmax = 75% of Range
Static pressure applications Pmax = 100% of Range
Maximum Pressure that can be applied is 125% of pressure range
Installation
The Switches can be mounted directly on the connecting thread. Sealing grooves are machined into the end face of the
parallel threads for the use with sealing washers. A mounting bracket is available if required.
