Electrical Ratings
10 Amp at 250V ac 50Hz Inductive Load
1 Amp at 30V dc Inductive Load
For other voltages and currents, please consult our Technical Sales Department.

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
The maximum pressure that can be applied is 125% of the 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.

Vacuum Setting
At ambient pressure, the switches will be in the operated condition; consequently, the wiring should be reversed, i.e., NO becomes NC.

Connecting Threads
All Connecting threads used in industry are available, including British, American and metric. Please state the required connection thread when ordering.
Flanged fittings are available, and most types of Hygienic fittings can be supplied assembled directly onto the Pressure Switch. If flush diaphragms are required, please consult our Technical Sales Department.
Alternative Wetted Parts are also available. Please contact our Technical Sales Department for options and information on this.
