Electrical connection M12x1 acc. to IEC 947-5-2 - connector are not included in delivery, max. allowable voltage 30 V.
The pressure switch will lose the Ex approval when using other connectors than those listed in the data sheet.
*1) Setpoints should be ideally in the middle of the switching pressure range.
Reference pressure = atmospheric pressure.
Switching pressure must not exceed the indicated values.
*2) Max. values.
