Media temp. -15 ... 60 o C
Media temp. limit temperatures up to 85 o C are allowable for short periods. Higher
temperatures are possible, provided that the limit is safeguarded by
suitable measures (e.g. water tube trap, see Accessories for Pressure
Switches / Transmitters)
Ambient temperature -15 ... 60 o C
Ambient temp. limit at temperatures below 0 o C, ensure that no water condensation can
arise in the sensor and in the switching device
Switch function/capacity SPDT Microswitch 250 Vac; capacity 5 A inductive, 8 A resistive
