Body: Brass nickel-plated or 1.4571, Spring: 1.4571, seals: FKM, Display: Polycarbonate / 1.4301
Temperature range:
-20 to +120 °C, Environment: max. +80 °C
Protection class:
IP 65
Measurement principle:
Spring loaded float

Switch type:
Closer (NO)
Switching capacity:
G 1/2": 230 V AC, 60 VA, max. 3 A / 230 V DC, 60 W, max. 3 A, G 1": 250 V AC, 100 VA, max. 5 A / 250 V DC, 100 W, max. 5 A
Media:
Oils and other fluids with 30 - 600 cSt viscosity (Option -W: water and aqueous media)
