MFR 012 Electromachanical Hygrostat Advantage: * Adjustable relative humidity * Easily accessible terminals * Change-over contact * Clip Fixing * High switching capacity The electromechanical hygrostat MRF 012 is designed to control enclosure heaters so that the dew point is raised when a critical relative humidity of 65% is exceeded. In this way condensation and corrosion is effectively prevented. Switch difference* 4% RH (±3% tolerance) Relative humidity range 35% -95% Allow wind speed 15m/sec Contact type change-over contact Contact resistance < 10 m Ohm Service life >50,000 cycles Min. switching capacity 20V AC/DC 100 mA Max. switching capacity 25 VAC, 5 A Connection 3-pole terminal for 2.5mm², clamping torque 0.5Nm max.: rigid wire 2.5mm², stranded wire (with wire end ferrule) 1.5mm² Mounting clip for 35mm DIN rail Casing plastic according to UL94 V-0, light grey Dimensions/ weight 67 x 50 x 38mm Weight approx. 60g Fitting position Variable Operating/Storage Temperature 0 to +60°C (+32 to +140°F) / -20 to +80°C (-4 to +176°F) Protection Level IP20
