The electromechanical hygrostat MRF012 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.<br> <br> <br> <br> Specifications:<br> <br> Switch difference:4% RH (3% tolerance)<br> <br> Permissible velocity:15m/sec<br> <br> Contact type:change-over contact<br> <br> Contact resistance: 100 000 cycles<br> <br> Min. switching capacity: 20V AC/for DC 100 mA<br> <br> Max. switching capacity: 250 VAC,5 (1) A for DC 20W<br> <br> EMC: acc. to EN 55014-1-2,EN 61000-3-2,EN 61000-3-3<br> <br> Connection:3-pole terminal for 2.5mm2;,clamping torque 0.5Nm max.: rigid wire 2.5mm2;,stranded wire (with wire end ferrule) 1.5mm2;<br> <br> Mounting: clip for 35mm DIN rail,EN50022<br> <br> Casing: plastic according to UL94 V-0,light grey<br> <br> Dimensions: 67 x 50 x 38mm<br> <br> Fitting position: variable<br> <br> Operarting/Storage temperature: 0 to +60C (+32 to +140F) / -20 to +80C (-4 to +176F)<br> <br> for Protection type: IP20<br> <br> <br> <br> Note:<br> <br> Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.<br> <br> Please allow 1-3mm slight deviation due to manual measurement.
