EMFR012 Electronic Hygrostat DIN Rail Humidity Controller
Key Specifications
EMFR012 electronic hygrostat is a compact cabinet humidity controller designed for enclosure moisture management. Built‑in DHT20 sensing element with rotary knob for continuous humidity adjustment. It automatically activates cabinet heaters or cooling fans when humidity exceeds the preset threshold to prevent condensation and protect electrical components.
This hygrostat adopts standard 35 mm DIN‑rail clip mounting for simple installation inside switchgear, control cabinets and energy‑storage enclosures. The rugged PC housing reaches IP20 protection grade, long service life over 50,000 switching cycles, and wide 110V‑220V working voltage. CE & RoHS certified, custom service available.

What Buyers Ask Before Inquiry
It is an **electronic hygrostat** with DHT20 sensor, but it has no digital display. Humidity is set by rotary knob instead of digital input. If you need realu2011time digital humidity readout, choose our CZCSu2011F digital hygrotherm.
The switching difference is 4%RH with u00b13% tolerance at 50%RH. It avoids frequent cycling of heaters or fans from tiny humidity fluctuations.
It uses DHT20 contact type relay output for smallu2011power cabinet heaters and cooling fans. Heavyu2011load equipment needs an external contactor.
