The NOXT MFR012 mechanical hygrostat is a DIN‑rail mounted humidity switch designed for automatic cabinet humidity management and condensation prevention. It adopts a mechanical sensing structure with an adjustable relative humidity setting range from 40%RH to 90%RH, reliably activating cabinet heaters or cooling fans to stabilize internal humidity and avoid moisture damage to electrical components.

Built with a flame‑retardant PC housing, the MFR012 features high switching capacity, long service life up to over 50,000 switching cycles and IP20 protection class. SPDT change‑over contact enables two‑way control: switching on heaters for dehumidification or starting filter fans for ventilation. Simple 35 mm DIN rail clip‑on installation and clear wiring terminals save on‑site assembly time.
