Supported Applications
The Omega MFR012 series is a mechanical hygrostat designed to control relative air humidity inside enclosures. The device activates heaters (de-humidifiers) or cooling fans at set humidity levels to prevent condensation and corrosion. Documented applications include electrical and electronic enclosures, telecommunication systems, display panels, ticket dispensers, ATM machines, and access/parking control systems.
Operating Conditions & Performance
The MFR012 operates within an ambient temperature range of 0 to 60°C (32 to 140°F) with a storage temperature capability from -20 to 80°C (-4 to 176°F). The adjustment range covers 35 to 95% relative humidity, and the series supports measurement up to 100% RH. Switching difference (hysteresis) is approximately 4% RH @ 50% relative humidity. Permissible air velocity is rated at 50 ft/sec (15 m/s). The unit carries an enclosure rating of NEMA 2 (IP20).
Electrical Switching Specifications
- Contact Type: Change-over contact (SPDT)
- Maximum Switching Voltage: 250 Vac
- Minimum Switching Capacity: 100 mA @ AC/DC 20 V
- Maximum Switching Capacity: 5 A @ AC 230 V (resistive load); 1.0 A @ AC 230 V (inductive load at cos j = 0.8); DC 20 W
- Contact Resistance: <10 mOhm
- Service Life: 100,000 cycles
Note: The critical relative humidity for most components is documented as 65%. Above 65% RH, condensation can cause malfunction of electronic equipment. Additionally, attention is required that 250 V should only be switched in a non-condensing environment.
Compliance
The series meets EMI/EMC compliance standards EN 55014-1-2, EN 61000-3-2, and EN 61000-3-3.
Configuration Options
The MFR012 series is configured for DIN rail mounting via a clip for 35 mm (1.4") DIN rail per standard EN 50022. Electrical connection utilizes a 3-pole terminal accepting up to 3 x AWG 14 max [2.5 mm² (0.1 in²)]. The unit is powered by a supply range of 20 Vdc to 230 Vac.
Physical Characteristics
- Dimensions: 67 H x 50 W x 38 mm D (2.64 x 1.97 x 1.5")
- Weight: 60 g (2 oz)
Key Product Differences
The series is represented by the model number MFR01201220000, described as a mechanical humidity control with SPDT output, covering 35 to 100% RH and operating on 20 Vdc to 230 Vac. The general model numbering format follows MFR012 - <MODEL NUMBER>.
