Omron flow sensor D6F-W04A1

Omron D6F-W04A1 – MEMS Air Flow Sensor (0–4 m/s)

The Omron D6F-W04A1 is a compact, precise MEMS-based flow sensor for measuring airflow. It is ideal for applications such as filter condition monitoring, ventilation control, cooling systems in IT and industrial environments, and general airflow sensing in HVAC systems.

Measuring principle:
The sensor measures air flow using a thermal mass flow principle (MEMS technology) with high repeatability and temperature compensation. The system is low-maintenance and robust against dust thanks to an integrated protection system against particle contamination (dust segregation).

Technical data:

– Measuring range: 0 to 4 m/s (air)
– Output signal: 1 to 5 V DC (analog, non-linear)
– Supply voltage: 10.8 to 26.4 V DC
– Accuracy: ±5% of final value (full scale)
– Repeatability: ±0.4% FS
– Current consumption: max. 15 mA
– Connection: 3-pin (V+, GND, Vout)
– Operating temperature: –10 °C to +60 °C
– Protection class: IP40
– Housing material: high-performance plastic (PPS)
– Dimensions: approx. 39 × 20 × 9 mm
– Weight: approx. 6.3 g
– Installation position: horizontal or vertical (note air flow direction)

Special features:

– High measuring accuracy with a compact design
– Dust protection through internal flow layout
– Temperature compensated and ready for use without calibration
– Low power consumption
– Compatible with microcontrollers, data loggers and PLC systems with analog input

Typical applications:

– Ventilation and air conditioning units (e.g. for filter monitoring)
– Airflow monitoring in electronics enclosures or server cabinets
– Process air control in industrial plants
– Energy optimization in HVAC systems
