Category FAQs

What does an air flow switch do?
An air flow switch monitors air velocity and triggers a signal when airflow reaches or falls below a set threshold.

What is a PNP transistor output?
A PNP output provides a positive switching signal, commonly used in industrial control systems for sensor integration.

What does normally open (NO) mean?
Normally open means the circuit remains open until the airflow condition is met, at which point the switch closes and sends a signal.

Where are air flow switches commonly used?
They are used in HVAC systems, ventilation ducts, cleanrooms, and industrial air handling systems.

Can this sensor detect low airflow conditions?
Yes, with a minimum switching range starting at 0.5 m/sec, it is suitable for detecting relatively low airflow levels.

Is this compatible with standard industrial systems?
Yes, 24 VDC operation and PNP output are widely compatible with industrial PLCs and control systems.

Does the cable come pre-installed?
Yes, the unit includes a pre-attached 2-meter ÖLFLEX cable for convenient installation.

Can this be used for safety or alarm systems?
Yes, it can be used to trigger alerts or shut down systems if airflow conditions fall outside acceptable limits.
