Festo SFAH Series Flow Sensor, 5L/min Maximum Flow Rate, 0.1L/min Minimum Flow Rate - SFAH-5B-Q6S-PNLK-PNVBA-M8, Numeric Part Number:8158414


This flow sensor monitors low-volume gas flow in industrial automation systems, providing bidirectional thermal measurement of mass and volumetric flow for applications using air, nitrogen or argon. It operates from ambient to media temperatures of 0°C to 50°C and is intended for inline pneumatic integration with tubing O.D. 6mm and an M8 plug electrical connection.

Features & Benefits


• Measures 0.1 to 5 l/min for precise low-flow control
• Withstands up to 10 bar for high-pressure pneumatic systems
• Outputs 0 to 10V or 4 to 20 mA for easy integration with controllers
• Two switchable PNP/NPN outputs for flexible signalling
• IO-Link COM2 enables fast cycle times down to 4 ms
• Reinforced polyamide housing reduces weight while resisting wear

Applications


• Suitable for compressed Air monitoring in machine tooling
• Ideal for leak detection in pneumatic assemblies
• Used with process control systems requiring flow diagnostics
• Can be used for gas dosing where minimal flows are critical

How is the electrical connection provided and protected?


It uses an A-coded M8x1 plug with reverse-polarity protection across all pins and supports a 22V to 26V DC supply range.

How does the device report measurements digitally?


It communicates via IO-Link Device V1.1 using the Smart Sensor profile with a 14-bit measured-value channel and BDC status bits.

What output options are available for integration?


Analogue outputs include 0 to 10 V, 1 to 5V or 4 to 20 mA, and there are two configurable transistor switch outputs with a 100 mA maximum.

What materials contact the medium and how do they affect use?


Flow-path materials include anodised aluminium, NBR Seals and silicon components, suitable for compressed Air to ISO 8573-1:2010 and inert gases.
