Brand: Festo

Flow sensor SFAB-600U-HQ10-2SA-M12

The Festo industrial component, part number 565401, is a thermal measuring principle device utilizing heat loss to monitor volume and volumetric flow rate in a unidirectional P1 to P2 flow direction. It operates with compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen across an operating pressure range of 0 MPa to 1 MPa (0 bar to 10 bar, 0 psi to 145 psi) and a medium and ambient temperature range of 0 °C to 50 °C. The unit features a flow measuring range from 6 l/min to 600 l/min at a nominal temperature of 23 °C, delivering a flow rate accuracy of ± (3% o.m.v. + 0.3% FS), a zero point repetition accuracy of 0.2 %FS, a repetition accuracy margin of 0.8 %FS, and a temperature coefficient margin of typ. 0.1 %FS/K. Compliance certifications include RCM, c UL us Recognized (OL) under certificate UL E322346, CE marking per EU EMC and RoHS directives, UKCA marking per UK instructions for EMC and RoHS, and RoHS-compliant materials.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
